Gene Expression (c)

Question 1

Explain translation and the role tRNA has with it.

Answer 1

• tRNA is involved in the translation of
  mRNA into a polypeptide at a ribosome.
  -Translation begins at a start codon and
  ends at a stop codon.
• Anticodons bond to codons by complementary base pairing, translating the genetic code into a
  sequence of amino acids.
• Peptide bonds join the amino acids together.
• Each tRNA then leaves the ribosome as the polypeptide is formed.
