What is the main difference between deoxyribose sugar and ribose sugar?

The key difference between deoxyribose and ribose is that the deoxyribose, the sugar found in DNA, lacks oxygen atom on carbon 2 of the sugar ring while ribose, the sugar found in RNA, has a hydroxyl group on carbon 2 of the sugar ring.

What is the primary difference between ribose sugar and deoxyribose sugar quizlet?

what is the difference between ribose and deoxyribose? Both are sugars the only difference is deoxyribose is lacking oxygen. Can tell the difference by looking at the 2′ carbon. If there is an OH bonded to it is ribose and deoxyribose has just a H.

What is the main difference between ribose and deoxyribose sugar molecules explain with drawing the structure of these molecules?

The ribose and deoxyribose structures are almost the same. Both are simple sugars but deoxyribose has one oxygen atom less in its molecular structure. It plays a major role in the formation of the DNA bases to form the double-helix structure.

What is the difference between deoxyribonucleic acid and ribonucleic acid?

There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.

Why is the sugar of DNA called a deoxyribose?

The carbons in the pentagon are numbered from 1′-4′, starting with the carbon found to the right of the oxygen and moving clockwise. The sugar in DNA is called a deoxyribose because it doesn’t have a hydroxyl group at the 2′ position.

Why is ribose sugar less stable than deoxyribose?

While DNA contains deoxyribose, RNA contains ribose, characterised by the presence of the 2′-hydroxyl group on the pentose ring (Figure 5). This hydroxyl group make RNA less stable than DNA because it is more susceptible to hydrolysis.

Why is deoxyribose sugar more stable than ribose?

Due to its deoxyribose sugar, which contains one less oxygen-containing hydroxyl group, DNA is a more stable molecule than RNA, which is useful for a molecule which has the task of keeping genetic information safe. RNA, containing a ribose sugar, is more reactive than DNA and is not stable in alkaline conditions.

What is sugar in DNA called?

Sugar. Both DNA and RNA are built with a sugar backbone, but whereas the sugar in DNA is called deoxyribose (left in image), the sugar in RNA is called simply ribose (right in image).
