Southern blotting is a molecular biology technique used to detect specific DNA sequences in a sample. It involves digesting DNA, electrophoresis, transferring the DNA to a membrane, and then using a labeled probe to hybridize and identify the target DNA sequence. This technique is named after its inventor, Edwin Southern. […]
pBR322 is a well-known plasmid DNA used in molecular biology and biotechnology. It was one of the first plasmids developed for cloning and genetic engineering. pBR322 contains genes for antibiotic resistance and multiple cloning sites, making it a valuable tool for DNA manipulation and recombinant DNA studies. This is an […]
Photosynthesis is the biological process by which green plants, algae, and some bacteria convert sunlight, water, and carbon dioxide into glucose (a form of sugar) and oxygen. This process occurs in chloroplasts and is essential to produce energy-rich molecules, supporting the growth and sustenance of life on Earth. This is […]
A TI (tumour-inducing) plasmid is a type of circular DNA molecule found in certain strains of the bacterium Agrobacterium tumefaciens. It plays a crucial role in the bacterium’s ability to infect plants and transfer genes into them, causing the formation of crown gall tumours. TI plasmids have been extensively studied […]
Pyrimidine synthesis is a biochemical pathway to produce pyrimidine nucleotides, which are key components of DNA, RNA, and molecules like ATP and UTP. It involves a series of enzymatic reactions that convert precursor molecules into pyrimidines, such as cytosine, thymine, and uracil, essential for genetic and metabolic processes. This is […]
