    Ribosomal RNA - carries aminoacids to the site of protein synthesis
  • B
    Transcription - process by which protein is synthesized
  • C
    Translation - process by which mRNA carries the information from nucleus to the ribosome
  • D
    Anticodon - site of tRNA molecule that contains complementary bases to the triple code on the mRNA
✓

Answer

  1. Anticodon - site of tRNA molecule that contains complementary bases to the triple code on the mRNA

Explanation:

One end of the tRNA matches the genetic code in a three-nucleotide sequence called the anticodon.

The anticodon forms three base pairs with a codon in mRNA during protein biosynthesis.

The mRNA encodes a protein as a series of contiguous codons, each of which is recognized by a particular tRNA.

On the other end of the tRNA is a covalent attachment to the amino acid that corresponds to the anticodon sequence.
