Answer:
The nucleus of a cell contains deoxyribonucleic acid DNA, which is the physical carrier of inheritance.
Step-by-step explanation:
DNA is a double helical structure present in the cells of all living organisms as a basis of the information for the inheritance, growth , maintenance and repair. It is made up of four nitrogen bases known as adenine, thymine, cytosine and guanine. Each of these bases are arranged in an organised manner while they are attached to a sugar moiety and a phosphate backbone to form the complex double helical structure. During the event of a cell division the DNA is copied and is equally distributed into all the daughter cells .
