Describe the process of protein synthesis. (Essay)
There are two parts of protein synthesis, transcription (making of mRNA) and translation (making of a protein). Thranscription has RNA polymerase come into the nucleus, find the specific gene that we are looking for and make a copy of it and create mRNA. In translation, the mRNA leaves the nucleus and moves to the active portion of the ribosome. The ribosome must read the start codon (AUG) in order to start protein synthesis. tRNA then has to come down and is the anticodon or pair for that codon (tRNA comes from the food we eat, so if we are not eating all of our amino acids, we won't have tRNA). After tRNA pairs with the codon it becomes a true amino acid where it moves to the passive site. The next codon comes in and does the same thing, along with the next. Protein synthesis stops when the active site of the ribosome reads the stop codon, which does not have an anticodon, or tRNA pair. The true amino acids then leave the ribosome from the passive site and goes to whatever part of the body needs that protein.
