The central dogma of molecular biology describes the flow of genetic information from DNA to RNA to protein through the processes of replication, transcription, and translation. DNA is replicated in the nucleus, transcribed to mRNA, and then translated by ribosomes into proteins. This document outlines the roles of DNA, RNA, and proteins in cellular functions.
Central dogma of molecular biology
- 1. The Central Dogma of Molecular Biology By Engr. Ijaz-Ul-Haq
- 2. The Flow of Information A gene is expressed in two ways DNA is transcribed into RNA Then RNA is translated into protein
- 3. Theme of Central Dogma Replication Transcription Translation DNA RNA Protein
- 4. DNA Polymerase Replication DNA to DNA RNA Polymerase Transcription DNA to RNA Ribosome Translation RNA to Protein DNA RNA Protein
- 5. Transcription Translation DNA RNA Protein Replication Reverse Transcription
- 6. Description DNA Stored information inside nucleus Copied to make new cell = REPLICATION RNA Copied from a piece of DNA (GENE) to make a single protein = TRANSCRIPTION Moves information from nucleus to cytoplasm Protein Information from a single RNA used to make a single protein = TRANSLATION
