1
Q
Semi-Conservative replication
A
Half of the parental molecule is saved in each daughter molecule. 50%
2
Q
Helicase
A
Unzips the gene
3
Q
The point where the splitting starts is the
A
Replication Fork
4
Q
Top strand
A
Leading Strand 5’—>3’
5
Q
Bottom Strand
A
Lagging Strand 3’—>5’
6
Q
DNA Polymerase
A
Adds nucleotides only to the 3’ end of the stand never the 5’ end
7
Q
DNA Ligase(Speeds up or Catalyze the elongation of a new DNA Strand)
A
Seal breaks in the phosphate-sugar backbone of DNA and RNA.
8
Q
RNA primers
A
serves as a starting point for DNA polymerase
