In my microbiology class, we are learning in depth about replication, transcription and translation. Each time a cell replicates, the double strands of DNA splits in 2. Each of these single strands are soon going to become a double strand as they were getting their DNA copied. In transcription, DNA is transcribed to mRNA. This carries the necessary information for protein synthesis. mRNA trasncription occurs in the cytoplasm. Addditionally, transcription is the first step in gene expression. Then, tRNA occurs in the nucleus, and rRNA occurs in the nucleoulous. The translation machinery occurs in the ribosomes, which acts like a taxi in the eukaryotic cell. At the end of translation, we have a polypeptide.
