what alternate form of genes do nucleic acids have that allows them to offer variability?\n○ allele\n○ codon\n○ nucleotide\n○ chromosome
Answer
Brief Explanations:
To solve this, we analyze each option:
- Allele: Alternate forms of a gene (nucleic acids like DNA/RNA carry genes) that account for variation.
- Codon: A sequence of 3 nucleotides coding for an amino acid, not an alternate gene form.
- Nucleotide: The building block of nucleic acids, not an alternate gene form.
- Chromosome: A structure carrying genes, not an alternate gene form.
So the correct option is the one with "allele".
Answer:
A. allele
