The only answer I can offer (I must admit that I am not objective and promote the idea I published with my friend some two years ago) is as follows: alfa-ribopyranose (which is in solution in equilibrium with beta-ribopyranose, both furanose forms and an open form) is the easiest racemate to get separated to enantiomers in a process we call the absolute enantioselective separation (AES). It is a chromatography-like process in which the molecules to be separated are oriented in two orthogonal directions parallel to the surface. Then, in opposite enantiomers different groups are oriented towards the surface. Thus, the energy of interactions of opposite enantiomers with the surface is different and in a chromatography-like process the molecules of the opposite enantiomers will move along the surface with different rates. Additionally, AES is capable of separating not only enantiomers but other isomers (including diastereoisomers) as well. The factors that can orient molecules in (more or less) orthogonal directions that are parallel to the surface are:
1. electric field plus an interaction of molecules with a pattern on the (flat) surface or
2. interactions with two independent patterns on the (chiral) surface.
A racemate of ribose is easier to get separated to enantiomers than other mono- saccharides because in one enantiomer all four (including the anomeric one) hydroxy groups are oriented towards the surface while in the opposite enantiomer all these OH groups are oriented against the surface, and thus, the energy of interactions between the enantiomers and the surface is the largest for alfa-DL-ribopyranose. Our answer to the "why ribose" question is that (under specific conditions) it was the only mono- saccharide that could have been isolated in an enantiomerically pure form which is likely to be a necessary condition for the life emergence. [Current Organic Chemistry, 12(12) (2008), 995; Origins of Life and Evolution of Biospheres, 37(2007), 167]. The plausible answer to the question "why is ribose in the beta-furanose form" has been offered by Banfalvi [DNA Cell Biol., 2006, 25, 189].

DNA is deoxyribonucleic acid which is made up of phosphate, deoxyribose sugar and organic nitrogenous bases. It is a totality of both codons and anticodons. it is the source of genetic information. Genetic information refers to the code or specific information carried by a codon (nucleotide) which can be "transcribed" into a messenger RNA to build a specific protein, enzyme or hormone in the body.
An organism's genetic material is packaged in its chromosomes. The genetic material can be in the form of either DNA or RNA.
anything that was once living has genetic material

The deoxyribose sugar in DNA and RNA serves as the backbone of the genetic material, providing structural support for the nucleotide bases. It also plays a crucial role in the stability and integrity of the genetic code, allowing for the storage and transmission of genetic information.
deoxyribose found in DNA and ribose found in RNA.
Deoxyribose is a key component of DNA, the genetic material of living organisms. It helps form the backbone of the DNA molecule, enabling it to store and transmit genetic information. Deoxyribose is essential for processes such as DNA replication and protein synthesis, which are vital for the growth and functioning of living organisms.
The general form of nucleic acid is called deoxyribose nucleic acid or DNA.

The three components of genetic material are deoxyribonucleic acid (DNA), ribonucleic acid (RNA), and proteins. DNA contains the genetic instructions for the development, functioning, growth, and reproduction of all organisms. RNA helps to translate the genetic information from DNA into proteins. Proteins are the functional molecules that carry out various cellular processes based on the genetic information.
The nucleus of a sperm cell contains the genetic material, specifically the haploid set of chromosomes that will combine with the genetic material from an egg during fertilization. This genetic material carries the information needed to create a new organism.

DNA = Deoxyribonucleic acid Deoxyribose is a sugar that differs from another sugar called ribose ("ribo") by missing one oxygen atom ("deoxy"). A nucleic acid is a molecule that stores genetic information.

No, the genome refers to all the genetic material in an organism, including DNA, while DNA specifically refers to the molecule that carries genetic information.
