The leading strand requires # of RNA primers, and the
lagging strand requires # of RNA primers. - CORRECT
ANSWER-One; more than one
What replaces RNA nucleotides with DNA nucleotides in a
newly synthesized strand? - CORRECT ANSWER-DNA
Polymerase
Mismatch repair is the process of identifying nucleotides
that are inappropriately matched, such as guanine with a
thymine, and removes the incorrect nucleotide from the
newly synthesized strand (t/f) - CORRECT ANSWER-True
,Nucleotide excision repair (cutting DNA) is accomplished by
what enzyme? - CORRECT ANSWER-Nucleases
Telomeres contain a large proportion of vital coding DNA (T/F)
- CORRECT ANSWER-False
What cells of the body are shielded from telomere shortening? -
CORRECT ANSWER-Germ cells Telomeraseactivity in somatic
cells has implications for: - CORRECT ANSWER-Cancer
Gene - CORRECT ANSWER-Unit of hereditary composed of
DNA; passed from parent to offspring
Genotype - CORRECT ANSWER-Sequence of genetic
information
Phenotype - CORRECT ANSWER-Observable characteristics
resulting from genotype.
, Transcription - CORRECT ANSWER-the process of
synthesizing mRNA from a DNA template
Transcription - CORRECT ANSWER-Process of interpreting
mRNA to sequence of amino acids/proteins
RA class of DNA polymerase patrols newly added nucleotides
and will remove nucleotides that are erroneous. How does the
polymerase "know" a nucleotide is misplaced. - CORRECT
ANSWER-Newly adde nucleotides are compared to the
complimentary template strand.
Replication of DNA begins at a single origin of replication
and then proceeds the entire length of the strand, in one
direction (T/F) - CORRECT ANSWER-False
