Question
Chapter 7, Problem 3MCQ
Summary Introduction
Introduction:
mRNA is formed by copying the DNA sequence, and the process is known as transcription. This process occurs in three steps which are initiation, elongation, and termination. After these steps, the complementary RNA molecule is formed.

What is the correct tRNA anti-codon sequence for the AUG mRNA sequences?
a. UGA
b. UAC
c. CAU
d. AUG
Choose the DNA sequence from which this mRNA sequence wastranscribed: 5′-AUACGAUUA-3′.a. 3′-TATGCTAAT-5′ c. 3′-UAUCGUAAU-5′b. 3′-UTUGCUTTU-5′ d. 3′-CTCAGCTTC-5′
Use the pre-mRNA sequence shown below to answer
the following questions.
MRNA: 5'ACUGGACAGGUAAGAAUACAACACAGUCGGCACCACG 3'
a. Underline the 5' and 3' splice sites, then write the
sequence of the spliced mRNA in the space provided.
b. Predict what would happen if the G in the 5' splice
site were mutated to a C.
c. We learned in this topic that the 5' cap in an mRNA
plays a role in translation initiation. What do you think
is one plausible mechanism by which a 5' cap can
enhance initiation ? How can you experimentally
demonstrate that a 5' cap is important for this process
?
