Transposons: Features, Types and Mechanism

A transposon, also known as a “jumping gene,” is a segment of DNA that can move or “transpose” itself to different positions within the genome of a single cell. This ability to change positions makes transposons significant contributors to genetic diversity and evolution. Features of Transposons: Also Known as: Jumping gene or Mobile elements. • … Read more

Molecular Techniques

Molecular techniques are methods used to analyze and manipulate DNA, RNA, and proteins to study biological processes. • Blot: In molecular biology, blot is a technique for transferring DNA, RNA or proteins onto a carrier or membrane so they can be separated by use of gel electrophoresis. • Probe: A short single stranded DNA which … Read more

Restriction Enzymes

Restriction enzymes are proteins that cut DNA at specific sequences, used for DNA manipulation in genetic engineering and molecular biology. Example: EcoR I, EcoR ll, BamHI, Hind III Nomenclature:  Each restriction enzyme is named after the bacterium from which it was isolated, using naming system based on bacterial genus, species and strain. Example: EcoRI Recognition … Read more
