Question

.Given mRNA sequences, provide the amino acid sequences, using the three-letter designations, for which they code. A link to a table of codons can be found here. a) mRNA: 5\'–AUUCCCAUAUCU–3\' amino acid sequence: b) mRNA: 5\'–CCGAAUGCGCCC–3\' amino acid sequence: c) mRNA: 5\'–CAACGUAAUCGA–3\' amino acid sequence:

Answer 1

It is known that three nucleotide bases on mRNA are called codon and that each codon codes for the specific amino acid. According to the genetic code chart, the following mRNA sequences will code for the following amino acid sequences:

a) mRNA: 5\'–AUU CCC AUA UCU–3\'
amino acid sequence: Ile-Pro-Ile-Ser

b) mRNA: 5\'–CCG AAU GCG CCC–3\'
amino acid sequence: Pro-Asn-Ala-Pro

c) mRNA: 5\'–CAA CGU AAU CGA–3\'
amino acid sequence: Gln-Arg-Asn-Arg
