ExpressYourself
Glucose is to glycogen, as ___________ is to DNA.
nucleotide
Specifically, what are the three parts to DNA nucleotide?
Deoxyribose, phosphate, nitrogenous base
Cytosine and Thymine have a single ring and are known as this.
pyramidine
The 5’ end and 3’ end refer to what part of the 5 carbon sugar?
Carbon 5 at top and carbon 3 at the bottom
These two scientists figured out that DNA carries genetic
information, whereas proteins do not.
Hershey and Chase
Helicase breaks these bonds between these molecules.
Hydrogen, nitrogenous bases
This enzyme glues Okazaki fragments together.
Ligase
This enzyme lays down a short segment of RNA in order to start
replication.
Primase
This term refers to how replication uses a template
strand; and therefore, the new DNA consists of only one newly
synthesized strand per double helix.
Semi- conservative
This enzyme digests and replaces the RNA primer with DNA
DNA Polymerase
These are the three kinds of RNA
mRNA, tRNA, rRNA
These two things are is RNA, but not DNA
Ribose, uracil
This molecule is made from DNA, and read by ribosomes.
mRNA
This part of the ribosome is where the tRNA enters bringing its corresponding amino acid
A site
From 5’ to 3’, what is the mRNA sequence that corresponds to the
DNA strand:5’ ATACCGAAT 3’
AUUCGGUAU
(had to flip it!!!)
This is a change in the genetic code at a single nucleotide.
Point mutation
In thinking about protein synthesis, this is the least harmful point
mutation.
Substitution
These three mutations involve chromosomal breakage.
Inversion, Deletion, translocation
If a cell was doubly fertilized (by two sperm), this would be the term
to describe its chromosomes
Triploid, or polyploid
How are mutations linked to evolution?
Mutations are the ultimate source of genetic variation. If something is a beneficial mutation, it may increase over time in the population (change
over time).
When a genes is expressed, this means what two processes are
occurring?
It is being transcribed and translated.
Gene expression in prokaryotes can be halted by this.
Repressor
This region of an operon allows transcription to continue.
Operator
These genes in eukaryotes code for specific body arrangement.
Hox genes
_______________ breaks lactose into galactose and glucose in
prokaryotes, and ____________ breaks lactose into glucose and
galactose in eukaryotes.
β-Galactosidase breaks lactose into galactose and glucose in
prokaryotes, and Lactase breaks lactose into glucose and galactose in
eukaryotes.
