Biotechnology and its Application

Biotechnology revolutionizes industries and human life through its innovative applications. From healthcare to agriculture, biotechnology harnesses biological systems and organisms to develop products and processes that improve human welfare.

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
