Thermosetting polymers made from relatively low molecular mass semi-fluid polymers which when heated in a mould forms an insoluble hard mass which is infusible. This is due to extensive crosslinks between the different polymer chains forming three dimensional network of bonds. ..

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 inducible and the repressibl..

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 nucleu..

Bonding in Covalent Solids - In covalent solids, the constituent particles are atoms of same or different kinds. Covalent bonds network, forming a continuous giant interlocking structure of atoms throughout the crystal that hold them together. They are also referred to as covale..

In covalent crystals, the constituent particles are atoms of the same or different kind, which are bonded to one another by a network of covalent bonds. The important characteristics of covalent crystals are: The covalent crystals are incompressible and hard. They are extr..
