The region of the chromosome or, more specifically, the length of the DNA molecule, which has a particular function is called _.
Correct answer: D. Gene
- A. Kinetochore
- B. Locus
- C. Allele
- D. Gene
Explanation
The gene is the basic physical and functional unit of heredity. It consists of a specific sequence of nucleotides at a given position on a given chromosome that codes for a specific protein. A kinetochore is a disc-shaped protein structure associated with duplicated chromatids in eukaryotic cells where the spindle fibers attach during cell division to pull sister chromatids apart. In genetics, a locus is a specific, fixed position on a chromosome where a particular gene or genetic marker is located. An allele is one of two, or more, forms of a given gene variant.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
