What is Cancer Biotechnology?
Cancer is a genetic or hereditary disease. It is a disease characterized by variations of the genome and the proteome. Its controls include prognostic diagnosis, differential diagnosis, early detection, and...

Spectroscopy: Definition, Theory And Its Types
Spectroscopy is simply the study of the interaction of electromagnetic radiation and matter as a function of the wavelength or frequency of the radiation. It is the detailed study of...
Transfer RNA: Structure and Function (tRNA)
Transfer RNA commonly abbreviated as tRNA are adaptor between codons and amino acids. The heart of protein synthesis is the “translation” of nucleotide sequence information into amino acids. Each codon...
Phagocytosis – Principle, Mechanism and Process
Phagocytosis refers to the process in which a cell engulfs a large particle by extending its plasma membrane. This gives rise to an internal compartment called the phagosome inside which...
Transmission Electron Microscopy or TEM
Transmission electron microscopy or TEM is a microscopy technique in which a beam of highly focused electrons is directed towards a thin section of the specimen (<200 nm) and allowed...
Scanning Electron Microscope: Working, Principle & Parts
SEM stands for Scanning Electron Microscope. In this article, we will throw some light on the principle and working of the scanning electron microscope. Introduction To begin with, the image...
Flow cytometry: History, Components, Applications
Visualizing and identifying cells by microscopy is not enough. So, a way to quantify phenotypic differences in live cell mixtures on the basis of biological markers is needed. Therefore, flow...
Difference between SEM and TEM
Electron microscopes are of two types namely, Scanning electron microscope (SEM) and Transmission electron microscope (TEM). We will further discuss the difference between SEM and TEM. Introduction Before digging deeper...
Ribosomes: The Protein Factory Of The Cell
A ribosome is an intercellular structure made of both RNA and protein. It is the cellular machinery responsible for protein synthesis. Ribosomes are also called “protein factories” of the cell....
The Centrifuge – Definition, Principle, Types and Applications
The centrifuge is an electrical device that separates various components in a fluid-rising centrifugal force. It is generally driven by an electric motor that puts an object to rotate around...
