Passage 1The Human Genome Project
Unit 7 Biotechnology and Human Health
The Human Genome Project
Since the beginning of time, people have yearned to explore the
unknown, chart where they have been, and contemplate what they
have found. The maps we make of these treks enable the next
explorers to push ever farther the boundaries of our knowledge -
about the earth, the sea, the sky, and indeed, ourselves. On a new
quest to chart the innermost reaches of the human cell, scientists
have now set out on biology's most important mapping expedition:
the Human Genome Project. Its mission is to identify the full set of
genetic instructions contained inside our cells and to read the
Unit 7 Biotechnology and Human Health
complete text written in the language of the hereditary chemical DNA
(deoxyribonucleic acid). As part of this international project, biologists,
chemists, engineers, computer scientists, mathematicians, and other
scientists will work together to plot out several types of biological
maps that will enable researchers to find their way through the
labyrinth of molecules that define the physical traits of a human being.
New maps developed through the Human Genome Project will
enable researchers to pinpoint specific genes on our chromosomes.
The most detailed map will allow scientists to decipher the genetic
Unit 7 Biotechnology and Human Health
instructions encoded in the estimated 3 billion base pairs of nucleotide
bases that make up human DNA. Analysis of this information, likely to
continue throughout much of the 21st century, will revolutionize our
understanding of how genes control the functions of the human body.
This knowledge will provide new strategies to diagnose, treat, and
possibly prevent human diseases. It will help explain the mysteries of
embryonic development and give us important insights into our
evolutionary past.
Unit 7 Biotechnology and Human Health
The development of gene-splicing techniques over the past 20 years
has given scientists remarkable opportunities to understand the
molecular basis of how a cell functions, not only in disease, but in
everyday activities as well. Using these techniques, scientists have
mapped out the genetic molecules, or genes, that control many life
processes in common microorganisms. Continued improvement of
these biotechniques has allowed researchers to begin to develop
maps of human chromosomes, which contain many more times the
amount of genetic information than those of microorganisms. Though
still somewhat crude, these maps have led to the discovery of some
important genes.
Unit 7 Biotechnology and Human Health
By the mid-1980s, rapid advances in chromosome mapping and other
DNA techniques led many scientists to consider mapping all 46
chromosomes in the very large human genome. Detailed, standardized
maps of all human chromosomes and knowledge about the nucleotide
sequence of human DNA will enable scientists to find and study the
genes involved in human diseases much more efficiently and rapidly
than has ever been possible. This new effort - the Human Genome
Project - is expected to take 15 years to complete and consists of two
major components. The first - creating maps of the 23 pairs of
chromosomes - should be completed in the first 5 to 10 years. The
second component - sequencing the DNA contained in all
Unit 7 Biotechnology and Human Health
the chromosomes - will probably require the full 15 years.
Although DNA sequencing technology has advanced rapidly over the past few years, it is still too slow and costly to use for sequencing even the amount of DNA contained in a single human chromosome. So while some genome project scientists are developing chromosome maps, others will be working to improve the efficiency and lower the cost of sequencing technology.
Why do the Human Genome Project?
Most inherited diseases are rare, but taken together; the more than 3,000 disorders known to result from single altered genes rob millions of healthy and productive lives. Today, little can be done to treat, let alone cure, most of these diseases. But having a gene in hand allows scientists to study its structure and characterize the molecular alterations, or mutations, which results in disease. Progress in
Unit 7 Biotechnology and Human Health
understanding the causes of cancer, for example, has taken a leap forward by the recent discovery of cancer genes. The goal of the Human Genome Project is to provide scientists with powerful new tools to help them clear the research hurdles that now keep them from understanding the molecular essence of other tragic and devastating illnesses, such as schizophrenia, alcoholism, Alzheimer’s disease, and manic depression.
Gene mutations probably play a role in many of today's most common diseases, such as heart disease, diabetes, immune system disorders, and birth defects. These diseases are believed to result from complex interactions between genes and environmental factors. When genes for diseases have been identified, scientists can study how specific environmental factors, such as food, drugs, or pollutants interact with those genes.
Unit 7 Biotechnology and Human Health
Finally, Human Genome Project research will help solve one of the
greatest mysteries of life: How does one fertilized egg "know" to
give rise to so many different specialized cells, such as those
making up muscles, brain, heart, eyes, skin, blood, and so on? For a
human being or any organism to develop normally, a specific gene
or sets of genes must be switched on in the right place in the body
at exactly the right moment in development.

