The DNA molecule consists of paired nucleotides that make each "rung" of the ladder. Each nucleotide is made up of a one of four nitrogenous bases (adenine, guanine, cytosine, or thymine), a five-carbon sugar (either ribose or 2'-deoxyribose), and a phosphate molecule.

Importance is the deoxyribose molecule in the structure of DNA?

Deoxyribose is a key component of the DNA molecule as it forms the "backbone" of the DNA strand. It provides stability and structure to the DNA molecule by linking the individual nucleotides together. Without deoxyribose, DNA could not exist in its double helix structure and carry out its functions in storing genetic information.


What is the role of deoxyribose in DNA structure and function?

Deoxyribose is a sugar molecule that forms the backbone of DNA. It helps to stabilize the structure of the DNA molecule and plays a crucial role in storing and transmitting genetic information.
