BIOL - From DNA to Protein
Biology, DNA, protein synthesis, transcription, translation - IGCSE | IBDP | DSE | GCE | IAL | AP Biology
Genes in our DNA provide instructions for building proteins.
For IGCSE Biology, you should be able to understand the steps of protein synthesis from DNA.

From DNA to mRNA (Transcription)
DNA is located inside the nucleus of cell. Since it is too large to be moved out of the nucleus into ribosomes, where protein is synthesized, a copy of a section of DNA is made to transfer the genetic information. The copy is called mRNA (messenger RNA), and the process is called transcription.
