Kitty [74]

Answer:

For the tRNA anticodon CCA the corresponding codon is GGU, which codes for the amino acid Glycine (Gly).

Explanation:

Transfer RNA or tRNA is responsible for driving the right amino acid into protein synthesis, once the mRNA codon has been translated by the ribosome. It is for that reason that each mRNA codon must have a complementary tRNA anticodon.

The RNA pairing rules is that each nitrogenous base has a complementary base, so:  

- Adenine is complementary with uracil A=U

- Cytosine is complementary with Guanine C=G

In this case, it can be seen that:

  • <em>For the anti-codon:  CCA</em>
  • <em>Codon:                      GGU</em>
  • <em>Aminoacid:               Gly</em>
