Question

what alternate form of genes do nucleic acids have that allows them to offer variability?
○ allele
○ codon
○ nucleotide
○ chromosome

Explanation:

To solve this, we analyze each option:

• Allele: Alternate forms of a gene, contributing to genetic variability.
• Codon: A sequence of three nucleotides that codes for an amino acid, not an alternate gene form.
• Nucleotide: The building block of nucleic acids (like DNA/RNA), not a gene variant.
• Chromosome: A structure carrying genes, not an alternate gene form.

So the correct option is the one that represents alternate gene forms.

Answer:

A. allele
