5 True/False questions

  1. double helixThe form of native DNA, referring to its two adjacent polynucleotide strands wound into a spiral shape


  2. condensation reactionA chemical reaction in which two molecules covalently bond to each other with the removal of a water molecule


  3. polysaccharideThe simplest carbohydrate, active alone or serving as a monomer for disaccharides and polysaccharides. Also known as simple sugars, the molecular formulas of monosaccharides are generally some multiple of CH20


  4. polypeptideA polymer (chain) of many amino acids linked together by peptide bonds


  5. carbohydrateA sugar (monosaccharide) or one of its dimers (disaccharides) or polymers (polysaccharides).
