Unveiling the Secrets of DNA

DNA, or deoxyribonucleic acid, is a molecule that contains the genetic instructions for the development and functioning of all living organisms. It carries the genetic information that determines an organism's traits and characteristics.

DNA is composed of nucleotides, which consist of a sugar molecule (deoxyribose), a phosphate group, and a nitrogenous base (adenine, thymine, cytosine, or guanine).

DNA replication is a process where a DNA molecule makes an identical copy of itself. It involves the separation of the two DNA strands, followed by the synthesis of complementary strands using the existing strands as templates.
