Mohan is an agricultural labourer. There are several months in a year when he has no work and needs credit to meet his daily expenses. He depends upon his employer, the landowner for credit which charges an interest rate of 5 per cent per month. Mohan repays the money by working physically for the landowner on his farmland.Over the years his debt will
In living cells, such as E. coli, the process of replication requires a set of catalysts (enzymes). The main enzyme is referred to as DNA-dependent DNA polymerase, since it uses a DNA template to catalyse the polymerisation of deoxynucleotides. These enzymes are highly efficient enzymes as they have to catalyse polymerisation of a large number of nucleotides in a very short time. E. coli that has only 4.6 ×106 bp), completes the process of replication within 18 minutes; that means the average rate of polymerisation has to be approximately 2000 bp per second. Deoxyribonucleoside triphosphates serve dual purposes. In addition to acting as substrates, they provide energy for polymerisation reaction (the two terminal phosphates in a deoxynucleoside triphosphates are high-energy phosphates, same as in case of ATP). In addition to DNA-dependent DNA polymerases, many additional enzymes are required to complete the process of replication with high degree of accuracy.
A metal complex having composition Cr(NH3)4Cl2Br has been isolated in two forms (X) and (Y). The form (X) reacts with AgNO3 to give a white precipitate readily soluble in dilute aqueous Ammonia, whereas (Y) gives a pale-yellow precipitate soluble in concentrate ammonia.
A point charge q is placed within the cavity of an electrically neutral conducting shell whose outer surface has spherical shape figure. Then:
Two identical stars of mass M orbit around their centre of mass. Each orbit is circular and has radius R, so that the two stars are always on opposite sides of the circle, the velocity of each body is..
A solid cylinder of mass 2 kg and radius 50 cm rolls up an inclined plane of angle inclination 30°. The centre of mass of cylinder has speed of 4 m/s. The distance travelled by the cylinder on the incline surface will be : Take g=10m/s2
