In genetics, what is an allele?
A
The complete set of chromosomes in an organism (its genome)
B
A segment of RNA that serves as the site of ribosome binding during translation
C
A protein that increases the rate of a biochemical reaction without being consumed
D
An alternative version of a gene found at a specific locus on a chromosome
Verified step by step guidance1
Understand that an allele is related to genes and chromosomes, which are fundamental units of heredity in genetics.
Recall that a gene is a segment of DNA that codes for a specific trait or function.
Recognize that alleles are different versions or variants of the same gene that exist at the same position (locus) on homologous chromosomes.
Note that each individual inherits two alleles for each gene, one from each parent, which can be the same or different.
Conclude that an allele represents an alternative form of a gene that can influence the expression of a trait.
