7. once DNA synthesis is complete along the template, the

Answer 1

RNA primers must be removed and replaces by DNA nucleotides

The RNA primers are
removed by DNA
polymerase 1
proofreading after the
synthesis step

Question 2

8. Okazaki fragments are sealed together by

Answer 2

DNA ligase to form a continous piece of DNA (no RNA nucleotides)

Each chromosome now
has one single strand of
parental DNA (
