Question

Assertion : tRNA recognises its corresponding codon in mRNA.\ Reason : For each codon, there is an individual $t$ RNA.\

Professor PC Thomas Classes · Answer

(c): tRNA has an anticodon loop which has 7 bases, out of which three bases form anticodon for recognising and attaching to the codon of mRNA. Since there are 61 codons specifying amino acids, the cell should contain 61 different tRNA molecules, each with a different anticodon. Actually, however, the number of tRNA molecule types discovered is much less than 61 . This implies that the anticodons of some trNAs read more than one codon on mRNA.
