Dot blot technique is a method of identifying the presence of DNA, RNA and Protein in the sample. It is the simplified form of Southern, Northern and Western blotting for the isolation of DNA, RNA and protein respectively. This method can detect the presence or absence of biomolecule in a single run. Dot blot technique …
Cytoplasmic inheritance also refers to Maternal inheritance or Maternal effect. In the cytoplasm, autonomous organelles are present like mitochondria and plastids which are having their own genetic material. Mitochondria is present in both animal and plant cell whereas plastids only found in the plant cell. The gamete which contributes the cytoplasm is the female gamete …
Taxonomic categories can define as the hierarchy to classify the different types of individuals into the correct or convenient category by the observable characteristics as there are 1.7-1.8 million species in the living world. There are seven characteristics that are used to classify a particular group of individuals. The seven categories in descending order are …
Arabinose operon is the operon system found in the bacterial cell which is used to breakdown the arabinose. This kind of operon provides energy to the cell by the breakdown of arabinose into Xylulose phosphate. Arabinose provides energy in the form of a carbon source to the bacterial cell. The bacteria utilize this carbon source …
Southern Hybridization is the technique which was first given by the scientist E. M. Southern in 1975. It is a type of blotting method, which involves a transfer of the DNA from the solid agarose gel to the adsorbent medium like nitrocellulose or nylon filter paper. Southern blotting is done after the process of DNA …
Colony hybridization is the method which was first given by the scientists Grinstein and Hogness in the year 1975. This method isolates the specific DNA sequences or genes from the hybrid DNA. Colony hybridization is carried out by the nitrocellulose filter paper. This technique is very much similar to the replica plating. Colony hybridization involves …
Major Difference: The difference Between Budding and Grafting is due to: The part of Scion In budding, a scion is a bud of the closely related plant which is inserted into the rootstock of the original plant. Whereas in the grafting method, a scion is a stem of a closely related plant which is inserted …
The microbial food spoilage is one type of food spoilage that is caused by microorganisms. Food spoilage can define as the process in which the quality of the food deteriorates to some extent which is inconsumable for the person to eat. Food spoilage occurs as a result of the microbial attack, enzymatic digestion, chemical degradation, …
Isolation of bacteria is a primary method to separate different groups of microorganisms. It is the method which helps us to differentiate different groups of organisms. It is the method, which allows us to discriminate different groups of bacteria on the basis of “Growth Pattern”. Different bacteria grow differently on the different nutrient medium based …
The qualitative analysis of Lipids detects the presence or absence of lipid on the basis of colour change. Lipids are the organic biomolecules which are soluble in non-polar solvents like chloroform, ether, acetone etc. and insoluble in water. In nature, there are different varieties of lipids which shows structural diversity among each other. Some common …
