BIOD 102 REAL EXAM -ESSENTIAL
BIOLOGY II COMPLETE QUESTIONS
2025-2026 WITH DETAILED ANSWERS
ALREADY GRADED A+
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
What enzyme is responsible for relieving the stress
associated with the twisting and untwisting of a DNA
strand
during replication. - CORRECT ANSWER-Topoisomerase
As a replicated DNA strand elongates, what enzyme is
responsible for adding nucleotides? - CORRECT ANSWER-
DNA polymerase
The energy required to add a nucleotide to a growing
chain is
supplied by an exergonic reaction involving the hydrolysis
of
the nucleotide's pyrophosphate tail (T/F) - CORRECT
ANSWER-True
During elongation, in which direction are new nucleotides
being added to the leading strand? - CORRECT ANSWER-
5'
, —> 3'
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
