1.3. CHEMISTRY &SYNTHESIS OF DNA Flashcards
1
Q
AMP
A
Adenosine monophosphate
2
Q
ADP
A
Adenosine diphosphate
3
Q
ATP
A
Adenosine triphosphate
4
Q
Semi-conservative replication
A
New and old strand of DNA present in 2 molecules of DNA formed
5
Q
Helicase
A
Unwinds dsDNA (breaks hydrogen bonds between two strands)
6
Q
Single-stranded DNA binding proteins
A
Bonds single stranded DNA preventing unwound strands from joining
7
Q
Topoisomerase
A
Prevents supercoiling of DNA as strands unwind
8
Q
Primase
A
Synthesizes a short RNA primer required for DNA polymerization
9
Q
DNA polymerase
A
Synthesizes daughter strands from parental strands (5’ to 3’ direction)
-> phosphodiester bond formation
10
Q
DNA ligase
A
Joins (ligates) Okazaki fragments together to form the lagging strand
- phosphodiester bond formation
