What is the term for the location of a gene on a chromosome?

• A. Codon
• B. Allele
• C. Locus
• D. Chromosome

Answer: (C)

The correct term for the location of a gene on a chromosome is "locus." In genetics, a locus is a specific fixed position on a chromosome where a particular gene or genetic marker is located. Each gene has a specific locus, which helps in identifying its position in the genome. Understanding the concept of a locus is important because it allows scientists and researchers to map genes, understand genetic variation, and study inheritance patterns. A gene’s locus provides essential information for genetic studies, such as identifying mutations or variations that might affect traits or diseases. The other terms have different meanings in genetics. A codon is a sequence of three nucleotides that together form a unit of genetic code in a DNA or RNA molecule. An allele refers to one of the different forms of a gene that can exist at a given locus. A chromosome is a long DNA molecule with part or all of the genetic material of an organism; it contains many loci, each corresponding to different genes. Understanding these distinctions is crucial for grasping the concepts of genetics and genomics.
