Answer:

Deoxyribose sugar and phosphate groups

Explanation:

The Deoxyribose and phosphate groups are held together by hydrogen bonds. The Deoxyribose is also connected to the nucleic acids, making a complete nucleotide. Deoxyribose is only used in DNA, because DNA means Deoxyribonucleic Acid. RNA is made with a sugar called Ribose.

The two molecules that forms the backbone of DNA ladder are:

1. Deoxyribose

2. Phosphate groups

  • Deoxyribose is a pentose sugar important in the formation of DNA, or deoxyribonucleic acid.
  • Deoxyribose is a key building block of DNA. Its chemical structure allows for the replication of cells in DNA's double helix configuration.
  • A phosphate backbone is the portion of the DNA double helix that provides structural support to the molecule.
