Question

Using this sequence: 5’ AUG GAG AGC CUU GUC CCU 3’ find:

a) The translation product, indicating the N terminus and the C terminus, and using the one-letter code for amino acids

b) The complementary non-coding RNA sequence that will serve as a template to the synthesis of other viral genomes, indicating the 5’ and 3’ ends

Answer 1

The given mRNA sequence: 5’ AUG GAG AGC CUU GUC CCU 3’

a) The translation is a process in which polypeptide is synthesized with mRNA as a template. The set of three bases of the mRNA acts as a codon, each codon codes for an amino acid in the translation process.

So, the amino acid sequence of the polypeptide will be: MET GLU SER LEU VAL PRO

Or in one letter code along with N and C terminus: N - MESLVP - C

b) The complementary non-coding RNA will be complementary to the given RNA sequence. Complementary means that A ic complement to T, G is a complement to C and vice-versa.

So, the complementary RNA will be: 3' UAC CUC UCG GAA CAG GGA 5'
