a)
Interpretation:
List anticodon sequence on the tRNAs of the given amino acids.
AAU
Concept introduction:
The main function of messenger RNA (mRNA) is to give the direction to biosynthesis of thousands of diverse peptides and proteins required by organisms. The mechanics of protein biosynthesis take place on ribosomes, small granular particles in the cytoplasm of a cell that consist of 60% ribosomal RNA and 40% protein.
The specific sequence of mRNA forms a message which determines the sequences of amino acid residues which are to be joined known as “codon”. Each “word” or codon consist of three ribonucleotides that is specific for a given amino acid. The message embedded in mRNA is read by transfer RNA (tRNA) in a process called translation.
Codon assignments of base triplets are given below:
Note: The bounded amino acid sequence is always written from 5’→3’ direction. The codon sequences on mRNA are read by tRNA which are having complementary anticodon base.
Answer to Problem 28AP
The anticodon sequence on the tRNAs of the amino acids are given below:
Note: As in the previous question (80485-28-27AP), the codon sequences formed are the mRNAs and hence the complement of mRNAs will give rise tRNAs.
AAU
| Codon Sequence (mRNA) | Anticodon Sequence (tRNA) |
| (5’)-AAU-(3’) | (5’)-AUU-(3’) |
Explanation of Solution
As the anticodon sequence on tRNAs are the complement of the mRNAs, therefore, we will just replace A by U, G by C, U by A and C by G. The number of sequence of anticodon will remain same as that of the codons.
