WebDNA, genes and chromosomes work together to make you who you are. Chromosomes carry DNA in cells. DNA is responsible for building and maintaining your human structure. ... wrap up DNA like a spool to make it small enough to fit into your cells. If chromosomes didn’t wrap around DNA, your DNA would be 6 feet long from end to end. Conditions ... WebDNA is a long polymer made from repeating units called nucleotides. The structure of DNA is dynamic along its length, being capable of coiling into tight loops and other shapes. In all species it is composed of two helical chains, bound to each other by hydrogen bonds.Both chains are coiled around the same axis, and have the same pitch of 34 ångströms (3.4 nm).

WebDNA supercoiling refers to the process by which DNA is twisted to fit inside the cell. Supercoiling may result in DNA that is either underwound (less than one turn of the helix per 10 base pairs) or overwound (more than one turn per … WebThe length of a chromosome greatly exceeds the length of the cell, so a chromosome needs to be packaged into a very small space to fit within the cell. For example, the combined length of all of the 3 billion base pairs [1] of DNA of the human genome would measure approximately 2 meters if completely stretched out, and some eukaryotic genomes ... cite industry report
