STUDY GUIDE PRACTICE QUESTIONS WITH
CORRECT ANSWERS 2026/2027 LATEST
A class of DNA polymerase patrols newly added nucleotides
and will remove nucleotides that are erroneous. How does the
polymerase "know" a nucleotide is misplaced. ✔✔✔✔Newly
adde nucleotides are compared to the complimentary template
strand.
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) ✔✔✔✔True
Page 1 of 16
,Nucleotide excision repair (cutting DNA) is accomplished by
what enzyme? ✔✔✔✔Nucleases
Telomeres contain a large proportion of vital coding DNA (T/F)
✔✔✔✔False
What cells of the body are shielded from telomere shortening?
✔✔✔✔Germ cells
Telomerase activity in somatic cells has implications for:
✔✔✔✔Cancer
Gene ✔✔✔✔Unit of hereditary composed of DNA; passed from
parent to offspring
Genotype ✔✔✔✔Sequence of genetic information
Page 2 of 16
, Phenotype ✔✔✔✔Observable characteristics resulting from
genotype.
Transcription ✔✔✔✔the process of synthesizing mRNA from a
DNA template
Transcription ✔✔✔✔Process of interpreting mRNA to sequence
of amino acids/proteins
# of bases encode for # of different amino acids
✔✔✔✔4; 20
is read in a triple codon reading frame ✔✔✔✔mRNA
The TATA box is necessary for initiation of transcription and is
located on the DNA strand (t/f) ✔✔✔✔True
