Semi-conservative
During cell division the DNA molecule has to be copied, one method of doing this is called semi conservative replication. This is done by the molecule first unwinding due to the DNA helicase enzyme. The hydrogen bonds then break between the bases the two strands then separates. The strands then work as templates to bring free nucleotides to form a complementary strand with the complementary bases. The DNA polymerase enzyme then combines the nucleotides and the end result are two identical DNA molecules
Protein Synthesis
DNA is a collection of genes used to make proteins for the body, these protein are made of amino acids. Three bases (a triplet code) makes a amino acid.
Transcription) The DNA double helix unwinds, MRNA then attaches and forms the complementary bases, the MRNA is able to move in and out of the nucleus as it is only one strand.
Translation) The MRNA leaves the nucleus and attaches to a ribosome and is read by TRNA, it reads the triplet codes and brings the correct amino acids in the right order to make protein
