The scientific study of life is known as biology. Although it is a natural science with a large reach, it is tied together as a single, cohesive field by a number of commonalities. For instance, every organism consists of cells that process genetic information that can be passed on to future generations. The explanation for the unity and diversity of life is provided through evolution, which is a major theme. Processing energy is essential to life since it enables movement, growth, and reproduction in living things. And last, all living things have the capacity to control their own interior surroundings.
DNA is well-known for its well-known twisted form. This shape is frequently referred to as a twisted ladder or spiral staircase. DNA is a nucleic acid that is made up of three main parts: phosphate molecules, deoxyribose sugars, and nitrogenous bases. This nucleic acid takes on a twisted shape due to interactions between water and the DNA molecules. DNA is more easily packed into chromatin fibers, which condense to form chromosomes, thanks to this shape. DNA replication and protein synthesis are also made possible by its helical shape. The double helix opens and unwinds when necessary to permit DNA replication.
