Today I made a replica of some good old deoxyribonucleic acid.
Mmm. More commonly known as DNA, it is hidden in tiny, long structures called chromosomes. During cell division these chromosomes are duplicated in the process of DNA replication, providing each cell its own complete set of chromosomes. It grows something like this: One cell makes two, two makes four, four makes eight, etc.
