Question

why is DNA molecule considered as a negatively charged molecule​

Answer 1

Answer:

DNA has a negative charge due to the negative charge of its phosphate component. ... Phosphate links the sugars, called deoxyribose and from which DNA or deoxyribonucleic acid gets its name, to make up the backbone of each strand of DNA. Each sugar is linked to the next by a phosphate group.

Question => Why is DNA molecule considered as a negatively charged molecule ?

Answer => DNA (deoxyribonucleic acid) is the genetic information found in the nuclei of most organisms. It is arranged into structures called chromosomes. The structure of DNA was first identified as having a 'double-helix' structure by Watson and Crick in 1953. DNA is composed of 4 bases: the purines, adenine (A) and guanine (G) and pyrimidines ,thymine (T) and cytosine (C) . These form complementary base pairs of A-T and G-C. DNA also contains a phosphate group connected to a deoxyribose sugar. The phosphate group is attached to the sugar through a phosphodiester bond. Humans have 99.5% similarities with other humans in their DNA.
