GENETICS/DNA/DNA Structure/screen 3
The variability in the DNA molecules is a result of variation in the sugar phosphate bonds along the sides of the ladder. Is this statement true or false?
GENETICS/DNA/DNA Structure/screen 6
The function of the histone proteins is to wrap around the DNA and protect it from being mutated by radiation. True or False?
GENETICS/DNA/DNA replication/screen 2
DNA ligase is more important in the replication of the lagging strand than it is in the leading strand. Explain.
GENETICS/DNA/DNA replication/screen 4
When a strand of the DNA molecule is damaged by radiation it can be repaired using the undamaged strand as a template. True of False?
GENETICS/Protein Synthesis/Transcription/screen 2
What is the function of the promoter site on a DNA molecule and how many would you expect to find on a DNA molecule?
GENETICS/Protein Synthesis/Translation/screen 4
A tRNA molecule called a release factor carries no amino acid but it binds to the A site of a ribosome, what is it's function?
GENETICS/Protein Synthesis/Translation/screen 7
A polysome is a group of ribosomes clustered along a
a) DNA molecule, b) messenger RNA, c) protein, d) transfer RNA.
GENETICS/Protein Synthesis/Translation/screen 9
Base substitution, deletion, and insertion are all mutations. Which of these would you expect to have the least effect on the protein that is synthesized from this codon?
GENETICS/Protein Synthesis/Gene regulation/screen 3
An inducible enzyme is a useful adaptation because:
a) the messenger RNA for the enzyme will only be transcribed if the enzyme's substrate binds with the operon's repressor.
b) it's product prevents too much of the enzyme from being produced by binding with and activating the repressor of the operon.
GENETICS/Protein Synthesis/Gene regulation/screen 4
A repressible enzyme is a useful adaptation because:
a) the messenger RNA for the enzyme will only be transcribed if the enzyme's substrate binds with operons' repressor.
b) it's product prevents too much of the enzyme's messenger RNA from being produced by binding with and activating the repressor of the operon.
