need for differentiation

A differential equation is said to be linear, if the unknown function and its derivatives occur only in the first degree and are not multiplied together. Example: Note that the degree of a linear differential equation is 1, but a differential equation whose degree ..

. These results indicate that: Some changes occurs in the nuclei of cells during differentiation. Differentiation does not result in the loss of, or permanent inactivation of, the genes; in fact it turns off the genes in a reversible manner. This means that a differentiated..

g (x, y, y', a, b) = 0 .(5) We can not eliminate a and b from equation (4) and equation (5). Therefore we need another equation which can be obtained by differentiation equation (5). Differentiating equation (5) with respect to x, we have h(x, y, y ',y'', a, b) = 0 .(..

During post embryonic growth, and also in the adult, all the body cells are not capable of undergoing division. This is because they have become differentiated. But at some locations, undifferentiated cells are present which divide mitotically and replace the worn out differentiatedh..

Advantage of the Regulation of Gene Action - An operon is the unit of transcription. When excess protein is present, it is no longer economical for the cell to use up its energy and materials in the synthesis of enzymes that are not immediately needed. Hence, the protein synthesis is stop..

Tissue culture is based on the concept of cellular totipotency. That is all the multicellular organisms basically are formed from a single cell (the zygote), by repeated multiplication and differentiation. Thus a single cell can develop into a whole organism or in other words, the cell i..

These are land plants which grow in moist habitats and need well aerated soils. They prefer soil and air with moderate humidity. They avoid soils with standing water and soils containing great abundance of salts. They have some special features. Root system is well developed. Stems are ge..

TutorVista's online Calculus help isn't just about working out a few problems and logging off. Features like regular homework help, and exam prep enable a student to get all the help he/she needs. There is also an extensive library of e-learning material like free Calculus question banks..

. Thus a single cell can develop into a whole organism or in other words, the cell is totipotent. This is because it contains the full set of genetic information needed to make the organism. This is called cellular totipotency. Thus, a tissue can be taken from any part of the plant and pu..

Gene Regulation in Eukaryotes - In eukaryotes, the genes that code for the enzymes needed to catalyse the various steps of a particular metabolic pathway may not be adjacent or even be in different chromosomes. However, these genes are regulated by operon model as in bacteria. Both the in..
