Question

If a tRNA molecule contains the amino acid Proline on one end of the molecule, a possible anticodon in this tRNA would be ________. The codon that this anticodon would bind to in the mRNA sequence would be: ________.

Answer 1

Let's understand First Codon and Anticodon

A codon is a three nucleotide sequence code for a particular amino acid. This sequence is triplet present on mRNA. The complementary sequence to codon is called anticodon present on tRNA.

There are different 64 triplet or genetic code present and code for about 20 amino acid. Based on base pairing rule, C pairs with G while A pairs with U or T(in DNA)

The proline amino acid has mRNA sequence or code or codon are CCU, CCC, CCA, CCG. All these 4 codons are for proline amino acid, so there are 4 possible anticodons are which are complementary to these codons are

GGA, GGG, GGU, GGC.
