what is the importance of dna molecules living organisms
Answers
Answer:
DNA. Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things. All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information.
Explanation:
DNA is a complex, long-chained molecule that encodes the genetic characteristics of a living organism. In most plants and animals, DNA is packaged with ribonucleic acid and proteins into compact structures called chromosomes that reside in the cell nucleus. Almost all human cells have 23 pairs of chromosomes, one set from each parent. DNA sections called genes indirectly code for proteins, which give structure and function to human bodies. The choice of which genes operate in which cells determines the cell’s type: brain, liver, skin and all others.
