Question

Which of the following statements is true of the genetic code?

a. three-letter codons each specify one amino acid.
b. three-letter polypeptides each specify one nucleotide.
c. five-letter dna sequences each specify one rna molecule.
d. five-letter anticodons each specify one amino acid.

Answer 1

Answer: a. three-letter codons each specify one amino acid.

Step-by-step explanation:

• The genetic code is a set of rules which dictates how the information present in DNA and RNA is translated to form amino acids.

• According to the genetic code, the DNA has a codon made up of three nucleotides and, each codon is responsible for coding an amino acid.

• For example, the codon UUU codes for the amino acid phenylalanine.

Answer 2

When we say genetic codes, this includes a three-letter nucleotide that carries both the DNA and RNA molecules that are responsible for our genetic information. Therefore, based on the statements above, the one that is true about genetic code is option A. Hope this helps.
