    • In Humans the Nucleus contains 46 chromosomes (23 Pairs).
    • A DNA Molecule is in the shape of a Double Helix
    • DNA is made up of 4 bases each with a complimentary pairing to each other. Adenine links with Thymine and Cytosine links to Guanine.
    • The two strands are held together by hydrogen bonds between complementary base pairs.
    • Genes are the basic units of heredity and are located on chromosomes.
    • mRNA exists as a single stranded molecule until it is translated into a Polypeptide because it is complementary to the sequence of amino acids on the Ribosome. This is because DNA is to large leave the Nucleus and fit into the Ribosome.
    • Protein Synthesis occurs at ribosomes which are found in the cytoplasm.
