Answer 2

The nucleic acid was discovered by a scientist named Friedrich Miescher. So the correct option is 'D'.

Explanation:

• Nucleic acids are of two types- DNA or RNA. Nucleic acids are made up of small units known as nucleotides.
• Mieshcher was a Swiss physician who isolated some 'novel' compound from the nuclei of white blood cells. He termed it as 'nuclein'.
• Upon studying the constitution he discovered that it was neither a lipid, nor carbohydrate or protein. Later nuclein was termed as DNA.
• Watson and Crick proposed the double- helical model of the DNA.
• Wilkins was the one who studied DNA through X- ray diffraction.
