B-cells are an integral part of the adaptive immune system. This article delves into B-cell structure, developmental pathways, the dynamic interaction between B-cells and T-cells, and antibody production as part of the immune response against pathogens. Immunity conferred by B-cells is called humoral immunity, since the B-cells originate and mature in the the bone marrow… Continue reading Understanding B-Cells: Key to Humoral Immunity
The liver is a complex organ that carries out many different functions in the body. The liver is divided into lobes, each lobe is divided in hexagonal lobules, with a rich blood supply. The basic structure of the liver is made up of a single type of cell, called hepatocytes. Figure 1: Schematic showing cross-section… Continue reading Biology Biteables – Liver Structure and Function
An Operon is a collection of genes, which perform a similar function. The Lac Operon controls the uptake and metabolism of Lactose. It is found in prokaryotes, such as E. coli. The Lac Operon consists of a Lac I gene (Repressor), a Promoter, an Operator, and three genes - Lac Z, Lac Y and Lac… Continue reading Biology Biteables – Lac Operon
Transcribe: To copy something Transcription is a biological process by which information stored on a gene is copied to a short molecule called messenger RNA. A gene can be divided into two sections: - a Promoter region, which includes a sequence (TATA box), that can be recognised by the active site of the enzyme RNA… Continue reading Biology Biteables – Transcription
