Kritika Trehan 8 years, 4 months ago

The largest cell in the human body is the female egg, also known as ovum; it's 1000 micrometres in diameter. The smallest cell in terms of volume is the sperm cell—it's little more than a nucleus propelled by mitochondria and a flagellum.

To visualise dna fragments

Kritika Trehan 8 years, 4 months ago

Typically, a DNA molecule is digested with restriction enzymes, and the agarose gel electrophoresis isused as a diagnostic tool to visualize the fragments. An electric current is used to move the DNA molecules across an agarose gel, which is a polysaccharide matrix that functions as a sort of sieve. 

The matrix helps "catch" the molecules as they are transported by the electric current.

Electricity is used to move DNA molecule fragments through the agarose gel.

This technique has lots of applications. Generally speaking you can analyze DNA fragments that result from an enzyme digestion of a larger piece of DNA to visualize the fragments and determine the sizes of the fragments.

In addition to its usefulness in research techniques, agarose gel electrophoresis is a common forensic technique and is used in DNA fingerprinting.

Withdrawal is less effective than most other contraceptive methods. As commonly used, it is only 78 percent effective, meaning that 22 of every 100 women whose partners use withdrawal will become pregnant over a year.
