Question 1 Not yet graded / 4 pts
Fill-in-the-Blank: ________ is an enzyme that facilitates synthesis of an
RNA primer by using the unwound DNA strand as a template.
Your Answer:
primase
Answer: Primase (See section 1.1 in module)
Question 2 Not yet graded / 4 pts
What are RNA polymerases? How many types are found in eukaryotes?
, Your Answer:
family of enzymes responsible for separating the DNA strands and
chemically adding the RNA that complements it
3 types found in eukaryotes
Answer: RNA polymerases are a family of enzymes that are
responsible for separating the DNA strands and chemically
joining together complementary RNA nucleotides that are
added along the length of the template DNA strand. There are
three different RNA polymerases in eukaryotes, each of which
transcribes a different class of genes (See section 1.4 in
module).
Question 3 Not yet graded / 4 pts
What is the purpose of the reading frame during transcription?
Your Answer:
this is the key to correctly read the triplet code
Answer: The reading frame is the phase in which successive
nucleotides form codons and is typically designated by the
“start” (AUG) codon. Essentially, the reading frame ensures
that codons are processed correctly and that the cell reads
the nucleotides as non-overlapping triplets (See section 1.3 in
module).
