Working and application of biosensors ?

Shiv Prakash answered  •  Jan 29, 2019
A biosensor is a biological detection system consists of a biological component combined with a transducer to perform measurement of a biochemical quantity. The development of biosensors started with the invention of enzyme electrodes by Leland C. Clark in 1962.

A typical biosensor includes a bioelement such as an enzyme, antibody, or a cell receptor, and a sensing element or a transduc... more

Measuring parameters of growth in animal biotechnology
?

Aakash Pandey answered  •  Jan 05, 2019
Animal cells are more difficult to culture than microorganisms because they require many more nutrients and typically grow only when attached to specially coated surfaces. Despite these difficulties, various types of animal cells, including both undifferentiated and differentiated ones, can be cultured successfully.

NNitrogen cycle ?

Aakash Pandey answered  •  Dec 28, 2018
Nitrogen is both the most abundant element in the atmosphere and, as a building block of proteins and nucleic acids such as DNA, a crucially important component of all biological life. The nitrogen cycle is a complex biogeochemical cycle in which nitrogen is converted from its inert atmospheric molecular form (N2) into a form that is useful in biological processes.

Why Animal cell culture is more prone to contamination by microbes and their measure to prevent?

Aakash Pandey answered  •  Dec 24, 2018
The microbial contamination of animal cell culture, including stem cells, such as the blood stem cells, is a common problem of cell culture laboratories. It is important to identify the types of microorganisms commonly contaminating the cell culture and the sources of contaminating microorganisms, as well as see their effects on cells in culture. This mini review provides a short account of common... more

Why we are Taq.polemerase enzyme at the time of DNA transcription.?

Roopal Bansal answered  •  Dec 24, 2018
It is isolated from a heat-loving bacterium that is naturally found in hot springs, so the enzyme doesn't break down at the high temperatures necessary for copying DNA using a polymerase chain reaction. At high temperatures, Taq polymerase attaches nucleotides to a DNA template, thereby copying the DNA.

Short notes on GERL system
?

Pushkar Malik answered  •  Nov 17, 2018
The acronym "GERL" stands for Golgi - Endoplasmic Reticulum - Lysosomal complex. These organelles form a system that when combined with the endocytotic and exocytotic pathways provide a means by which the cell can. 1. process endocytosed and synthesized materials, 2. "

Wich type of enzyme use in protoplast isolation?

Rachika Grewal answered  •  Nov 15, 2018
Protoplast Isolation.
Protoplasts are cells which have had their cell wall removed, usually by digestion with enzymes. Cellulase enzymes digest the cellulose in plant cell walls while pectinase enzymes break down the pectin holding cells together.

Difference between eucarpic thallus and holocarpic thallus ?

Shahbaaz Ahmed answered  •  Jun 14, 2018
Diffrence between Holocarpic and Eucarpic

1. Holocarpic Denoting a fungus in which the entire thallus is differentiated into a reproductive sporangium when mature. 
Eucarpic Denoting a fungus in which the thallus is differentiated into vegetative and reproductive regions. 

Holocarpic (Holocarpism)
Whole thallus of fungus becomes converted into a reproductive cell*

Found among:
1. Chytridiomycota
2. Hyphochytridiomycota
3. Plasmodiophoromycota
4. Oomycota
5. Ascomycota
6. Basidiomycota**
7. Fungi imperfecti

2. Eucarpic (Eucarpism) Thallus
- differentiates into distinct vegetative and reproductive portions
- found among all divisions

trends to complexity (hyphal construction)
1. Monocentric (monocentrism)
Thallus consists of single reproductive cell attached to
substrate hyphae
