Introduction. DNA is the molecule which controls the synthesis of proteins. Proteins are used for growth and repair and also as enzymes, in which form they catalyse all other cellular activities. Thus DNA is able to exert a controlling influence over the whole cell and ultimately, the whole organism.The segments of DNA which hold the key to this control are the genes.roteins are used for growth and repair and also as enzymes, in which form they catalyse all other cellular activities.

The nucleus, often thought as as the centre of a cell, contains all the genetic. information of a cell (the cells chromosomes), it controls the activities of the cell. Cytoplasm surrounds the nucleus within the cell walls. It is where reactions take place in the cell.The cell membrane controls the movement of chemicals in and out of the cell. The cell wall, which is made up of cellulose, strengthens the cell.Chloroplast contain chlorophyll, and are used in photosynthesis.t is where reactions take place in the cell.