Unit 7 Biotechnology and Human Health
The UV rays blasting down from the sun do more than burn your skin. They attack you right down to your DNA. That's why there's such a strong link between sun exposure and skin cancer.
If you could somehow repair the sun-damaged DNA in your skin, you could go a long way toward reducing your risk of skin cancer. As a bonus, your skin would look younger and healthier.
Every skin cell has a toolbox of enzymes that fix broken DNA, but what can you do when natural repairs aren’t enough? If you’re willing to reach into your wallet, you might be tempted to try a relatively pricey sunscreen or skin cream that contains DNA-repairing enzymes.
The Healthy Skeptic: How Effective are Skin Products with DNA-repairing Enzymes?
Unit 7 Biotechnology and Human Health
One option is a Neova DNA Damage Control sunscreen from PhotoMedex. Along with antioxidants, zinc oxide and other familiar ingredients, the sunscreens contain an enzyme called UV-endonuclease that’s harvested from an extract of ocean bacteria. This extract, called micrococcus lysate, is enclosed in a tiny package of fat (called a liposome) that supposedly helps deliver the enzyme deep into the skin. A 3-ounce tube of Neova Active (SPF 45) costs $46 on the company website. A 2.5-ounce tube of Neova Everyday (SPF 43) costs $39.
Unit 7 Biotechnology and Human Health
The claims
The Neova website says that "smart" sunscreens are the “newest, most powerful” therapy for sun-damaged skin. Barbara Hayes, vice president of marketing for PhotoMedex, says that the sunscreens will lighten age spots, reduce fine lines and even out skin tone within about four weeks. “It’s really quite amazing when you see someone who has used this product,” she says.
The DNA EGF Renewal website says that the products offer a “futuristic approach to skin renewal and protection.” Moy, the dermatologist who founded the company, says that many studies have shown that DNA-repairing enzymes in lotions and creams really can revitalize skin, reverse sun damage and reduce the risk of
Unit 7 Biotechnology and Human Health
skin cancer. He recommends the products for his patients at heightened risk for skin cancer, including those with very fair skin.
The bottom line
The idea that anything in a lotion could actually repair something as fragile and complicated as DNA may sound far-fetched, but DNA-repairing enzymes have a proven ability to heal and protect, says Dr. Steven Q. Wang, director of dermatologic surgery and dermatology at Memorial Sloan-Kettering Cancer Center in Basking Ridge, N.J.
Unit 7 Biotechnology and Human Health
In simple terms, endonucleases work by cutting out the damaged bits of DNA, which are then regenerated. Many studies in the last decade have shown that adding extra enzymes to the skin “enhances the body’s innate mechanisms for repairing DNA damage,” Wang says. For one example, a 2010 study in the Journal of Drugs in Dermatology by Moy and colleagues at UCLA found that using a cream with DNA repair enzymes for 48 weeks significantly reduced actinic keratoses (scaly precancerous growths) in 17 people with severely sun-damaged skin. (The product used in the study is not commercially available.)
Unit 7 Biotechnology and Human Health
But because Neova and similar products haven't been thoroughly tested in clinical trials, Wang says he has some questions about their real-world benefits. His main concern is that the products may not deliver enzymes deeply enough to have any noticeable effect on fine lines and age spots. “If you have money and want to try it, I say go for it,” he says. “But it may not be worth it.”

Moy, the dermatologist who founded the company, says that many studies have shown that DNA-repairing enzymes in lotions and creams really can revitalize skin, reverse sun damage and reduce the risk of skin cancer. (Para. 6)
句中由 who 引导的定语从句用来修士主句主语 Moy; 其次由that 引导宾语从句做主句谓语动词 says 的宾语;宾语从句中套嵌另一个由 that 引导的宾语从句做 shown 的宾语;而第二个从句则由名词短语做主语,由三个动词 revitalize, reverse, reduce并列做从句的谓语。此句的中文意思是 : 创办该公司的皮肤学家莫伊说很多研究都表明润肤露和乳霜里的 DNA 修复酶确实能使皮肤获得新生、修复皮肤损害、降低患皮肤癌的风险。

The idea that anything in a lotion could actually repair something as fragile and complicated as DNA may sound far-fetched, but DNA-repairing enzymes have a proven ability to heal and protect, says Dr. Steven Q. Wang, director of dermatologic surgery and dermatology at Memorial Sloan-Kettering Cancer Center in Basking Ridge, N.J. (Para. 7)
第一个分句中由 that 引导同位语从句修饰主语 idea ,谓语动词为sound;第二个分句是由转折连词引导的简单句,两个分句加在一起作为动词says 的直接引语。 says Dr. Steven Q. Wang 为倒装用法, 其后是名词短语加介词短语用来修饰主语 Dr. Steven Q. Wang 。 此句翻译时可以根据意群,按照汉语习惯重新划分句群。此句的中文意思是 : 认为润肤露里的某种成分真的能修复如 DNA般脆弱而复杂的东西听起来似乎不太经得起推敲。但据位于美国新泽西州 Basking Ridge 纪念斯隆 -凯特琳肿瘤中心的皮肤外科及皮肤医学主任史蒂夫 ·王博士说, DNA 修复酶在愈合和保护方面有明显的作用。

For one example, a 2010 study in the Journal of Drugs in Dermatology by Moy and colleagues at UCLA found that using a cream with DNA repair enzymes for 48 weeks significantly reduced actinic keratoses (scaly precancerous growths) in 17 people with severely sun-damaged skin. (Para. 8)
主句主语 study 为名词,主句谓语动词 found 后连接由 that引导的宾语从句;从句中由动名词短语做主语,从句谓语动词 reduced 。此句的中文意思是 : 比如, 2010年莫伊和他在加利福尼亚大学洛杉机分校的同事共同发表在 Journal of Drugs in Dermatology 上的一篇论文指出:在使用了含 DNA 修复酶的一种乳霜 48周后, 17 个皮肤被太阳严重损伤者光化性角化病(鳞屑癌前增长)有了明显改善。

Career Salon “People say it would be terrible if we made all
girls pretty. I think it would be great.” said James D.Watson, the head of the National Center for Human Genome Research at the NIH, who has suggested that beauty could be genetically engineered. He has also repeatedly supported genetic screening and genetic engineering in public lectures and interviews, arguing that stupidity is a disease and the "really stupid" bottom 10% of people should be cured.
