A codon is made up of

Aa two-nucleotide sequence.
Ba three-nucleotide sequence.
Ca four-nucleotide sequence.
Da five-nucleotide sequence.

Verified Answer :

A three nucleotide sequence. On mRNA, once it enters the ribosomes codons, ie AGU (adenine, guanine and uracil) is a codon, and is then paired with an anticodon of complementary bases which create a link of amino acids to create a protein.

The first path is from
the nucleus. DNA from the nucleus, assigns specific job for the organelles to
follow through mRNA. The mRNA goes out from the nucleus and enters the
cytoplasm where ribosomes will attach to the mRNA. The ribosome-mRNA
combination binds to the endoplasmic reticulum and signals the tRNA to translate
the message from DNA. The rRNA contains codons that will be used for the translation
of the messages by the tRNA. These codons has a three – nucleotide sequence. A
vesicle that contains the enzyme grows out from the endoplasmc reticulum ans
transport the enzyme to the Golgi body for further processing. The answer is
letter B.
