We know that if an object is lying at a distance more than the focal length of a convex lens,its real and inverted image is formed on the other side of lens.The image through the eye and camera is formed in the same way.Let us compare the structure and function of both of them.
CAMERA. camera is a kind of box to which q convex lens is mounted on the front side.The lens form a real and inverted image of an object on a sensitive image film placed behind it.A system is provided in a camera to move the lens back and forth...

Genetic Testing genetic testing is one of the latest biotechnologocal techniques used for genetic diagnosis of inherited diseas.It involves the direct examination of DNA molecule.Itbis also used to determine a child's paternity or a persos ancestry.
Coloning. coloning is also amongst the latest biotechnology...
GENETIC MODIFICATIONS AND BIOTECHNOLOGY PRODUCTS
The change in the genes of organisms using biotechnology techniques is called genetic .The change in the genes of organism can be produced by removal,addition or modification of genes.It is the modern method to change the character of organism.FOR EXAMPLE,this process is used in crops to develope resistance in plants against disease causing microorganisms.The organism whose genes are modified is called GENETICALLY MODIFICATION ORGANISM...
