Question 1

leading strand

Answer 1

the strand of nascent DNA which is synthesized in the same direction as the growing replication fork

Question 2

lagging strand

Answer 2

A lagging strand requires a slight delay before undergoing replication, and it must undergo replication discontinuously in small fragments.

Question 3

semi-discontinous

Answer 3

A mode of DNA replication in which one new strand is synthesized continuously,

Question 4

Semiconservative replication

Answer 4

produce two copies that each contained one of the original strands of DNA and one new strand.

Question 5

Okazaki fragments

Question 6

DNA enzyme functions

Answer 6

Helicase
-unwinds and separates the double-stranded DNA by breaking hydrogen bonds between base pairs
Primase
-Adds RNA primers needed b/c DNA polymerase lll can only add new nucleotides to an existing strand
DNA Polymerase III
-added new nucleotides to build new DNA strands
DNA Polymerase I
-Removed RNA primers and replaces with DNA nucleotides
Ligase
-Puts DNA strand built in fragments together
