Solution
The correct option is C Gene
Eukaryotic DNA has introns and exons. The protein coding part of eukaryotic DNA is exon while the gene sequences that are present between exons and do not code for any protein product are called as introns. Genes are the stretch of DNA that specify a particular protein and thereby control a specific trait in the organism; they are the unit of heredity. A mutation in a gene is manifested in its governed protein’s structure and function which in turn now express the mutant trait. A cistron is defined as the unit of function that exhibits cis-trans test; it is not the unit of inheritance. A gene carries several cistrons. Chromosomes are the threadlike structures, present in the nucleus, and are made up of DNA and proteins. Genes are present in the linear fashion on chromosomes which in turn serve to carry them from one generation to next. The correct answer is D.
