Replication Flashcards
1
Q
Why only 5’-3’ ends?
A
Polymerase = enzyme
Specific
Only complimentary and binds to 5’ end
Only complimentary with phosphate end
2
Q
DNA must
A
Replicate
3
Q
Double helix?
A
Unwinds
4
Q
Exposed bases?
A
Bind to free nucleotides
5
Q
Polymerase?
A
Binds complimentary base nucleotides
6
Q
Helicase
A
Splits/ separates strand
7
Q
Replication is
A
Semi conservative
8
Q
Protein synthesis
A
DNA codes for protein
A copy of DNA = mRNA. is made by transcription
mRNA used to make protein in the cytoplasm
9
Q
Transcription
A
DNA polymerase unwinds DNA
Free nucleotides join
RNA polymerase links adjacent nucleotides
mRNA moves out
10
Q
Translation1
A
mRNA binds to ribosome
tRNA carried amino acid to ribosome
11
Q
Translation2
A
2nd tRNA brings another AA
AAs bind
Repeats process
12
Q
Translation3
A
Polypeptide chain forms
Stop codon reached
