5) Central dogma of life
Ms. Ojaswini Bhagat and Ms. Vaishnavi Ingle, M.Sc First Year Microbiology students, along with Ms. Bhumika Mirashi from the B.Sc Final Year, have delved into the central dogma of molecular biology, a fundamental framework illustrating the flow of genetic information within cells. This concept encompasses DNA replication, transcription, and translation: DNA is replicated to generate more DNA, transcribed into mRNA, and then translated into proteins. This sequence is crucial for understanding how genetic information is transferred and expressed within organisms. Biopolymers, including proteins, RNA, and DNA, play essential roles in this process. Standard biological information flow includes DNA replication (DNA copied to DNA), transcription (DNA information transcribed to mRNA), and translation (mRNA used as a template for protein synthesis). Special processes involve RNA replication (RNA copied from RNA) and reverse transcription (DNA synthesized from an RNA template). Some unknown processes, such as direct protein synthesis from DNA without mRNA or the use of protein structures as templates for RNA or DNA synthesis, remain subjects of active research.
In their experiments, Ms. Bhagat, Ms. Ingle, and Ms. Mirashi are exploring these fundamental mechanisms to deepen their understanding of genetic information manipulation and expression. Their research aims to push the boundaries of the central dogma, potentially uncovering novel mechanisms and advancing applications in genetic research and biotechnology.
