What are the 3 molecules that make up a nucleotide?

A nucleotide consists of three things:
  • A nitrogenous base, which can be either adenine, guanine, cytosine, or thymine (in the case of RNA, thymine is replaced by uracil).
  • A five-carbon sugar, called deoxyribose because it is lacking an oxygen group on one of its carbons.
  • One or more phosphate groups.

Similarly, it is asked, what are the 3 parts of a nucleotide?

Both deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are made up of nucleotides which consist of three parts:

  • Nitrogenous Base. Purines and pyrimidines are the two categories of nitrogenous bases.
  • Pentose Sugar. In DNA, the sugar is 2'-deoxyribose.
  • Phosphate Group. A single phosphate group is PO43-.

Additionally, what molecules make up nucleotides? Nucleotide RNA and DNA are polymers made of long chains of nucleotides. A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).

Moreover, what 3 molecules make up DNA?

DNA has three types of chemical component: phosphate, a sugar called deoxyribose, and four nitrogenous bases—adenine, guanine, cytosine, and thymine.

What are the three monomers that make up a nucleotide?

All nucleic acids are made up of the same building blocks (monomers). Chemists call the monomers "nucleotides." The five pieces are uracil, cytosine, thymine, adenine, and guanine. No matter what science class you are in, you will always hear about ATCG when looking at DNA. Uracil is only found in RNA.
