DMPQ: Describe the cell structure with the help of suitable diagrams and functions of the cell

by

Cell structure and its functions Cell is the smallest structural and functional unit of an organism, which is typically microscopic and consists of cytoplasm and a nucleus enclosed in a membrane. Structure of cell The cell is a basic unit for life forms. As well as enabling sophisticated control of biochemical processes by providing compartments … Read more DMPQ: Describe the cell structure with the help of suitable diagrams and functions of the cell

DMPQ-Write a short note on somatic cell nuclear transfer.

by

SCNT is a laboratory technique for creating an ovum with donor nucleus. In it, nucleus containing the organism’s DNA of somatic cell (a body cell other than sperm or egg cell) is removed and rest of cell discarded. The nucleus of somatic cell is then inserted into enucleated egg cell which reprograms somatic cell nucleus … Read more DMPQ-Write a short note on somatic cell nuclear transfer.

DMPQ- Discuss the role of chromosomes during cell division.

by

Mitosis When the chromosomes condense during cell division, they have already undergone replication. Each chromosome thus consists of two identical replicas, called chromatids, joined at a point called the centromere. During mitosis the sister chromatids separate, one going to each daughter cell. Chromosomes thus meet the first criterion for being the repository of genes: they … Read more DMPQ- Discuss the role of chromosomes during cell division.

Dry Cell

by

 Dry cell A dry cell is an electrochemical cell that uses a low-moisture electrolyte instead of a liquid electrolyte as a wet cell does. This feature makes the dry cell much less prone to leaking and is therefore more suitable for portable applications. The zinc-carbon battery is one of the most common examples … Read more Dry Cell

DMPQ: What is fuel cell? How Hydrogen fuel cell work? ( SCIENCE)

by

A fuel cell is a device which produces electric energy, through a chemical reaction. Fuel cells use positively charged ion(Hydrogen) and an oxidising agent (oxygen).There are many types of fuel cells, but they all consist of a cathode,an anode, and an electrolyte that allows positively charged( hydrogen) ions to move between the two sides of … Read more DMPQ: What is fuel cell?

DMPQ: Micropropagation, Somatic hybridisation, Single cell protein, Mutation breeding

by

Micropropagation Ans:  Method of producing thousands of plants through tissue culture is called micropropagation. Each of these plants will be genetically identical to the original plant from which they are grown. They are soma clones. Somatic hybridisation Ans:  In somatic hybridisation cell wall is removed by digesting it with enzyme like pectinase and cellulase. Isolated … Read more DMPQ: Micropropagation, Somatic hybridisation, Single cell protein, Mutation breeding
