DNA = a double helix
RNA = single stranded
A double helix is a structure that has two sides and is twisted like a spiral staircase. It is the shape of DNA. DNA's sides are made of sugar (deoxyribose- hence the "D" in its name) and phosphate. While the interior is made of nucleic base pairs: adenine, thymine, cytosine, and guanine.
2. Nucleic Acids
The interior nucleic bases ares: adenine (A), thymine (T), cytosine (C), guanine (G) and uracil (U).
DNA contains A, T, C, and G. In DNA, A pairs with T and G pairs with C.
RNA contains A, U, C, and G. In RNA, A pairs with U and G remains with C.
DNA is more stable
RNA is less stable
I hope this helps! :)
