Question

why DNA called deoxyribonucleic acid ?

Answer 1

because As you already know, the letters in DNA stand for "Deoxyribonucleic Acid." DNA is a polymer made up of monomers called nucleic acids, which are linked together in long chains. Each nucleic acid monomer is made up of a sugar (deoxyribose in DNA), a nitrogenous base, and a phosphate group.

Answer 2

Each nucleotide has three components a 5-carbon sugar, a phosphatae group and a nitrogenious base. If the sugar is dioxyribose, the polymer DNA. There are two types of nuclec acid - deoxyribonuclec acid better known as DNA. And ribonuclec acid better known as RNA.
