c. 40 amino acids
d. 12 amino acids

Respuesta :

Answer:40

Explanation: a codon is three nucleotides. Provided that the sequence does not include a STOP codon, the polypeptide would have 40 amino acids

40 amino acids would be in the resulting polypeptide chain of a sequence of DNA that has 120 nucleotides.

CODONS:

  • A codon is a triplet nucleotide sequence in an mRNA molecule that encodes a particular amino acid. Each codon specifies an amino acid.

  • A codon is made up of three nucleotides, whose combination determines the amino acid that is encoded.

  • According to this question, a sequence of DNA has 120 nucleotides. This means that the number of codons that is accommodated in this sequence is 120/3 = 40 codons.

  • Since 1 codon specifies 1 amino acid, therefore, 40 codons will specify 40 amino acids.
