In science, the mantle is a layer of the earth between the core (inner layer) and the crust (outer layer).
The right answers are : b. nitrogenous bases c. phosphates d. sugars.
Deoxyribonucleic acid (DNA) is the genetic information of most living organisms (on the other hand, some viruses, retroviruses, use ribonucleic acid (RNA) as genetic information).
- DNA is a polymer, made of units called nucleotides (or mononucleotides).
- The nucleotide consists of a phosphate + a sugar + a nitrogenous base. In DNA, the nucleotide is a deoxyribonucleotide (in RNA, the nucleotide is a ribonucleotide).
Pretty sure they aren’t called flippers and if you Google that question you’ll get the answer ;)
