Ответ:
Friedrich Meischer is responsible for discovering nucleic acids in the blood cells.
Further Explanation:
Nucleic acids refer to the biopolymers which are vital for all the known forms of life. The word nucleic acid is known to be the overall name for the RNA as well as DNA molecule. These are composed of nucleotides that are known to be the monomers consisting of 3 elements; 5 carbon sugar, a phosphate group, and a nitrogenous base.
Nuclein was identified by a Swiss physician as well as a biologist. He was known to be the first scientist to isolate nucleic acid in the year 1869. He was given the task of identifying the composition of the white blood cells or lymphoid cells. These cells were not easy to extract from the lymph glands; however, they were found in high amounts in the pus. He collected the bandages and washed off the pus. He then carried his experiment and isolated a new molecule called nuclein from the cell nucleus. He explained that this molecule is made up of nitrogen, hydrogen, oxygen, and phosphorus.
