DNA Translation Flashcards
1
Q
Goal of translation
A
To translate codons into amino acids
2
Q
Second step in gene exoression
A
Translation
3
Q
RNA to protein
A
Translation
4
Q
Where does translation occur
A
Ribosomes
5
Q
assists mRNA to know where it should land
A
rRNA
6
Q
How many amino acids per protein
A
20
7
Q
A cell translates an mRNA message into protein with the help of
A
tRNA
8
Q
Carries out equivalent translation (amino acid)
A
tRNA
9
Q
start codon
A
AUG
10
Q
stop codon
A
UAG, UGA, UAA
11
Q
Process of translation
A
- Initiation
- Elongation
- Termination
12
Q
Initiation of Translation
A
- AUG signals start
- small ribosomal subunit binds w mRNA and slecial initiator RNA
- Initiation factors bring large subunit that completes translation initiation complex
13
Q
Protein present in initiation process
A
Initiation Factors
14
Q
Elongation of Translation
A
- Amino acids are added one by one
- Each addition involves protein called elongation factors
15
Q
Holds the tRNA that carries the growing polypeptide chain
A
P Site
16
Q
Holds tRNA which carries the next amino acid to be added to the chain
A
A Site
17
Q
Site where discharged tRNAs leave the ribosome
A
E site
18
Q
Termination of Translation
A
- A site accepts release factor once stop codon was read
- Addition of water molecule
- Reaction causes the release of polypeptide
19
Q
A
