Unfortunately, science is a complex subject

Unfortunately, science is a complex subject

It does require learning a lot of facts

Remember science last year? What you get in school (from 1st grade to 4th year of college) is a recitation of what science has found out.

In essence, you learn the history of science.

In the 21st century our ability to manipulate biology will require the public to make momentous decisions.

These decisions should be made from an informed point of view.

Why molecular Genetics?Why molecular Genetics?

Foundation of all the biological sciences.

An understanding of genes is central to an understanding of all biology.

All of the various facts that seem to be unrelated in biology can be woven into a coherent whole with molecular genetics as the unifying concept.

Connecting diverse branches of biology with

molecular genetics

Connecting diverse branches of biology with

molecular genetics Developmental biology-Ultimately is the study of what genes are turned on and what genes are turned off (gene regulation).

Physiology and morphology-Ultimately is the study of what proteins are expressed by genes.

Ecology-Ultimately is the study of genetic changes that allow for adaptation to the environment

Evolution-Ultimately is the study of change in gene frequency in a population over time.

Taxonomy-Ultimately is the study of genetic differences and similarities between species.

Definition of molecular genetics

Definition of molecular genetics

The study of the biological molecules that pass information from generation to generation.

It involves the study of the structure and activity of the genetic material at the molecule level.

The major biological molecules involved are DNA and proteins.

Structure of genetic material

Structure of genetic material

Chromosome-is the structure that contains the genetic material that is passed from generation to generation.

Consists of one long DNA molecule and proteins.

Relationship between chromosome,DNA, and geneRelationship between

chromosome,DNA, and gene Chromosome-structure within

cell that contains the genetic material as threadlike DNA surrounded by proteins

DNA-A nucleic acid molecule that contains the genetic information.

Gene-Segment of DNA (on a specific site on a chromosome) that is responsible for the physical and inheritable characteristics (trait) of an organism usually by specifying a protein.
