Understanding DNA Transcription and Post-Transcriptional Modifications: Key Mechanisms and Clinical Implications
Summary: This presentation delves into the molecular mechanisms of DNA transcription, from RNA polymerase function to mRNA synthesis, followed by post-transcriptional modifications such as capping, splicing, and polyadenylation. It highlights the role of these processes in gene regulation, protein synthesis, and their impact on genetic disorders and therapeutic advancements.
