What is DNA and why is it important?
DNA is a molecule found in most cells holding each person’s unique genetic code. It is responsible for coding proteins, which are essential to the growth and development of cells. Chromosomes are tightly coiled strands of DNA. Genes are sections of DNA that code individual proteins.
What would occur if we didn’t have DNA?
Without DNA, cells could not reproduce, which would mean extinction of the species. Normally, the nucleus makes copies of chromosomal DNA, then segments of DNA recombine, and next the chromosomes divide twice, forming four haploid egg or sperm cells.
Do all living things have DNA?
All living things have DNA within their cells. In fact, nearly every cell in a multicellular organism possesses the full set of DNA required for that organism. However, DNA does more than specify the structure and function of living things — it also serves as the primary unit of heredity in organisms of all types.
