Question
Chapter 33, Problem 11P
Interpretation Introduction
Interpretation:
The effect of the addition of IRE to the 5’ end and 3’ end of mRNA should be determined.
Concept introduction:
IRE (iron response element) is a conserved stem-loop structure which is bound to IRP (iron response proteins). The untranslated regions (UTRs) of mRNAs are bound to IRE. The products of UTRs are involved in iron

An extra piece. In one type of mutation leading to a form of
thalassemia, the mutation of a single base (G to A) generates a new 3'
3' splice site (blue in the illustration below) akin to the normal one
(yellow) but farther upstream.

What is the amino acid sequence of the extra segment of protein
synthesized in a thalassemic patient having a mutation leading to
aberrant splicing? The reading frame after the splice site begins with
TCT.

Polymerase inhibition. Cordycepin inhibits poly(A) synthesis at low
concentrations and RNA synthesis at higher concentrations.

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?
