Question

What alternate form of genes do nucleic acids have that allows them to offer variability?A) alleleB) codonC) nucleotideD) chromosome

Answer 1

Most organisms have two copies of each gene, one from their mother and another from their father. These copies can be the same or different because there are different versions of each gene. Each version is called an allele, and it gives a different characteristic to the organism, making them variable.

This means A) allele, is the right answer.
