The four nitrogen bases in a DNA molecule are thymine, adenine, cytosine, and guanine.
A chromosome is the basic unit of which the DNA molecule is found and a chromosome is where every genetic trait is found in human beings.
The discovery of DNA is important because it is the basic unit of genetics...(I think)
And the DNA molecule is a double helix form in which has nitrogen bases with a backbone made up of a 5-carbon sugar called deoxyribose and phosphate.

the four bases of DNA is adenine, thymine, guanine, and citosine. A chromosome is made up of DNA wound up in proteins called histones. DNA, consists of four nucleotides- which is a dexoyribose molecule, a phosphate molecule, and one of the four nitrogenous bases. Every adenine is always connected to a thymine, and a guanine is always connected to a citosine by a weak hydrogen bond. there can be millions of neuclotides in a single strand of DNA As for the structure, two scientists (watson and Crick) found out that DNA is a double helix

4 bases are: Adenine and Thymine, and Glycine and Cytosine.
Chromosome: structure that contains a single molecule of DNA
DNA is a double helix and it's made up of 4 nucleotides (the bases i mentioned before) and the outside part of a DNA molecule are sugar molecules and phosphates..
Hope that helps! good luck

the person above me is right, DNA is basicly a type of sugar, and our cells are also a type of sugar, it is interesting the we use other types of sugar as fuel.
