Question

Which of the following are true about the two strands of the double helix? Check all that apply. Phosphodiester bonds hold the two polynucleotide chains together Hydrogen bonds hold the two polynucleotide strands together. The hydrophobic phosphodiester backbone is located in the center of the molecule whereas the hydrophilic nitrogenous bases are on the outside The hydrophobic nitrogenous bases are located in the center of the molecule, whereas the hydrophilic phosphodiester backbone is on the outside. The two strands are parallel. The two strands are antiparallel.

Explanation / Answer

The DNA has two antiparallel strands

1. Hydrogen bonds hold the two polynucleotide strands together.

2. The hydrophobic nitrogenous bases are located in the center of the molecule, whereas the hydrophillic phosphodiester backbone is on the outside.

3. The two strands are antiparallel
