What does a DNA do ?
A DNA contains the vital instructions needed for an organism to develop , survive and reproduce but before all these functions can be carried out , its sequences must be converted into messages that can be used to produce proteins , which are the complex molecules that do most of the work in our system.

• A sugar ( deoxyribose) : Its name shows that it is a deoxy sugar and it means it is gotten from the sugar ribose by loss of an oxygen atom.
