WHAT IS GENE? |
Genes are the working subunits of DNA. Each gene contains a particular set of instructions, usually coding for a particular protein or for a particular function.The DNA in each chromosome constitutes many genes. The DNA also contains large sequences that do not code for any protein and their function is not known. The gene of the coding region encodes instructions that allow a cell to produce a specific protein or enzyme. There are nearly 50,000 and 100,000 genes with each being made up of hundreds of thousands of chemical bases. |
