Explanation:
Genes are contained in chromosomes, which are in the cell nucleus. A chromosome contains hundreds to thousands of genes. Every normal human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes. Some traits are caused by mutated genes that are inherited or that are the result of a new gene mutation.
The genetic code is carried out by the Deoxyribonucleus acid DNA molecule in most organisms. Most of the viruses have RNA as their genetic material which codes genetic information.
