What are the 3 parts of a DNA 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-.

Furthermore, what are the three parts of a DNA nucleotide quizlet?

This is known as double helix. Nucleotides each have three parts: phosphate, sugar molecule, and one of four bases. The bases include: A, (adenine), g (guanine), t (thymine), c (cytosine).

Likewise, what are the 3 types of DNA? Three major forms of DNA are double stranded and connected by interactions between complementary base pairs. These are terms A-form, B-form,and Z-form DNA.

Also to know is, what are the three parts of a DNA nucleotide and how are they connected to each other?

The three parts are a deoxyribose sugar, a phos- phate group, and a nitrogenous base. The phosphate group and the base are connected to different parts of the sugar.

What is DNA made of?

DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.
