Define Epistasis-Classes, Types, Examples, Significance

Define Epistasis- Classes, Types, Examples, Significance Epistasis is the interaction between two non-allelic genes in which the phenotypic expression of one gene is masked or repressed by the expression of one or more other genes. Mendelian and his collaborators previously assumed that the traits were determined by the expression of a single gene with two … Read more

Define Carbapenem-Resistant Acinetobacter baumannii (CRAB)

Define Carbapenem-Resistant Acinetobacter baumannii (CRAB) Carbapenem-resistant Acinetobacter baumannii (CRAB) is a group of A. baumannii that have evolved resistance to the carbapenems. Acinetobacter is a genus of aerobic, glucose-non fermentative, rod-shaped (specifically Cocco bacilli), gram-negative gamma-proteobacteria in the family Moraxellaceae of the phylum Pseudomonadota. Define Acinetobacter baumannii? Define Acinetobacter baumannii a pathogenic species of this … Read more

Gene Prediction- Importance and Methods

Gene Prediction- Importance and Methods

Gene Prediction- Importance and Methods One of the main topics in bioinformatics is the prediction of genes using computer-assisted methods for the localization of protein-coding regions. Predicting genes essentially means locating genes throughout a genome. Also called gene discovery, it refers to the process of identifying regions of genomic DNA that code for genes. These … Read more

Definition of Pseudocoelomate, Example, Characteristics

Definition of Pseudocoelomate A pseudocoelomate is an organism with a body cavity that is not derived from the mesoderm, as in a true coelom or body cavity. A pseudocoelomate is also known as a blastocoelomate because the body cavity is derived from the blastocoel of the cavity inside the embryo. A true coelom is lined … Read more

What is a central vacuole in a cell? Function, and Role

What is a central vacuole in a cell? The central vacuole is a large vacuole found within plant cells. A vacuole is a sphere filled with liquid and molecules within a cell. The central vacuole stores water and maintains turgor pressure in a plant cell. It also pushes the contents of the cell to the … Read more

Transport Protein Definition, Function, & Example

Transport Protein Definition Transporter proteins are proteins that transport substances across biological membranes. Transport proteins reside within the membrane itself, where they form a transport channel or mechanism to allow their substrate to move from one side to the other. The substances carried by these proteins can include ions such as sodium and potassium; Sugars … Read more

The Pseudostratified Columnar Epithelium

The Pseudostratified Columnar Epithelium The pseudostratified columnar epithelium is tissues made up of a single layer of cells that appear to be made up of multiple layers, especially when viewed in cross-section. The nuclei of these epithelial cells are found at different levels, giving the illusion of being stratified. However, this tissue is made up … Read more

Allosteric Inhibition Definition

Allosteric Inhibition Definition Allosteric inhibition is the slowing down of enzyme-catalyzed chemical reactions that take place in cells. These metabolic processes are responsible for the proper functioning and maintenance of balance in our body, and allosteric inhibition can help regulate these processes. Essentially, metabolic processes break down and important molecules are formed. They are essential … Read more

Selective Permeability Definition, &Function

Selective Permeability Definition Selective permeability is a property of cell membranes that only allows certain molecules to enter or leave the cell. This is important for the cell to maintain its internal order regardless of changes in the environment. For example, depending on metabolic activity, water, ions, glucose, and carbon dioxide must be imported or … Read more

Glycogenolysis definition, Function of Glycogenolysis

Glycogenolysis definition Glycogenolysis is the breakdown of the glycogen molecule into glucose, a simple sugar that the body uses for energy. Glycogen is essentially energy stored in the form of a long chain of glucose, and glycogenolysis occurs in muscle and liver cells when more energy needs to be produced. The opposite of glycogenolysis is … Read more
