Assertion : Restriction enzymes cut the strand of DNA to produce sticky ends. Reason: Stickiness of the ends facilitates the action of the enzyme DNA polymerase.

Step-by-step solution

Restriction enzyme, a type of endonuclease, functions by "inspecting" the length of a DNA sequence. Once it finds a recognition sequence, it binds and cut each of the two strands of the double helix at specific point leaving single stranded portions at the ends. This results in overhanging stretches called sticky ends. These in the same individual. These are called bisexual or monoecious animals or hermaphrodites. In these animals, testes and ovaries do not mature simultaneously. For example in earthworm, testes ma
