RNA is a vital molecule found in your cells, and it is necessary for life. Pieces of RNA are used to construct proteins inside of your body so that new cell growth may take place.
Q. Is ribose in DNA or RNA?
Unlike DNA, RNA in biological cells is predominantly a single-stranded molecule. While DNA contains deoxyribose, RNA contains ribose, characterised by the presence of the 2′-hydroxyl group on the pentose ring (Figure 5).

Q. Does backbone of RNA contain ribose?
DNA stands for “deoxyribonucleic acid.” The backbone of DNA is comprised of alternating sugar and phosphate units, in which the sugar is deoxyribose. The backbone of RNA is also comprised of sugar and phosphate units, but uses the sugar ribose.
Q. Why does RNA use ribose?
Adjacent ribose nucleotide bases are chemically attached to one another in a chain via chemical bonds called phosphodiester bonds. Unlike DNA, RNA is usually single-stranded. Additionally, RNA contains ribose sugars rather than deoxyribose sugars, which makes RNA more unstable and more prone to degradation.
Q. What are the 3 major differences between DNA and RNA?
So, the three main structural differences between RNA and DNA are as follows:
- RNA is single-stranded while DNA is double-stranded.
- RNA contains uracil while DNA contains thymine.
- RNA has the sugar ribose while DNA has the sugar deoxyribose.
Q. What does the R stand for in RNA?
ribosomal
Q. What is the R in rRNA?
Ribosomal RNA, or rRNA, is a structural component of ribosomes. Ribosomes are made of several dozen proteins, as well as rRNA. Transfer RNA, or tRNA, is involved directly in the protein making process. It is a small, clover-shaped molecule that carries an amino acid on top.
