The Stages of DNA Replication Flashcards
1
Q
What is the 1st step of DNA replication?
A
The DNA double-helix is unwound using the enzyme DNA polymerase and hydrogen bonds between bases are broken,separating the 2 strands
2
Q
What is the 2nd step of DNA replication?
A
A primer joins to the 3’ end of a 3’-5’ leading strand
3
Q
What is the 3rd step to DNA replication?
A
The enzyme DNA polymerase adds free DNA nucleotides to synthesise a complementary strand continuously
4
Q
What is the 4th step of DNA replication?
A
Primers are added on the lagging strand one by one
5
Q
What is the 5th step of DNA replication?
A
DNA is then added to the strand in the form of fragments
6
Q
What is the 6th step of DNA replication?
A
The fragments are then joined together by the enzyme DNA ligase to form a complete complementary strand
