Respiration takes place in the mitochondria
I think the answer is C because at the first the DNA shows the copies of itself when it replicate n then it transcripts n transfer the coded message for protein synthesis from DNA onto mRNA n then it translates From the cytoplasm wher the RNA enters when it translate the part of protein synthesis from the time of amino acids are assembled in a particular sequence...The transcription happens from a nucleus
1. Diffusion
2. Osmosis
3. Facilitated Diffusion
DNA replication needs to occur because existing cells divide to produce new cells. Each cell needs a full instruction manual to operate properly. So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions!
