Study Notes
mRNA and the Central Dogma of Molecular Biology
- mRNA (messenger RNA) acts as the intermediary between DNA and proteins, carrying genetic information from DNA to the ribosomes.
- It is crucial for the transcription and translation processes, enabling the synthesis of proteins essential for cellular functions.
Study of Microbial Genetics
- Microbial genetics is focused on understanding the heredity in microorganisms such as bacteria, viruses, fungi, and archaea.
- This field explores how genetic information is transmitted, expressed, and regulated in microbes, influencing their traits and behaviors.
Techniques in Microbial Genetics
- The study involves techniques like genetic mapping, isolation of mutant strains, and sequencing of microbial genomes.
- It also examines gene expression, regulation, and the roles of plasmids and transposons in microbial adaptability and evolution.
Central Dogma of Molecular Biology
- The Central Dogma outlines the flow of genetic information within a biological system: DNA → RNA → Protein.
- This framework explains how genetic material is replicated, transcribed, and translated into functional proteins, which carry out cellular activities.
