An organism's body is constructed using information in DNA or genetic material in the nucleus of cells.
DNA consists of sequences of nucleotide bases, which can be transcribed into mRNA, tRNA, and rRNA. The RNAs will then be transported to the cytosol of the cell and used in translation, where the codons on mRNA will be translated into specific sequences of polypeptide chains (aka.
