DNA and RNA Structure

Question 1

What is the complementary strand of this sequence?

Revolt · Accepted Answer

5’-CGAATCAT-3’

Question 2

The is made continuously because it is synthesized in the direction the replication fork is moving.

Revolt · Accepted Answer

Leading strand

Question 3

The is synthesized discontinuously because DNA polymerase must be moved to construct DNA in the 5’ to 3’ direction.

Revolt · Accepted Answer

Lagging strand

Question 4

Which concepts did you include in your answer? Check all that apply.

Revolt · Accepted Answer

Presence of chemical A prevents DNA replication.; Chemical A blocks helicase activity.; Chemical A inhibits DNA unwinding.; Absence of chemical A allows for DNA replication to occur normally.

Question 5

Which statement best describes why DNA is built in the 5’ to 3’ direction?

Revolt · Accepted Answer

DNA polymerase acts on the OH group of the existing strand to add nucleotides.

Question 6

The allows nucleotides to be added to the growing strands.

Revolt · Accepted Answer

Primer

Question 7

Which concepts did you include? Check all that apply.

Revolt · Accepted Answer

DNA polymerase proofreads the sequence.; Nuclease cuts the damaged daughter strand to remove T.; DNA polymerase adds C to form the correct pairing.; DNA ligase connects the backbones of the segments.
