Chapter 16 Flashcards
1
Q
Helicase
A
Unwinds DNA, separates 2 strands
2
Q
Primase
A
puts down RNA primer to start replication
3
Q
DNA polymerase III
A
adds nucleotides in 5 to 3 direction on the leading strand. Binds to primer on the lagging strand.
4
Q
Leading Strand
A
replicates continuously
5
Q
Lagging Strand
A
- Replicates discontinuously
- requires primer
- replicates in small fragments called Okazaki fragments
6
Q
DNA polymerase l
A
replaces RNA primers with DNA
7
Q
DNA ligase
A
seals fragments together
8
Q
Okazaki Fragments
A
Short segments of DNA that grows 5 to 3 that are added onto the lagging strand.
9
Q
Telomeres
A
repeated units of short nucleotide sequences at the ends of DNA.
10
Q
Telomerase
A
enzyme that adds to telomeres
