RNA which carry amino acid from the cytoplasm to the ribosome is:

HIV mainly attacks

A circular disc of radius 'R' has uniform thickness. A circular hole of diameter equal to the radius of the disc has been cut out as shown. The centre of gravity of the remaining part of the disc lies on the diameter of the disc at a distance to the left of the centre of the original disc, which is equal to:

The type of isomerism shown by the complex [CoCl₂(en)₂] is:

A proton, a deuteron, and an α -particle is projected perpendicular to the direction of a uniform magnetic field with the same kinetic energies. The ratio of the radii of the circular paths described by them is -

In which one of the following processes CO₂ is not released?

A particle starts from the rest with a constant acceleration. At time ′t′ seconds, the velocity is found to be 200m/s and one second later, the velocity becomes 250m/s. Calculate the acceleration and the distance travelled during (t+1)^th second.

(NH₄)₂Cr₂O₇ gives on heating a gas which is also given by:

A double-slit apparatus is immersed in a liquid of refractive index 1.33. It has slit separation of 1mm and distance between the plane of slits and the screen is 1.33m. The slits are illuminated by a parallel beam of light whose wavelength in air is 6300 What is the fringe width?
