1
Q
What do mutations increase?
A
- increase diversity
2
Q
What are ribosomes
A
- site of protein synthesis
3
Q
what do ribosomes”sandwhich”?
A
- the MRNA strand to bring MRNA, TRNA and enzymes required to build polypeptides
4
Q
where do you find anticodons?
A
- on the opposite end of each TRNA Molecule
5
Q
what is TRNA?
A
-“ transfer” RNA
- brings the correct aminoacid
6
Q
how does TRNA know which amino acid to bring
A
- because of the anti-codon
7
Q
When does translation happen?
A
- later
8
Q
what happens in translation?
A
- translates the MRNA into proteins
9
Q
What is built during translation?
A
- a polypeptide chain from amino ands
10
Q
What does RNA polymerase add in transcription?
A
- adds complementary nucleotides to template DNA Strand
11
Q
what does transcription produce?
A
- produces a single strand of MRNA that is ready to exit the nucleus
12
Q
What is translation carried out by?
A
- ribosomes
13
Q
what are the 3 processes in transcription?
A
- initiation
- elongation
- termination
14
Q
What process happens in transcription?
A
- turns DNA into MRNA in the nucleus
15
Q
What happens in initiation during transcription?
A
- polymerase binds to promoter sequence
