The ovule is a part of a plant that is popularly known as megasporangium. It is present inside the ovary base, which extends and gives rise to the stalk-like structure called style and finally opens into the stigma. Megasporangium can be defined as a large, sac-like structure, which gives rise to the production of the megaspores …
Phototropism in plants is a process where a plant bends in response to sunlight or any other light source. Plants sense light stimuli through their photoreceptors proteins. These specialized protein molecules or photoreceptors form a complex with the light-absorbing pigment (chromophore). When a chromophore absorbs light radiations, it brings changes in the photoreceptors’ structural configuration …
The concentration of ore is a method of eliminating gangue particles or other impurities. Ore-dressing and benefaction are the alternative names for the term concentration of ore. To obtain a pure metal from ore, the method of ore concentration is a very crucial step. For the extraction of metal, it is necessary to separate ore …
Microbial interaction is a biological interaction where the microorganisms’ effect on the other biotic components of the ecosystem can be studied. The study of microorganisms is termed microbiology, and the microbial interacting within the ecosystem comes under microbial ecology. Microbial interaction can be positive and negative, or the microbes may affect (positively or negatively) the …
The difference between the small intestine and large intestine is mainly due to the three factors like length, diameter and involvement in the digestion. Both small and large intestine belongs to the intestinal system. Length: The small intestine’s length is 9 m that is larger than the large intestine whose length is about 1.5 m. …

Dot blot technique is a method of identifying DNA, RNA and Protein in the sample. It is the simplified form of Southern, Northern and Western blotting for DNA, RNA, and protein isolation, respectively. This method can detect the presence or absence of biomolecule in a single run. Dot blot technique is a prevalent method in …
Cytoplasmic inheritance also termed as maternal inheritance or maternal effect. A cytoplasm comprises some autonomous organelles like mitochondria and plastids that possess their own genetic material. Mitochondria is present in both animal and plant cell, whereas plastids are only found in the plant cell. As we know, nucleic acids like DNA and RNA are responsible …
Taxonomic categories can define as the hierarchical classification of the different individuals into a more specific sequence by categorizing them into seven categories starting from the origin to the organisms. The taxonomic category was first given by the scientist Carl Linnaeus in the 18th century. Linnaeus also developed a system called binomial nomenclature. Linnaean hierarchy, …
Arabinose operon is one of the regulatory systems found in the bacterial cell (E.coli), facilitating arabinose catalysis. L-arabinose operon and ARA-operon are the two alternative names of the arabinose operon. Ara-operon system provides energy to the cell by the breakdown of arabinose into xylulose 5-phosphate. Arabinose is a 5-C sugar or aldopentose that provides energy …
Southern hybridization is the technique, first given by the scientist E. M. Southern in 1975. It is a type of blotting method that involves transferring the DNA from the solid agarose gel to the adsorbent medium like nitrocellulose or nylon filter paper. Southern blotting is done after DNA hybridization. The target DNA is first cleaved …
