(i) What is charging of tRNA?

(ii) Write the codon on mRNA and anticodon on tRNA for methionine amino acid?

(iii) Write the structure of tRNA molecule. Name the codons which do not have any tRNA.

Answer:

(i) Charging is the process through which the activated amino acids (activation in the presence of ATP) get linked to their cognate tRNA.

(ii) For methionine, codon on mRNA is AUG and anticodon on tRNA is UAC.

(iii) The actual structure of tRNA is inverted L - shape. There are no tRNAs for stop codon.
