protein synthesis

Which two of the following are differences in the structure between RNA and DNA

• DNA uses deoxyribose sugar, RNA uses sugar ribose

• DNA pairs Adenine with Uracil, RNA pairs Adenine with Thymine

• DNA is a single helix, RNA is a double helix

• DNA pairs Adenine with Thymine, RNA pairs Adenine with Uracil

One difference between DNA and RNA is that

• DNA= 1 strand

• DNA contains ribose sugar

• DNA has a double strand

• RNA is more complex
