The Central Dogma of Molecular Biology

Question

The Central Dogma of Molecular Biology describes the flow of information in a cell. Briefly name and describe the two key processes that the cell performs in order to transmit and utilize genetic information. A full answer should include naming the template and the end product of each process, and the location of each process inside a eukaryotic cell.

Answer 1

Central dogma includes transcription from DNA template to produce mRNA, it is transcribed from DNA and is a product of transcription and other molecular processes as well as a template for the next step of Central Dogma: Translation. Using mRNA as a template a number of factors initiate translation to synthesize protein or rather a polypeptide based on mRNA coding region. End product could be a single peptide or multiple peptides that form a protein using disulphide bonding of peptides. Transcription is initiated inside the nucleus but site of translation is in cytoplasm, primarily located on RER, containing tiny ribosomes that are also known as translation factories.
