Advantages and Disadvantages of Cell Culture: Tissue culture is an aseptic in vitro culture of animal or plant cells in a precisely controlled environmental condition. The term “Tissue Culture” was for the first time coined by Thomas Burrows. Even though the in vitro culture of prokaryotes and both plant and […]

Restriction Endonucleases Restriction endonucleases (also called as molecular scissors) are a class of nuclease enzymes which cut the DNA strand at precise locations. They are specific endonuclease enzymes in the cells which first recognize the specific sequence (called restriction sites) within the DNA strand and cleave the phosphodiester backbone of […]

ssDNA vs dsDNA The DNA molecules are not always double stranded helical structures, sometimes they occur in single stranded form called ssDNA. In 1959 Robert Sinsheimer discovered a unique bacteriophage called φX 174 (which infect Escherichia coli) with single stranded DNA as its genetic material. Even though the chemical composition […]

We wish to suggest a structure for the salt of deoxyribose nucleic acid (DNA). This structure has novel features which are of considerable biological interest. Watson & Crick, 1953 DNA and RNA are the two types of nucleic acids (a class of macromolecules in the cells) present in all prokaryotic […]

Apoptosis vs Necrosis Apoptosis and Necrosis Apoptosis and Necrosis are two types of cell death occur in organisms. The cells undergo death when the cell death becomes necessary as a part of developmental process or they fail to adapt to injuries. Both these types of cell deaths differ in their […]
