More DNA

Question 1

Define Lagging Strand

Answer 1

Requires a slight delay before undergoing replication, and it must undergo replication discontinuously in small fragments.

Question 2

Define Leading Strand

Answer 2

Continuously synthesized strand of DNA.

Question 3

Define Semi-discontinuous

Answer 3

Synthesized in fragments as opposed to a continuous singular segment

Question 4

Define Semiconservative replication

Answer 4

The form of replication that DNA uses by splitting itself into 2 singular strands and proceeding to add more nucleotides onto that to make 2 double helixes.

Question 5

Define Okazaki fragments

Answer 5

Short DNA pieces as result of the lagging strand discontinuously synthesizing DNA

Question 6

What is the function of Helicase?

Answer 6

To split and unwind the double helix of DNA.

Question 7

What is the function of Primase?

Answer 7

To add nucleotide primers to the unwound strand.

Question 8

What is the function of DNA Polymerase III?

Answer 8

To add the actual nucleotides to the strand.

Question 9

What is the function of DNA Polymerase I?

Answer 9

To replace the primers with real nucleotides.

Question 10

What is the function of Ligase?

Answer 10

To double check the work of the polymerases.
