Explanation Explanation/justification for the correct answer: Each tRNA molecule carries an anticodon, corresponding to the codons of the genetic code. The anticodons are nucleotide triplets that are complementary to the different codons. They allow the tRNAs carrying the appropriate amino acids to recognize the codons on the mRNA. This is essentially how the genetic code is ‘decoded’ to give the protein. Hence, option (b) is the right answer. Explanation for the incorrect answers: Option (a) is ‘contributes to the structure of ribosomes’...

Gene Interactions

When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of anoth…

Gene Expression

Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
