Name 2 differences between DNA and RNA. You may set your timer to 1 minute.
Any of the following 2 answers will be accepted: 1) DNA is double stranded while RNA is single stranded. 2) DNA has the nitrogen bases A, T, C, G and RNA has A, U, C, G. 3) DNA has the sugar deoxyribse and RNA has the sugar ribose
