Entity: DNA
DNA is the genetic material found in all living cells and many viruses, consisting of two long strands of nucleotides twisted into a double helix structure. It determines the makeup of organisms and plays a crucial role in heredity.
DNA
Etymology
The term DNA stands for deoxyribonucleic acid.
Definition
DNA is the nucleic acid that serves as the genetic material determining the characteristics of all living cells and many viruses. It consists of two long strands of nucleotides linked together in a double helix structure.
Historical Context
DNA was first discovered in 1869 by Friedrich Miescher, but its role in genetics and heredity was not fully understood until the mid-20th century with the groundbreaking work of scientists such as James Watson and Francis Crick.
Cultural Significance
DNA has revolutionized fields such as forensic science, medicine, and biotechnology. It has provided insights into human evolution, ancestry, and genetic diseases.
Related Concepts
Other related concepts include genes, chromosomes, RNA, and genetic engineering.
