Surgical Site Infection (SSI) is a type of infection resulting from a surgical procedure. Center for Disease Control (CDC) defines SSI as proliferation of pathogenic microorganisms which develops in an incision site either within the skin or sub-cutaneous fat (superficial), musculo-facial layers (deep) or in an organ or cavity if opened during surgery. It occurs […]
DNA replication is the process by which a double-stranded DNA molecule is duplicated, involving the unwinding of the DNA helix, separation of the DNA strands, and the synthesis of complementary strands by DNA polymerase enzymes, resulting in two identical copies of the original DNA molecule.

The lac operon is a genetic system found in bacteria that controls the expression of genes involved in the metabolism of lactose, where the presence of lactose induces the transcription of these genes through the interaction of regulatory proteins with specific DNA sequences.

The central dogma of molecular biology is a fundamental principle stating that genetic information flows from DNA to RNA through the process of transcription, and then from RNA to proteins through the process of translation, forming the basis of gene expression and protein synthesis.

The tryptophan (Try) operon is a genetic system found in bacteria that regulates the production of enzymes involved in the biosynthesis of the amino acid tryptophan, where the presence of tryptophan represses the expression of the operon by binding to a regulatory protein and preventing transcription of the genes.
