Assertion : DNA is associated with proteins. Reason : DNA binds around histone proteins that form a pool and the entire structure is called a nucleosome.

Go through the following statements: (i) a typical nucleosome contains 400 bp of DNA helix. (ii) The positively charged DNA is wrapped around the negatively charged histoned octamer to form a structure called nucleosome. (iii) Histones are rich in the basic amino acid residues asparagine ad valine (iv) The packaging of chromatin at higher level requires additional set of proteins that collectively are referred to as nonhistone chromosomal proteins.

Go through the following statements (i) In geometric growth, following mitotic cell division, only one daughter cell continues to divide while the other differentiates and mature. (ii) The ability of plants to follow different pathways in response to environment or phases of life to form different kinds of structures, is called plasticity. (iii) The mathematical expression for arithmetic growth is Lt = L_0 + rt while for geometric growth, it is W_1=W_0=W_(0)e^(rt) (iv) The form of growth wherein new cells are always being added to the plant body by the activity of the meristem, is called the open form of growth. Which of these are correct .

In a hexaonal system system of cycstals, a frequently encountered arrangement of atoms is described as a hexagonal prism. Here, the top and bottom of the cell are refular hexagons, and three atoms are sandwiched in between them. A space-cilling model of this structure, called hexagonal close-paked is constituted of a sphere on a flat surface surrounded in the same plane by six identical spheres as closely as possible. Three spherres are then placed overt the first layer so that they toych each other and represent the second layer so that they toych each other and present the second layer. Each one of the three spheres touches three spheres of the bottom layer. Finally, the second layer is convered with a third layer identical to the bottom layer in relative position. Assume the radius of every sphere to be r . The voume of this hcp unit cell is
