Riaan S.
Which of the following is not a difference between DNA and RNA? a. DNA contains thymine whereas RNA contains uracil b. DNA contains deoxyribose and RNA contains ribose c. DNA contains alternating sugar-phosphate molecules whereas RNA does not contain sugars d. RNA is single stranded and DNA is double stranded
Which statement best explains the chemical differences between DNA and RNA? (a) DNA has two different sugars in its sugar-phosphate backbone, but RNA only has one. (b) Thymine is one of the DNA bases, whereas RNA's corresponding base is thymine minus a methyl group. (c) The RNA sugar-phosphate backbone contains fewer oxygen atoms than DNA's backbone. (d) DNA forms double helices but RNA cannot.
