DNA, which stands for deoxyribonucleic acid, is a molecule that supplies the hereditary instructions that tell living creatures how to develop, live and reproduce. DNA can be found inside every cell and is passed down from parents to their offspring.
What’s DNA produced from?
DNA is made up of molecules called nucleotides. Each nucleotide contains three components: a phosphate group, which is one phosphorus atom bonded to four oxygen atoms; a sugar molecule; and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C), and together, these serve as the „letters” that make up the genetic code of our DNA.
Nucleotides is affixed with her to form one or two long strands that spiral to make a routine called a two fold helix. If you were to think of twice-helix framework site here just like the a ladder, the fresh phosphate and you can glucose molecules will be edges, because ft sets is the rungs. The new basics on a single strand pair into the angles toward some other strand: Adenine sets which have thymine (A-T), and you may guanine pairs having cytosine (G-C).
Human DNA is made up of around 3 billion base pairs, and more than 99% of those bases are the same in all people, according to the You.S. read more
