EXAM!!!
A sequence of three RNA bases can function as a(n)
what?
(A) codon only
(B) anticodon only
(C) gene only
(D) codon or anticodon
(E) NONE of the above answers - Answer-(D) codon or
anticodon
What is Messenger RNA (mRNA)?
(A) a nucleic acid that, by itself, codes for the primary
structure of a protein.
(B) made directly from DNA during transcription.
(C) permanently incorporated into the structure of
ribosomes.
(D) larger if the protein to be made has a longer amino
acid sequence.

(E) NONE of the above answers - Answer-(B) made
directly from DNA during transcription.
The genetic material of some viruses, such as HIV, is not
normal DNA but is instead what component?
(A) RNA.
(B) protein.
(C) carbohydrate.
(D) lipid.
(E) single-stranded DNA. - Answer-(A) RNA.
In a wild-type strain of fruit flies, the length of a gene from
the start to the stop codon is 2,000 DNA bases. Suppose
an experiment indicated that the mRNA molecule
transcribed from this gene is much shorter (only 1,200
bases). What is the most likely explanation for this?
(A) A mutation caused the formation of an extra stop
codon in the gene.
(B) The mRNA was prematurely degraded.
(C) There are introns in the DNA that were cut out of the
mRNA.

(D) The first 800 bases of DNA are always lost as it is
transcribed into mRNA. (E) NONE of the above answers -
Answer-(C) There are introns in the DNA that were cut out
of the mRNA.
What does the process of Transcription do?
(A) synthesizing a DNA molecule from an RNA template.
(B) assembling an RNA molecule without a template.
(C) synthesizing an RNA molecule using a DNA template.
(D) synthesizing a protein using information from mRNA.
(E) replicating a single-stranded DNA molecule. - Answer-
(C) synthesizing an RNA molecule using a DNA template.
What is the process of converting the "message" of mRNA
into a sequence of amino acids called?
(A) translation.
(B) transcription.
(C) activation.
(D) replication.
(E) repression - Answer-(A) translation.
