Molecular Biology is a branch of biology that focuses on the molecular basis of biological activity, especially the interactions between DNA, RNA, proteins, and how these molecules regulate cellular processes. Molecular Biology studies the structure, function, and regulation of genes and the molecules involved in genetic information flow, including DNA replication, transcription, translation, and gene regulation.
Molecular Detection of Microorganisms Introduction The deoxyribonucleic acid (DNA), ribonucleic acid (RNA), or proteins of an infectious agent in a clinical sample can be used to help identify the agent. …
RNA Interference or RNAi Introduction RNA interference (RNAi) or Post-transcriptional gene silencing (PTGS) is a process of gene silencing or sequence-specific mRNA degradation. It is a phenomenon inside a cell …
Tryptophan Operon: History, Structure, Regulation and Attenuation Introduction The discovery and explanation of the Operon model can be regarded as the milestone in the field of molecular biology. In 1961 …
Pathogenicity Islands (PAI) The DNA of bacteria is dynamic, other than the core genome; it’s composed of mobile elements, for instance, transposons, a genetic island that can be transferred through …
DNA Replication in eukaryotes Content Introduction DNA Replication in Eukaryotes Initiation of DNA Replication in Eukaryotes Eukaryotic Primases and DNA Polymerases Telomeres and Telomerases Introduction DNA replication is similar in …
Proteomics: Introduction, Methods,Types and Application Introduction Genome function can be studied at the translation level as well as the transcription level. The entire collection of proteins that an organism produces …
Transcription: Initiation, Elongation and Termination Introduction of Transcription The synthesis of RNA under the direction of DNA is called transcription. The RNA product has a sequence complementary to the DNA …
