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.

Wetlands form where water and land meet. a lake with a wetland fringe can fill in with decayed plant and animal material to become a wet meadow. a pond can fill in to become a bog or fen. sediment can fill in a river marsh to become a swamp.flooding of coastal lowlands from rising sea levels has created broad coastal marshes that are protected from wave action by barrier islands or reefs. coastal wetlands also form when rivers deposit sediment as they reach the ocean. plants then take root and hold the soil firm against the forces of tides and waves.
