Compare and contrast the processes of rna transcription and rna translation

RNA transcription occurs in the nucleus. This is the process of turning DNA into mRNA. To do so, it would be using a RNA Polymerase. This enzyme codes the RNA strand using the DNA strand as a template. But before the RNA Pol. can transcribe it, it isn’t able to just bind onto the DNA by itself. First, helicase will come in and unwind the DNA. There will be a promoter region where the TATA Box lies. Transcription factors will bind there and this lets the RNA Polymerase know where to bind. Once RNA Polymerase sees the Transcription Factors and binds to the promoter, it will start to code for the RNA. RNA Translation is turning mRNA into a polypeptide (protein). It occurs in the cytoplasm. We will need tRNA, mRNA, Ribosome, and amino acids for this step. The mRNA will bind to the ribosome. tRNA is in charge of bringing the correct amino acids that match with each codon of the mRNA sequence. As it brings the amino acid, a peptide chain will form. Once it gets to the end, the peptide chain will fall off and form a polypeptide.
