Detailed explanation-1: -Nucleotides that compose DNA are called deoxyribonucleotides.
Detailed explanation-2: -Nucleic acids, macromolecules made out of units called nucleotides, come in two naturally occurring varieties: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material found in living organisms, all the way from single-celled bacteria to multicellular mammals like you and me.
Detailed explanation-3: -Deoxyribonucleic acid (DNA) is a long, double-stranded, helical molecule composed of building blocks called deoxyribonucleotides.
Detailed explanation-4: -1. A molecule of DNA consists of two strands that form a double helix structure. DNA is a macromolecule consisting of two strands that twist around a common axis in a shape called a double helix.
Detailed explanation-5: -There are four different types of deoxyribonucleotides, they can also be called deoxyribonucleotide triphosphates (dNTPs): dATP (Deoxyadenosine Triophosphate), dCTP (Deoxycytidine Triophosphate), dGTP (Deoxyguanine Triophosphate), dTTP (Deoxythymine Triophosphate).
