Select your answer for: DNA stands as an abbreviation for ____________________?
Show answer

Answer: A. molecular configuration making up chromosomes

Explanation

DNA stands for deoxyribonucleic acid forming the double helix molecular configuration within chromosomes. Nucleotide base pairs arrange along the DNA backbone to encode hereditary biological instructions. Chromosomes consist of tightly coiled DNA strands carrying genetic information across cell divisions. James Watson and Francis Crick discovered the molecular structure of DNA in nineteen fifty three. Adenine pairs with thymine while cytosine pairs with guanine in the DNA double helix. Genetics studies how DNA molecules dictate protein synthesis and cellular functional characteristics.

Forensic scientists use DNA profiling to identify suspects in criminal justice investigations. Medical geneticists analyze DNA sequences to diagnose inherited diseases and chromosomal disorders. Biotechnology researchers manipulate DNA to develop agricultural improvements and therapeutic pharmaceuticals. Germ cell configurations represent cellular reproductive structures rather than the molecular DNA makeup. Atom structure in genes refers to subatomic chemistry rather than the macromolecular DNA configuration. Neural structure describes brain cell anatomy rather than the genetic composition of chromosomes.
