GCD QUIZ 6 REVIEW TEST BANK
QUESTIONS WITH ALL CORRECT
ANSWERS
How many replication forks are formed at an origin of replication?
One
Two
Four
Many - Answer-Two
DNA polymerase is not able to do which of the following?
synthesize DNA in the 5' to 3' direction
synthesize DNA in the 3' to 5' direction
synthesize DNA on a bare template strand
both b and c - Answer-both b and c
In the leading strand, DNA is made in the direction the replication fork and is
made as .
toward, one continuous strand
away from, one continuous strand
toward, Okazaki fragments
away from, Okazaki fragments - Answer-toward, one continuous strand
The question is about the function of DNA ligase. The drawing below shows the
synthesis of the lagging strand. The top (purple) strand is the template DNA. The RNA
primers are red and the DNA is blue.
After DNA polymerase removes the middle RNA primer and fills in with DNA, where
does DNA ligase function? See the arrows on either side of the middle RNA primer.
Where is DNA ligase needed?
