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

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.

Translation

What is The Process For Stage 1: Initiation

A
  1. Small ribosomal subunit + mRNA join with tRNA carrying start codon (met). Complex scans until anti codon is found.

Q

What is The Process For Stage 2: Elongation

A
  1. 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.
