Come è composto il DNA?
Come abbiamo detto, il DNA, così come l'RNA, è un acido nucleico costituito da subunità chiamate nucleotidi. ... La molecola del DNA è formata da due catene polinucleotidiche appaiate e avvolte intorno allo stesso asse, in modo da formare una doppia elica.
What is DNA in simple terms?
- DNA EXPLAINED IN EASY TERMS. DNA is material that governs inheritance of eye color, hair color, stature, bone density and many other human and animal traits. DNA is a long, but narrow string-like object. A one foot long string or strand of DNA is normally packed into a space roughly equal to a cube 1/millionth of an inch on a side.
What is DNA an example of?
- DNA 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.
What is DNA used for?
- It's used as evidence in courts, to identify bodies, track down blood relatives, and to look for cures for disease. DNA is short for deoxyribonucleic acid, which is inside of every cell in your body. It's a chain of chemical compounds that join together to form permanent blueprints for life.
What are the results of DNA?
- The result of DNA replication is two DNA molecules consisting of one new and one old chain of nucleotides. This is why DNA replication is described as semi-conservative, half of the chain is part of the original DNA molecule, half is brand new.
