DNA replication Flashcards
1
Q
Who proved that DNA replication was semi-conservative?
A
Meselson-Stahl
2
Q
Describe DNA replication
A
DNA helicase binds to DNA and breaks the H bonds between the 2 strands
DNA helix helix unwinds and strands are separated
Free floating nucleotides form H bonds with the complementary bases
DNA polymerase forms phosphodiester bonds between the nucleotides
New DNA strands are synthesised
3
Q
Which strand is used as a template strand during DNA replication?
A
Both strands in DNA are used as template strands to produce complementary strands
4
Q
Which enzymes are used in DNA replication?
A
DNA helicase
DNA polymerase
