During protein synthesis, an anticodon on transfer RNA (tRNA) pairs with ______.

विकल्प

• messenger RNA (mRNA) nucleotide bases

• ribosomal RNA (rRNA) nucleotide bases

• other tRNA nucleotide bases

• DNA nucleotide bases

Answer 1

During protein synthesis, an anticodon on transfer RNA (tRNA) pairs with messenger RNA (mRNA) nucleotide bases.

Explanation:

During the translation phase of protein synthesis, the tRNA molecule acts as an adapter that bridges the gap between the genetic code and the growing protein chain. Each tRNA carries a specific amino acid and possesses a unique triplet of bases known as an anticodon. This anticodon recognises and binds to a complementary three-base sequence on the mRNA called a codon through hydrogen bonding. This precise base-pairing ensures that amino acids are added in the exact order specified by the genetic instructions originally transcribed from DNA.
