What happens in the absence of tryptophan? When tryptophan is plentiful, two tryptophan molecules bind the repressor protein at the operator sequence. This physically blocks the RNA polymerase from transcribing the tryptophan genes. When tryptophan is absent, the repressor protein does not bind to the operator and the genes are transcribed. What does tryptophan do […]
What is the principle of an electric generator?
What is the principle of an electric generator? Electric generators work on the principle of electromagnetic induction. A conductor coil (a copper coil tightly wound onto a metal core) is rotated rapidly between the poles of a horseshoe type magnet. The conductor coil along with its core is known as an armature. What is the […]
What is oxidation number of PbO?
What is oxidation number of PbO? +4 What is the name of VO2+? Vanadium(IV) oxide or vanadium dioxide is an inorganic compound with the formula VO2. It is a dark blue solid. Vanadium(IV) dioxide is amphoteric, dissolving in non-oxidising acids to give the blue vanadyl ion, [VO]2+ and in alkali to give the brown [V4O9]2− […]
Which wavelength is scattered the most by the atmosphere?
Which wavelength is scattered the most by the atmosphere? blue light Which color has more refractive? violet colour Which color of light has the most energy? violet For which Colour refractive index is minimum? Refractive index of a color is inversely proportional to the wavelength of the color. The wavelength of red color is longer […]

Which force is being applied by the boy is hitting a ball with a bat? gravitational force What is proof load in spring? Proof load is the maximum load carrying capacity of the spring, without getting permanently distorted. What is proof ammunition? A “proof round” is an ammunition assembly designed to be used in proof […]
What would happen if the moon lost mass?
What would happen if the moon lost mass? A less massive moon would also orbit closer to Earth than the real one. This makes it spiral a little farther outward with every orbit around Earth. (Each lunar revolution takes about 29.5 days). If the moon were half its mass, then the ocean tides would have […]
