The microscope in cell studies — practice question

The synthesis of biological molecules involves the formation of bonds. Which row is correct?

  • Aa bond forms between the phosphate of one monomer and the sugar of the next monomer: polynucleotide; a $\beta$-$1,4$ bond forms between the monomers to give an unbranched chain: amylose; the hydroxyl group of the carboxylic acid group is removed and a carbon-nitrogen bond is formed to give an unbranched chain: polypeptide
  • Ba bond forms between the phosphate of one monomer and the sugar of the next monomer: polynucleotide; a $\beta$-$1,4$ bond forms between the monomers to give an unbranched chain: cellulose; the hydroxyl group of the carboxylic acid group is removed and a carbon-nitrogen bond is formed to give an unbranched chain: polypeptide
  • Ca bond forms between the phosphate of one monomer and the sugar of the next monomer: phospholipid; a $\beta$-$1,4$ bond forms between the monomers to give an unbranched chain: amylose; the hydroxyl group of the carboxylic acid group is removed and a carbon-nitrogen bond is formed to give an unbranched chain: polynucleotide
  • Da bond forms between the phosphate of one monomer and the sugar of the next monomer: phospholipid; a $\beta$-$1,4$ bond forms between the monomers to give an unbranched chain: cellulose; the hydroxyl group of the carboxylic acid group is removed and a carbon-nitrogen bond is formed to give an unbranched chain: polynucleotide
