GENES and DNA

                         Hello friends.....Again we are here to share some interesting topic......Do you want to know what it is......It's absolutely about genes and DNA...

 We all know that cells are the basic unit life....But DNA is the unit of cell...
                         DNA is an amazingly long but slender molecule...It is a helical structure...It is shaped like a twisted ladder. It contains the chemicals as follows..

ADENINE:

GUANINE:

CYTOSINE:

THYMINE:

     

A gene is a segment of DNA with a particular sequence of letters , like a paragraph in a book..The shortest genes are only a few hundred letters long and the longest contains millions.

  Genes and DNA which is packed inside every cell nucleus in your body is a set of instructions that controls the way your body works and develops...........

These instructions known as genes , are stored as a four letter code by the molecule DNA

 AT LAST THE TOPIC COMES TO AN END.....  We hope you understood....Thank you frndzzz
