Question 1

DNA replication

Answer 1

The copying of double stranded DNA and necessary for cell reproduction prior to cell division 

Question 2

What is semi conservative?

Answer 2

The resulting DNA copies, each have one strand of parental DNA, and one newly constructed strand

Question 3

Helicase

Answer 3

Separates DNA strands

Question 4

SSB

Answer 4

Single strand binding proteins, or SSPs, are tetramers that coat the DNA this prevents the DNA strands from reannealing to form double stranded, DNA 

Question 5

Primase

Answer 5

Creates RNA primers

Question 6

Polymerase

Answer 6

Strings nucleotides together to form a DNA strand 
(Extends DNA chain)

Question 7

Sliding clamp

Answer 7

proteins that helps hold the DNA polymerase onto the DNA strand during replication 

Question 8

RNase H

Answer 8

removes the RNA primers that previously began the DNA strand synthesis 

Question 9

Ligase

Answer 9

Links short stretches of DNA together to create one long, continuous DNA strand

Question 10

Steps of DNA replication

Answer 10

1. Strands are separated
2. SSBs coat single strands
3. Primaries synthesizes RNA primers. 
4. Polymerase attaches nucleotide at three prime, end
   Synthesis begins in the 5 to 3 direction
5. One strand synthesizes continuously, while the lagging strand synthesizes Discontinuously 
6. RN, ace H removes RNA primers.
7. DNA polymerase I fills the gaps where RNA primers were removed 

Question 11

DNA pieces separated by RNA primers in lagging strand are called

Answer 11

Okazaki fragments

Question 12



Question 13

Why is primase necessary

Answer 13

Polymerase can only extend a nucleotide chain and not start one. Primates uses the original DNA as a template to create a short and RNA primer
