... RNA [mRNA] as it contains the protein information. This mRNA leaves the nucleus through a nuclear pore, DNA is too large a molecule to do this, to the cytoplasm. In the cytoplasm there are free transfer RNA [tRNA] molecules which hve three protruding bases these sets of three on the tRNA are called anti-codons. Each tRNA molecule attracts different amino acids, of which there are around twenty, and they "stick" to the tRNA and depending on which tRNA molecule it is it wil attract a diferent amino-acid.On the RNA every three bases are called codons these are complementary to the anti-codons of the tRNA. For instance a codon of - GAA - would p ...
