Motion in Vertical & Horizontal Circle - Physics

Circular Motion:  When a body moves in circle, its motion is called circular motion or angular motion. Circular motion may be divided into two type.
  1. Motion in a horizontal circle.
  2. Motion in a vertical circle.
Motion in Vertical Circle:   In case of vertical circle, acceleration due to gravity plays a role at every point and changes the speed at every point of the motion.

Motion in horizontal Circle:  In this case, acceleration due to gravity does not impart any role in change of speed. However, acceleration acts continuously even when speed is uniform, therefore simple equation of  motion, as used in translation motion, can not be applied.

Genomic Library | Biotechnology

It consists of copy of genetic information of a species in a preferred environment. This library provides easy access to a preferred gene for its further copying or manipulation. In order to establish a genomic library of a particular species. Its DNA is fragmented by means of restriction enzymes and then the fragments are inserted into the plasmids and Bacteriophages which are introduced into bacteria. Such bacteria are cultured at controlled conditions so that they can be used later on.
