DNA replication

Question 1

Why is DNA replicated

Answer 1

for cell division, so that an identicle copy of the DNA can be placed in each daughter cell

Question 2

Step 1 of DNA replication

Answer 2

DNA helicase unzips the DNA helix by breaking the hydrogen bonds

Question 3

Step 2 of DNA replication

Answer 3

The free nucleotides in the nucleoplasm form hydrogen bonds with their complementary base pairings

Question 4

Step 3 of DNA replication

Answer 4

DNA polymerase enzyme joins the nucleotides to eachother using strong phosphodiester bonds to create the sugar phosphate backbone

Question 5

What direction does DNA polymerase move

Answer 5

5’-3’ direction

Question 6

Step 4 of DNA replication

Answer 6

-Another enzyme winds the two new strands to form double helixes
-Each new call now contains one original strand and one new one

Question 7

How do you speed up DNA replication

Answer 7

-By making the DNA replication simultaniously happen on many sites along the DNA
-This creates replication forks
