DNA replication Flashcards
1
Q
First step to DNA replication
A
DNA unzips- DNA is catalysed by DNA helicase and results in two strands with exposed nucleotide bases
2
Q
Second step to DNA replication
A
Free nucleotides in the nucleoplasm bind to the exposed strands with the help of DNA polymerase. which catalyses the nucleotides in the 5’ to 3’ direction.
3
Q
what does primase do?
A
primase makes primer out of RNA so DNA polymerase knows where to start.
4
Q
Third step to DNA replication
A
5
Q
What is semi conservative replication?
A
when each of the two DNA molecule after replication contain one of the original strand and a copy.
