5.2 SG

Question 1

Define DNA replication

Answer 1

A process by which DNA is replicated and new strands of DNA are made from an old strand and a new strand

Question 2

Why does DNA replication happen?

Answer 2

To grow, repair, and reproduce

Question 3

How many types of Replication are there?

Answer 3

3: Conservative, semiconservative, and dispersive

Question 4

Define conservative replication

Answer 4

Replication in which the copy is an exact copy and is the same

Question 5

Define semiconservative replication

Answer 5

Strands made by combination of 2 different strands

Question 6

Define dispersive replication

Answer 6

New strands of NDA made from bits and fragments of two different strands of DNA

Question 7

What does the Helicase do?

Answer 7

It “unzips” the double helix, separating the 2 strands of DNA

Question 8

What does the Primer do?

Answer 8

It places RNA primers on the strand of DNA so that the DNA polymerase knows where to work

Question 9

What does the DNA polymerase 3 do?

Answer 9

It builds new strands of DNA by placing new Nucleotides and matching them to their appropriate nitrogenous base pair as well

Question 10

From which end can the DNA polymerase work?

Answer 10

It can only add onto 3’ ends so it’ll start at the 5’ end towards the other

Question 11

What does the Ligase do?

Answer 11

It seals the gaps made between the strands of DNA made by the Lagging line since it has to begin and cease the process multiple times
