1.	Give Reason :Initially proteins (and not DNA) were considered as genetic material.
Answer» 1. Proteins are large, complex molecules and store information required to govern cell metabolism. Hence it was assumed that variations found in species were caused by proteins. 2. On the other hand, DNA was considered as a small, simple molecule whose composition does not vary much among species. 3. Variations in the DNA molecules are different than the variation in shape, electrical charge and function shown by proteins. 4. Hence, initially proteins (and not DNA) were considered as genetic material.
