replication

Subdecks (1)

phase of mitosis that involves DNA replication
interphase
what are the enzymes involved
gyrase
helicase
DNA polymerase
ligase
what is the first thing that must happen
the DNA must be 'untwisted'
what enzyme is involved with the first stage
DNA gyrase
what is the second stage involved with transcription
a replication fork must be formed
the hydrogen bonds between complementary base pairings must be broken
what is the enzyme involved with the second stage of transcription
helicase
what is the third stage of transcription
phosphodiester bonds must be formed between adjacent nucleotides
what is the enzyme involved with the third stage of transcription
DNA polymerase
what is the issue with the enzyme involved with the third stage
it works only in a 3' to 5' direction
what are the two different strands after the third stage called
leading strand and lagging strand
what does the third stage result in
Okazaki fragments from one strand
what is the enzyme involved with the fourth stage
ligase
what does the 4th enzyme do
forms phosphodiester bonds between fragments
what does this mean every strand of DNA is made from
one original strand and one new formed from fragments
what is this process known as
semi-conservative replication
