Explanation

Most `DNA` of higher organisms, both plant and animal, is found in the nucleus of cells in the form of threadlike strands that in the nucleus of cells in the forms of threadlike strands that are coated with protein and wound into complex assemblies called chormosomes.
Each chormosome is made up of several thousand genes, where a gene is a segment of a `DNA` chain that contains the instruction necessary to make a specific protein. By decoding the right genes at the right time, an organism use genetic information to synthesize the thousands of proteins needed for living.
