What is the relationship between DNA, genes, chromosomes, etc?
In: Biology
*DNA* — a chemical substance that life uses to store genetic information. It is a polymer — long chain consisting of a lot of connected parts.
*nucleotide* — a single part of that chain.
*base* — the part of the nucleotide that differs between nucleotides (that’s why from the information point of view the words nucleotide and base are sometimes used interchangingly).
*gene* — a fragment of DNA that encodes a single protein
*chromosome* — a DNA molecule in eucaryotic (not bacteria) cell with some proteins that “manage” it. They contain multiple genes.
