What is DNA and who discover DNA?
Answers
Deoxyribonucleic acid, more commonly known as DNA, is a complex molecule that contains all of the information necessary to build and maintain an organism. All living things have DNA within their cells. In fact, nearly every cell in a multicellular organism possesses the full set of DNA required for that organism.
In simple
Dna is Deoxyribonucleic acid it is the nucleus matter and present inside nucleus of a cell it is a genetic thing
DNA was first identified in the late 1860s by Swiss chemist Friedrich Miescher
DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person's body has the same DNA. ... The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T).
Function:-
The major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code. To read the genetic code, cells make a copy of a stretch of DNA in thenucleic acid RNA.
Hydrogen bonding:-
The nucleotides forming each DNA strand are connected by noncovalent bonds, called hydrogen bonds. Considered individually, hydrogen bondsare much weaker than a single covalent bond, such as a phosphodiester bond. But, there are so many of them that the two DNA polymers are verystrongly connected to each other.
