Which of the following is most accurate about DNA replication
and transcription/translation (central dogma)?
Select one:
a. DNA replication and transcription/translation produce the
same molecules.
b. DNA replication occurs in some cells, while
transcription/translation occurs in virtually all cells.
c. The same enzyme is responsible for DNA replication and
transcription/translation.
d. DNA replication occurs in virtually all cells, while
transcription/translation occurs in some cells.
e. DNA replication occurs in somatic cells while
transcription/translation occurs only in gametes.
For each of the following sequences, state which process, DNA
replication, transcription, RNA processing, or translation, is
affected most directlyby deleting the sequence below. You should
chose only one process for each sequence. (Section 15.4)
a. ori site
b. 3' splice site
c. poly(A) tail
d. terminator
e. start codon
f. –10 consensus seq
g. Shine-Dalgarno
1. If a cell cannot properly create DNA polymerase which step of
replication would this cell be incapable of performing? Explain
why
2. It is possible to compare transcription to a race car moving
along a track. In transcription which units or structures would be
analogous to the following: the car, a green light, the track, and
a stop sign?
3. Describe the relationship between the sequence of the mRNA
molecule and the amino acid sequence of the resulting protein.
