Lentiviral transfection is a method for introducing genetic material into cells. It involves the use of lentiviruses, a type of retrovirus, to deliver the desired DNA into the target cells. Lentiviral transfection has a unique advantage over other transfection methods, in that it can infect both dividing and non-dividing cells, making it useful for a … Read more
Post-glycolysis processes Glycolysis is a process that involves: Glucose + 2 NAD+ + 2 ADP + 2 Pi → 2 pyruvate + 2 NADH + 2 H+ + 2 ATP Glycolysis could not continue indefinitely if all NAD+ was used up and glycolysis would cease. Organisms must be capable of oxidizing NADH back into NAD+ … Read more
What is Isomerism? Definition of Isomerism Isomerism is the phenomenon in chemistry where molecules or ions have the same molecular formula but differ in their spatial arrangement or bond connectivity. Different Types of Isomerism Isomerism, a fundamental concept in chemistry, can be classified into two primary types: structural isomerism and stereoisomerism. Let’s delve into these … Read more
Standard protein expression systems, including E. coli, frequently fail to generate folded, monodisperse, or functional eukaryotic proteins (see Small-scale Expression of Proteins in E. coli). Utilizing a eukaryotic system, such as mammalian cells, that includes the required folding and posttranslational machinery is highly advantageous for the expression of these proteins. Using polyethylenimine, we present strategies … Read more
Cell division is a crucial process that allows organisms to grow, repair, and reproduce. One important aspect of cell division is cytokinesis, the process of separating one cell into two daughter cells. While cytokinesis is a universal process, it can vary greatly between different types of cells. In this article, we will compare and contrast … Read more
What is Phytoremediation? Types of Phytoremediation There are three varieties of phytoremediation: 1. In situ phytoremediation Advantages of In situ phytoremediation Disadvantages of In situ phytoremediation 2. In-vivo phytoremediation with relocated contaminants 3. In vitro phytoremediation Processes Of Phytoremediation Phytoremediation is based on certain natural processes carried out by plants, such as: Mechanisms of phytoremediation … Read more
What is Parasitism? Definition of Parasitism Parasitism is a symbiotic relationship between two species in which one organism, the parasite, derives benefits at the expense of the other organism, the host, often causing it harm. Mechanisms of Dispersal Types of Parasitism Parasitism, a multifaceted biological interaction, can be classified based on various criteria, ranging from … Read more
Definition of Biotic Factor Biotic factors are the living components or variables that have an effect on an ecosystem or other species residing in that ecosystem. Biology definition A biotic factor is a factor produced by a live organism or any living component in its surroundings as a result of the organism’s actions. Biotic factors … Read more
What is Bioaccumulation? Definitions of Bioaccumulation Bioaccumulation (increase in chemical concentration) is the process of chemical accumulation in an organism over time. Bioaccumulation, as defined by the International Union of Pure and Applied Chemistry, is the accumulation of a chemical in an organism due to direct uptake from the environmental matrix (bioconcentration) and uptake from … Read more
