of nucleotides , similar to DNA , but with a slightly different chemical structure. There are three main forms of RNA, each a slightly different function. mRNA (messenger RNA) is the mediating template between DNA and proteins. The information

of the structure of DNA in 1953 led to the central dogma of molecular biology: information flows from DNA to protein. Recent theories have explored selection at a variety of levels including gene, organism, kin, group, and species, as
