These are very fine thread-like, coiled filaments uniformly distributed in the nucleoplasm. At the time of cell division, the chromatin becomes thick and ribbon like and are known as chromosomes. The chromosomes contain genes, which are composed of DNA (deoxy-ribonucleic acid). Genes are responsib..

This is a prominent, spherical or oval structure found at the centre of the cell. It is the controlling centre of all cell activities and has been described as the brain of the cell. It regulates all metabolic and hereditary activities of the cell. The nucleus is composed of the following structur..

The cardiac muscle fibres do not form fasciles. They are arranged in the form of a network. The muscle fibres are elongated, cylindrical and branched. The branches become inter-connected with one another to form a network. The space between the muscle fibres is filled with..

At each pole, the gathering chromosomes become less distinct as they merge into a network The nucleolus reappears at each pole. A newly formed nuclear membrane encloses the chromatin network. Thus two daughter nuclei are formed. The number of chromosomes in each daughter nucleus..

In long-distance lines, losses are so high that satisfactory operation becomes impossible without the use of amplification. Amplifiers for telephone service are known as repeaters, and they must of course function in both directions along the line. Repeater stations are ordinarily installed at 50-m..

Within the nuclear membrane, completely filling up the space, is a clear, semi-solid, granular substance or matrix called the nucleoplasm. The nucleolus and the chromatin network lie suspended in the nucleoplas..

Chromosomes at each pole uncoil and elongate to form chromatin. Nucleolus and nuclear membrane are formed surrounding each chromatin network. Asters and spindle fibres disappear and centrioles divide. Daughter nuclei are forme..
