information about cells

The flow of information in the living cells involves two mechanisms. One of them is the flow of genetic information contained in the DNA. This information, which is responsible for all cellular activities, is present in the form of a specific sequence of nucl..

Living cells constantly exchange energy and materials with their surrounding environment. The functioning of living cells depends upon the flow of energy and flow of information..

. In 1858, a German biologist Rudolph Virchow found that all living cells arise from pre-existing cells ('omniscellula e cellula'). In 1866 Ernst Haeckel suggested that nucleus might store and transmit the hereditary information. The improvement made in the field of mi..

Introduction - One of the main ideas in the modified cell principle is that new cells arise from pre-existing cells (Omnis cellula e cellula). Every new cell formed must inherit not only the nucleus which contains the genetic information, but also s..

Summary - According to the modified cell principle, new cells arise only from pre-existing cells. Cells transfer their genetic information only by way of cell division. The mode of cell division is largely the same in all living ..

Mutations are sudden heritable changes brought about by the composition of a gene or a chromosome. Accordingly, it can be a gene mutation or a chromosomal mutation. Sometimes, there may be just a change in the chromosome number causing a variation. It is called as ploidy or genomatic mutation. All..

Organisms look similar because their body designs are similar. If body designs are to be similar, the blue prints for these designs should be similar. Thus, reproduction involves making copies of the blueprints of body design. The chromosomes in the nucleus of a cell contain informa..
