Southern Blotting: Principle, Steps involved and Applications
Southern blotting also called Southern hybridization is a hybridization technique which helps to detect specific gene sequences or DNA fragments within complicated mixture of nucleic […]
DNA sequencing by Sanger’s method
DNA sequencing is the process of determining the entire sequence of nucleotides of a genome. The development of new techniques has made it possible to […]
Structure and Functions of three major types of Ribonucleic Acid (RNA)
RNA is a type of nucleic acid found inside living cells. It is a polymer of ribonucleotides. One molecule of ribonucleotide consists of: Ribose sugar […]
Bacterial transduction and its types
Transduction is the transfer of gene or portion of DNA from one bacterium (donor) to another (recipient) mediated by a bacteriophage. In transduction, the bacteriophage […]
Mutation and its types
Mutation can be defined as any inheritable changes in the sequence of nitrogenous bases of DNA that brings about sudden change in the morphological characteristics […]
Plasmids, their types and functions
Plasmids are extra-chromosomal DNA. They are circular and double stranded DNA molecules which encode traits that are not essential for bacterial viability (normal growth and […]
