Introduction Transposons are a type of mobile genetic element in which DNA sequences have a unique ability to move from one place to another within a chromosome. Eukaryotes have transposons that are structurally similar to bacterial transposons and some similar transposition mechanisms. In other cases, however, the mechanism of transposition ... Read More

Introduction Restriction sites are the unique sites on the DNA that are recognized by restriction enzymes and then cleaved into smaller fragments. They are also called recognition sites. These restriction sites and their recognition has revolutionized the field of genetic engineering ad cloning techniques. Several molecular markers are developed based ... Read More

Introduction Genetic markers can be defined as a sequence of DNA with a known physical location on a chromosome. Genetic markers and genes that are close to each other tend to get inherited together. Genetic markers vary between individuals to the extent they can be used to help find a ... Read More

Introduction Radiation can be defined as a form of electromagnetic wave that can travel through a vacuum or any other medium. They have both particles as well as wave nature. Since they can travel in a vacuum so, they can travel through space and can reach us and can even ... Read More

Introduction It was earlier described by Beadle and Tatum that a gene is the part of DNA that determines or codes the primary sequence of some final gene product which can be an enzyme, a polypeptide, or an RNA. On the other hand, as the name suggests, pseudogene or false ... Read More

Introduction Living organisms produce a variety of proteins for various functions. The type of protein to be produced depend on the function it has to perform, the need of the protein, and its interaction with other proteins. This entire set of proteins that are produced in a living system is ... Read More

Introduction Proteins are known as the basic body-building macromolecules in our body. Since they are required in more quantity in our body like carbohydrates and lipids, they are called macromolecules. Proteins are made up of monomeric units called amino acids to form polymeric proteins. So, we can say that amino ... Read More

Introduction Bacteriophages replicate themselves by two pathways which are the lytic and lysogenic cycles. Both cycles differ from each other in the fact that in the lytic phase bacteriophage assembles its particles and causes the rupturing of the host bacteria whereas, in the case of the lysogenic cycle, the phage ...

Introduction Radio isotopic hybridization techniques have been used for many years for the detection of DNA and RNA fragments from a mixture of molecules. But radio isotopic hybridization techniques are more hazardous as they cause harm to the person in the vicinity by activating cancerous cells and causing harm to ... Read More

Introduction Once Theodosius Dobzhansky quoted that “Nothing in biology makes sense except in the light of evolution.” This generalization has been validated by recent progress in Biochemistry and Molecular biology. The remarkable similarity of metabolic pathways and gene sequence across the phyla argues strongly that all modern organisms are derived ... Read More
