DNA vs. RNA Strands
DNA vs. RNA Strands
DNA has two strands, RNA typically has one.
Thymine vs. Uracil
Thymine vs. Uracil
DNA uses thymine (T), while RNA uses uracil (U).

Description
DNA has two strands, RNA does not. A gene is a sequence of nucleotides that controls the production of one type of protein. Sister chromatids attach to each other at the centromere. Ribosomes, proteins, tRNA, DNA gene strands and mRNA are related to protein synthesis.
