Which of the following statements is true about codons?

Question

Codons are made up of groups of two bases.

To reduce the chances that a mistake in translating the code will result in synthesizing an unusable protein, more than one codon codes for the same amino acid.

Codons allow the deoxyribonucleic acid (DNA) to be copied to a ribonucleic acid (RNA) strand.

Codons are groups of four bases.

Answer 1

The true statement about codons is:

To reduce the chances that a mistake in translating the code will result in synthesizing an unusable protein, more than one codon codes for the same amino acid.

Here's a brief explanation of the other statements:

1. Codons are made up of groups of two bases. - This statement is false. Codons are made up of groups of three bases (nucleotides).

2. Codons allow the deoxyribonucleic acid (DNA) to be copied to a ribonucleic acid (RNA) strand. - This statement is misleading. While codons are part of the RNA sequence, it is the process of transcription that allows DNA to be copied into RNA, not the codons themselves.

3. Codons are groups of four bases. - This statement is false. Codons consist of groups of three bases (nucleotides).

Thus, the second statement about redundancy in the genetic code is the only correct one.
