Question

A solution of purified DNA will have pH

A. Basic

B. Highly basic

C. Acidic

D. Neutral

Answer 1

Deoxyribonucleic acid comprises deoxy sugar, Nitrogenous base and Phosphoric acid. Nitrogenous bases in DNA are Thymine, Cytosine, Adenine and Guanine almost every cell of the human body has the same DNA. It is only in the case of alike twins that they have completely the same DNA. Otherwise no one can have completely the same DNA.

Complete answer:

DNA, or deoxyribonucleic acid, is the genetic material in people and practically all different life forms. Virtually every cell in an individual's body has a similar DNA. Most DNA is situated in the cell nucleus.The data in DNA is put away as a code comprising four nitr bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA comprises around 3 billion bases, and in excess of 99 percent of those bases are the equivalent in all individuals. The arrangement of these bases decides the data accessible for building and keeping up a living being, like the manner by which letters are arranged and show up in a specific order to shape words and sentences.

DNA bases pair up with one another, A with T and C with G, to frame units called base pairs. Each base is additionally joined to a sugar and a phosphate molecule. Together, a base, sugar, and phosphate are known as a nucleotide. Nucleotides are ordered in two long strands that structure a twisting called a double helix. The structure of the double helix is to some degree like a stepping stool, with the base pairs shaping the stepping stool's rungs and the sugar and phosphate atoms framing the vertical side pieces of the stepping stool.

A significant property of DNA is that it can replicate, or make duplicates of itself. Each strand of DNA in the double helix can fill in as an example for copying the sequence of bases. This is important when cells divide in light of the fact that each new cell needs to have a precise of the DNA present in the old cell.

So, the correct answer is option C.

Note: In the event that you analyze the structures of phosphoric acid and a short strand of DNA, we'll see that in the last mentioned, two protons of phosphoric corrosive are replaced via carbon either in, or joined to, the five-membered ring. In chemical terms, such a gathering is known as a phosphate diester. The rest of the proton is currently very acidic, and is moderately effortlessly lost, in this manner giving DNA its acidic character. In reality, under neutral conditions, DNA is deprotonated at this site, and the oxygen bears a negative charge. In spite of the way that DNA contains numerous fundamental gatherings, their essential properties are veiled to some degree as a result of the way that they hydrogen bond with one another to shape base pairs. Thus it's the acidic aspect of the particle that rules, and that is the reason we know DNA as acidic.
