Transcription Of DNA to mRNA

HideShow resource information

Protein Synthesis

DNA is a double helix anti-parallel structure contained in the nucleus of every cell in our body. It is the code to making every cell in your body, and so if it is copied incorrectly a mutation will occur.

But the 'code' needs to be taken to the ribosomes (the protein factory) to make enzymes and proteins. But because DNA is too big to leave the nucleus through the nuclear pores only the section required to make the protein is copied as an mRNA.

mRNA is a single strand and is much shorter than DNA (its a snip of DNA) so it can pass through the nuclear pores to the




Great notes XD Thank you :')

thank you anytime



umm to says RNA polymerase unwinds the double helix....isnt it DNA helices that does this?
