Phytase, an enzyme produced by Aspergillus niger can be adsorbed on microcrystalline cellulose powder (MCCP). The adsorption follows a Langmuir isotherm and the maximum concentration of the protein that can be obtained on the adsorbent is 70 mg cm-1. At a concentration of 50 mg L-1 of protein in the solution, the concentration of protein on the adsorbent reaches 35 mg cm-1. It is desired to recover 90% of the protein from 1.5 liter of the cell free culture filtrate containing 220 mg L-1 protein by addition of MCCP to the solution. The concentration of the protein adsorbed on the solid at equilibrium will be:

Which set of the following events occurs during the elongation step of translation?
P. Attachment of mRNA with the smaller subunit of ribosome
Q. Loading of correct aminoacyl-tRNA into the A site.
R. Formation of a peptide bond between the amino acyl-tRNA in the A site and the peptide chain that is attached to the peptidyl-tRNA in the P site.
S. Dissociation of the ribosomal subunits.
T. Translocation of peptidyl-tRNA from the A site to the P site of the ribosome.
Directions : In each of the following questions a statement is given, followed by two conclusions. Give answer :

Statements : About 50 per cent of the animal by-products - hair, skin, horns etc. is edible protein. American chemists have developed a method of isolating 45 per cent of this protein. They used an enzyme developed in Japan to break down soya protein.

Conclusions :
I. Americans have not been able to develop enzymes.
II. Animal by-products protein has the same composition as soya protein.

2. The third stage of the cell cycle is termed G2 phase
3. In the mitotic phase, the DNA molecule of each chromosome replicates by the synthesis of a new DNA molecule on the template of the existing DNA
Given below are six sentences, four of which (P,Q,R,S) are jumbled. Pick the option that gives the correct order of P,Q,R,S. 1 The site proposed at Miyapur is located close to the main road. P - The title deed of the land is clear and no litigation is envisaged. Q - Further, as there is a shopping complex close to the site, water and electricity may not be a problem. R - Firstly, it is easily accessible as it well connected to various parts of the city by three bus routes. S - Most important of all, the building adjacent to the site is also available on lease. 6 There is scope for expansion of the office as a plot of land on the north of the proposed site is a vacant at present.
