Double stranded DNA forms a helix structure and is found in this form in the nucleus of a eukaryotic cell. It is comprised of a sense and antisense strand that are complementary to each other and these bind to each other according to Watson-Crick base pairing rules. The nucleotide bases that make up DNA are guanine, cytosine, adenine and thymine. Guanine always forms hydrogen bonds with cytosine and adenine always forms hydrogen bonds with thymine. These bases are abbreviated to A,T,C and G. Double stranded DNA is split into single stranded DNA in the cell during processes such as DNA replication and transcription of DNA into mRNA. For a cell to fit all of its DNA into the nucleus, it must compress it down into chromosomes.
