Molecular Genetics-3️⃣Translation Flashcards
1
Q
Translation
What is a Ribosome?
A
- Synthesized protein
- Translates the mRNA into a polypeptide (amino acid bonds)
- Recognizes 5’ cap for binding to eukaryotic mRNA
2
Q
Translation
What sites does the ribosome have for tRNAs?
A
FROM RIGHT TO LEFT ON DIAGRAM
1. A (acceptor site)
2. P (peptide site)
3. E (exit site)
anticodon & codon are below P site, small ribosome unit is underneath.

Q
Translation
What is The Process For Stage 1: Initiation
A
- Small ribosomal subunit + mRNA join with tRNA carrying start codon (met). Complex scans until anti codon is found.
4
Q
What is The Process For Stage 2: Elongation
A
- A Reading frame occurs:mRNA is read one codon at a time, and the amino acid matching each codon is added to a growing protein chain. if not done correctly, frameshift occurs.
