• Deribonucleic acid
• Diribonucleic acid

Which of the following best describes the shape of a DNA molecule?

• double helix

• single stranded.

• made of amino acids

• an irregular blob.

Which 2 molecules form the sides (backbone) of the DNA ladder?

• deoxyribose sugar and adenine
• deoxyribose sugar and a hydrogen bond
• deoxyribose sugar and the nucleus
• deoxyribose sugar and phosphate

Which nucleotide always pairs with G?
