All body cells have a unique genetic code to create the proteins de body needs

The genetic code is store in the cell centre, where the chromosens can be found. These are made of a coat of proteins, with a dubble DNA-Helix in it.

The DNA exists of a double chain of nucleotiden. The order of the nucleotide is the basis of the genetic code.


transcription

To create a certain protein, starting from the genetic code you need

  • DNA
  • Messenger RNA
  • Transport RNA
  • Ribosomes in the cytoplasma


All starts in the cell core because the chromosones are locked in there. They can not migrate to the cytoplasma of the cell

In the centre, because of the working of the enzyme, the DNA opens up: the hydrogen-bridges between the bases are broken. the double helix is "zipped" open.

The piece of DNA that came off the bottom chain works as a possitive mold of which in the nucleus (core) a sort of neg ative copy is made in the shape of primary RNA


RNA is a Nucleic acid that is different from the DNA in a few facets

  • The chain is always single
  • The basis thymine is replaced by uracil
