Textbook Question
Chapter 18, Problem 18.8PS
RNA Processing. The three major classes of RNA found in the cytoplasm of a typical eukaryotic cell are rRNA, tRNA, and mRNA. For each, indicate the following:
(a) Two or more kinds of processing that the RNA has almost certainly been subjected to
(b) A processing event unique to that RNA species
(c) A processing event that you would also expect to find for the same species of RNA from a bacterial cell

Students have asked these similar questions
True or False. Explain.
A) At no time during protein synthesis does an amino acid make direct
contact with the mRNA being translated.
B) Because the two strands of DNA are complementary, the mRNA of a gene can be synthesized using either strand as a template.
Leaderless. The MRNA for the A repressor begins with 5'-AUG-3',
5'-AUG-3', which encodes the methionine residue that begins the
protein. What is unusual about this beginning? Would it cause the
MRNA to translate efficiently or not?
Polymerase inhibition. Cordycepin inhibits poly(A) synthesis at low
concentrations and RNA synthesis at higher concentrations.
NH2
H.
он
Cordycepin (3'-deoxyadenosine)
a. What is the basis of inhibition by cordycepin?
b. Why is poly(A) synthesis more sensitive than the synthesis of other
RNAS to the presence of cordycepin?
c. Does cordycepin need to be modified to exert its effect?
