💙 Unit 4: Protein Synthesis - Translation Flashcards
1
Q
Translation
A
mRNA —-> Protein
2
Q
Where does translation occur?
A
Cytoplasm
3
Q
Codon
A
- Sequence of every three nucleotides in DNA or RNA
- Binds to tRNA anticodon
4
Q
Anticodon
A
- Sequence of every three nucleotides in tRNA
- Codes for specific amino acid
- Binds to mRNA codon
5
Q
What is always the first/start codon?
A
AUG
6
Q
What is always the starting amino acid?
A
Methionine (Met)
7
Q
Translation Process (1)
A
mRNA binds to small ribosomal unit
8
Q
Translation Process (2)
A
tRNA binds to the mRNA and small ribosomal unit with Methionine
9
Q
Translation Process (3)
A
larger ribosomal unit and second tRNA attaches to codon
10
Q
Translation Process (4)
A
peptide bond is broken between 1st and 2nd amino acid as next codon comes in
11
Q
Translation Process (5)
A
repeats until stop codon (UAA) is reached
12
Q
What happens when translation is over?
A
ribosomal units detach and proteins can take on its secondary and tertiary structures.
