-The nervous system consists of two main parts: the central nervous system and the peripheral nervous system: The central nervous system is made up of the brain and spinal cord.

-The central nervous system controls most functions of the body and mind.It controls all parts of the body. It receives and interprets messages from all parts of the body and sends out instructions. The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement.

-The spinal cord serves as a conduit for signals between the brain and the rest of the body and also controls simple musculoskeletal reflexes without input from the brain.

    2. Organisms store and transmit genetic information

    3. Cells contain protein molecules.

Explanation:

The study of DNA started much before the discoveries of Rosalind Franklin and Maurice Wilkins.

Proteins as a constituent of cell were discovered by the experimental analysis of Gerhardus Johannes Mulder in 1837.

DNA as a genetic material came from the experimental studies of Frederick Griffith in 1928, Oswald Avery, Maclyn McCarty, and Colin MacLeod in 1944, and Hershey and Chase in 1952.

Franklin and Maurice Wilkins are known for their work on the the structure of DNA as they were able to produce high-resolution X-ray photographs of DNA fibres called Photo 51 in 1952 using X-ray diffraction technique. By 1953 Franklin concluded concluded that DNA shows helical structure with phosphates on outer side.

Thus, 1. DNA is found in the nucleus of a cell

         2. Organisms store and transmit genetic information

         3. Cells contain protein molecules.

             are the correct options.
