<em>A. a segment of DNA</em>
Further explanation
Genes are inheritance units of living organisms. Its physical form is that the sequence of DNA attached to a protein, polypeptide, or strand of RNA that incorporates a function for the organism that owns it. the trendy boundary of genes may be a specific location within the genome that's associated with inheritance and may be linked to functions as a regulator, target transcription, or other functional roles. the utilization of genes in everyday conversation is commonly intended for alleles: the selection of variations available by a gene. Although allele expressions will be similar, people more often use the term allele for organic phenomenon that's phenotypically different.
DNA may be a supermolecule that stores all the unique biological information of each physical object and a few viruses. Its chemical structure is within the sort of complex macromolecules consisting of three sorts of molecules, namely pentose sugar (deoxyribose), orthophosphoric acid, and nitrogen bases. the most role of DNA molecules is that the long-term storage of knowledge.
DNA segments that carry genetic information are called genes, but other DNA sequences that have structural purposes, or are involved in regulating the utilization of genetic information.
DNA can replicate ie form copies of itself. Each DNA strand contains a particular base sequence. Each base is additionally connected by sugar and phosphate molecules. If the bottom forms a rung (horizontal), then the sugar and phosphate molecules form the vertical a part of the ladder.
