How dna genes and chromosomes are related

WebDNA is packaged into small units called chromosomes. A chromosome contains a single, long piece of DNA with many different genes. Every human cell contains 23 pairs of chromosomes. There are 22 pairs of numbered chromosomes, called autosomes, and one pair of sex chromosomes, which can be XX or XY. WebThese chains coil into 46 chromosomes, 23 from each parent. RNA ( r ibonucleic a cid) is similar to DNA; it also contains long chains of bases connected by a sugar ‘backbone’. Genes are the 1–2% of our genetic code that act as templates for making proteins. Proteins do most of the work in our cells so we can grow and stay healthy.

How are DNA, chromosomes, genes, and alleles related?

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).
