<span>DNA stands for deoxyribonucleic
acid. It has a double strand that contains the genes (a hereditary material) of
the organism. It was discovered by James Watson and Francis Crick. Their double-helix
structure was based on x-ray diffraction image named as Photograph 51 or Photo
51. It was taken by Raymond Gosling, a pHD student under the supervision of
Rosalind Franklin. They used this photo to determine the chemical and physical
structure of the DNA and the bond that links the genes altogether. The answer is Rosalind Franklin</span>
Answer: they are mostly single celled organisms and they usually reproduce A-sexually.
Guanine and adenine, structure-wise, are purines.
Answer:
The density of the object is 2 g/cm³.
Explanation:
Density = Mass/Volume
