Nucleotide is the basic structural unit (monomer) of a nucleic acid such as DNA.

DNA is a polymer of nucleotides that contains genetic information of a cell. A DNA nucleotide is made up of three parts which are; a nitrogen base, a five-carbon sugar, and a phosphate group.

An allele is a possible form of a gene. Genes usually have two alleles; a recessive allele and a dominant allele.

A gene is a small part of DNA that stores information.

Chromosomes are thread-like structures, composed of protein and one molecule of DNA that carry genetic information in the form of genes.
