Answer:
The correct option is <em>B) ultraviolet region, especially below a wavelength of 320 nm.</em>
Explanation:
Ultraviolet light carries an enormous amount of energy in it. It is invisible to the human eye. When UV light with enormous energy and wavelength lesser than 320nm, hits the DNA, it causes changes in the structure of the DNA. Mostly, it affects the thymine nitrogenous base regions and forms pyrimidine dimers. The structure of the DNA changes on all the sites where dimers form and hence, they cannot be properly transcribed.

<u>Answer</u>: 2
The convection currents shown in points 1 and 3 transfer heat from the outer core (number 4) to the lithosphere. Here, the lower density hot magma breaks apart the plates at <em>point 2</em> creating a divergent plate boundary. <u>This new magma mass will drive a lateral movement of the plates</u>. The edges of the plates which have a higher density basalt rock will sink into the mantle and get consumed in trenches/subduction zones
Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes. These chromosomes then become visible. During this stage, the nucleus disappears and the chromosomes appear in the cytoplasm of the cell. ... As metaphase continues, the cells partition into the two daughter cells.
