Exp:A Spindles are formed by microtubule. They are bipolar fibrous in structure that are composed mainly of microtubule. They are composed of tubulin protein. Spindles arise from centriole in animal cell. Spindles forms during cell division to divide sister chromatids between daughter cells. They include the spindle microtubles, associated proteins.

Balbiani rings are the centre for
1 DNA synthesis
2 RNA synthesis
3 Both (a) and (b)
4 None of the above
Explanation:
Exp:B Balbiani rings are the centre for RNA and Protein synthesis. Polytene chromosomes were fist observed by Balbiani (1881) chironomus (dipteran larva) and also called salivary chromosomes because have been seen salivary gland of larvae. They are large puffs on the polytene chromosome. These puffs are suited to studies of the active gene and transport of specific RNA protein particles. They are ring like in the structure.

The nucleus is separated from surrounding cytosplasm by a nuclear membrane, which is
1 single layered with pores
2 single layered without pores
3 double layered with pores
4 double layered without pores
Explanation:
Exp:C Nuclear membrane, which is double layered with pores that separates the nucleus from cytoplasm of cell. The nuclear pore complex are very specific and made up of 30 different protein called nucleoprotein. The nuclear pore complex is help in transport of material from nucleus to cytoplasm and vice-versa.

Balbiani rings are the structural features of
1 allosomes
2 autosomes
3 polytene chromosomes
4 Lampbrush chromosomes
Explanation:
Exp:C Balbiani rings are the structural features of polytene chromosomes. Balbiani rings are locations for RNA synthesis, Which are found on the polytene chromosome in the form of large puffs in the diptera Chironomus tentans. These puffs help to studies of the structure of active genes, and transport of structure of active genes, and transport of specific RNA-protein (RNP) particles.
