Answer 1

The DNA is the information source for making protein in the cell.A section of DNA that provides information for one protein is called the Gene for that protein. Genes are segments of DNA that are carried on the chromosomes and determine specific traits. Proteins control the traits.
*Genes* are passed from one generation to the next. Genes hold the instructions for making protein products (like enzymes). As the cells duplicate,they pass this genetic information to new cells.**BUT*genes do not carry out the actual work. Rather, they serve as instructions for making functional molecules such as RNA and proteins,which perform the chemical reactions in the body. It is *THESE PROTEINS* which carry out the actual function of performing different functions and controlling various characteristics.SO GENES PRODUCE THE PROTEINS WHICH IN TURN CONTROL THE TRAITS. Hope it helps.
