DNA vs RNA

Basis of Difference	DNA	RNA
Location	Present in nucleus.	Present in nucleus and cytoplasm.
Sugar	Deoxyribose	Ribose
Bases	A T G C	A U G C
Functions	Contains the genetic instructions used in the development and functioning of all known living organisms .	involved in protein synthesis and sometimes in the transmission of genetic information.
Strands	Double- stranded molecule	Single-stranded molecule
Unique Feature	The helix geometry of DNA is of B-Form. DNA is completely protected by the body i.e. the body destroys enzymes that cleave DNA. DNA can be damaged by exposure to Ultraviolet rays .	The helix geometry of RNA is of A-Form. RNA strands are continually made, broken down and reused. RNA is more resistant to damage by Ultra-violet rays.
Complementary base pairing	A-T(Adenine-Thymine), GC(Guanine-Cytosine)	A-U(Adenine-Uracil), GC(Guanine-Cytosine)

DNA - Other Features : 

1. DNA does not usually exist as a single molecule, but instead as a tightly-associated pair of molecules. 
2. These two long strands entwine like vines, in the shape of a double helix. 
3. This arrangement of DNA strands is called antiparallel. 
4. The asymmetric ends of DNA strands are referred to as the 5′ (five prime) and 3′ (three prime) ends. 

DNA Double Helix

RNA - Other Feature : 

RNA usually exists in two ways -
(i) Single Stranded
(ii) Hairpin loop - Double Stranded.
