What is the function of transfer RNA (tRNA)?

• A. To synthesize proteins
• B. To transport specific amino acids to the ribosome
• C. To replicate DNA
• D. To activate transcription

Answer: (B)

Transfer RNA (tRNA) plays a crucial role in protein synthesis by transporting specific amino acids to the ribosome, where proteins are assembled. Each tRNA molecule is linked to a specific amino acid and has an anticodon that is complementary to the corresponding codon on the messenger RNA (mRNA). This ensures that the correct amino acid is brought to the growing polypeptide chain according to the instructions encoded in the mRNA sequence. When the ribosome is synthesizing a protein, tRNA molecules recognize the codons on the mRNA through their matched anticodons. This process ensures that amino acids are added in the correct sequence, which is vital for the proper structure and function of the resulting protein. In summary, the primary function of tRNA is to deliver the appropriate amino acids during translational processes in protein synthesis.
