RNA Review – Structure, Function & Protein Synthesis Study Guide
A mutation results in a defective enzyme a. Which of the following would be a consequence of
that mutation? - ANS ✔✔An accumulation of A and no production of B and C
Which of the following represents a similarity between RNA and DNA? - ANS ✔✔Nucleotides
consisting of a a phosphate, sugar, and nitrogen base
RNA differs from DNA in the RNA - ANS ✔✔Contains ribose as its sugar and contains uracil
instead of thymine
A particular triplet of bases in the coding sequence of DNA is AGT. The corresponding codon for
the mRNA transcribed is - ANS ✔✔UCA
Which of the following is correct about a codon? It - ANS ✔✔May code for the same amino acid
as another codon
Where is the attachment site for RNA polymerase? - ANS ✔✔Promoter Region
Which of the following is not involved in transcription? - ANS ✔✔Initiation Factors
Which of the following helps to stabilize mRNA by inhibiting it's degradation? - ANS ✔✔Poly(A)
tail
What are the coding segments of a stretch of eukaryotic DNA called? - ANS ✔✔Exons
As a ribosome translocation along an mRNA molecule by one codon, which of the following
occurs? - ANS ✔✔The tRNA that was in the A site moves into the P site and the tRNA that was
in the P site moves to the E site and is released
