DNA :1. It usually occurs insidenucleusan d some cell organelles (Mitochondria andChloroplast in plants2. It isdouble strandedwith exception of some viruses3. DNA contains over a million nucleotides.

RNA:1. Very little RNA occurs inside the nucleus. Most of it is found in thecytoplasm.2. It issingle strandedwith exception of some viruses 3. Depending on the type, RNA contains 70-12,000 nucleotides.
