Question

In the figure below, which depicts the activation step in bacterial DNA replication, the letter Q points to ________, and the letters R and S point to ________, respectively. 
A) DnaA-ATP proteins; 9-mer repeats within oriC and 13-mer sequences 
B) Primase; oriC and 13-mer repeats 
C) SeqA protein; 13-mer repeats and 9-mer basepairs within oriC 
D) DamA methylase; 9-mer repeats within oriC and 13-mer repeats 
E) gyrase; 13-mer repeats and 9-mer sequences within oriC

Quizplus · Accepted Answer

Q points to DnaA-ATP proteins, which are responsible for initiating the unwinding of DNA at the oriC (origin of replication) site. R and S point to the specific sequences within oriC - R points to the 9-mer repeats and S points to the 13-mer sequences.
