DNA Flashcards
1
Q
What does a dispersed replication look like
A
Two original strands > 4 strands all containing 50/50 new/old deoxyribose
2
Q
What does a conserved replication look like
A
Two DNA strands > the two old strands and two new ones
3
Q
What does a semi- conservative replication look like
A
Two old DNA strands > 1 old 1 new-1 old 1new
4
Q
How is DNA replicated
A
DNA Helicase unzips the two strands
By breaking hydrogen bonds between bases
Free nucleotides that are activated join to complimentary bases
They attach together using DNA polymerase causing phosphodiester bonds between the phosphate and the sugar
5
Q
What does DNA ligase join
A
It joins Okazaki fragments
