DNA is twisted. Why?
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.
