The presence of an oxygen atom in ribose's 2' carbon makes it more reactive than deoxyribose, which lacks this oxygen atom.

What 5 carbon sugar that makes up RNA and DNA?

In DNA the five-carbon sugar is deoxyribose. In RNA the five-carbon sugar is ribose.


What type of sugar makes up the backbone of the DNA molecule?

The sugar found in the backbone of DNA is the deoxyribose.


What sugar does RNA have that is different from the sugar in DNA?

The sugar in RNA is ribose, whereas the sugar in DNA is deoxyribose. The only difference between the two is that in deoxyribose, there is an oxygen missing from the 2' carbon (there is a H there instead of an OH). This makes DNA more stable/less reactive than RNA.


Why does DNA have deoxyribose sugar?

There are two answers: Ribose makes sugar phosphate backbone reactive. Thus, branching could occur since both the 2 prime and 3 prime positions can be involved in phosphodiester bonds. Deoxyribose makes DNA much more stable at high pH, RNA is alkaline (unstable).


What is sugar in DNA?

Sugar in DNA refers to deoxyribose, a type of sugar molecule that is a structural component of DNA. Deoxyribose is a 5-carbon sugar that makes up the backbone of the DNA molecule, linking the nucleotide bases together.


What parts of a nucleotide makes up the back bone of the nucleic acids?

The sugar-phoshate part is what makes up the backbone, ribose in RNA and 2-Deoxyribose in DNA with a single phosphate group per nucleotide.


Why is deoxyribose instead of ribose found in DNA?

The only difference between deoxyribose and ribose is that the Oxygen from the 2' carbon is not there in the deoxyribose - 'deoxy' meaning less oxygen. This makes DNA much more stable than RNA, as RNA is easily destabilised at basic pH.


What is deoxyribose?

Deoxyribose, also known as D-Deoxyribose and 2-deoxyribose, is an aldopentose - a monosaccharide containing five carbon atoms, and including an aldehyde functional group in its linear structure. Deoxyribose is a constituent of the nucleotide bases that form DNA.


What is the name of the sugar that makes up DNA?

DNA is made up of deoxyribose, a sugar. Add ons, like nitrogen and phosphate leave us with the four basic building blocks of DNA Adenine, Guanine, Cytosine and Thymine. DNA stands for deoxy-ribo-nucleic-acid


Name the 3-part structure that makes up both DNA and RNA?

The 3-part structure that makes up DNA and RNA is composed of a sugar molecule (deoxyribose in DNA and ribose in RNA), a phosphate group, and a nitrogenous base (adenine, cytosine, guanine, thymine in DNA and uracil in RNA). These components form the backbone of the nucleic acid molecules.


What are the three molecules of a nucleotide?

The three molecules of a nucleotide are a phosphate group, a five-carbon sugar (ribose or deoxyribose), and a nitrogenous base (adenine, cytosine, guanine, thymine, or uracil). These components form the basic building blocks of nucleic acids like DNA and RNA.


What parts of a nucleotide make up the back bone of a nucleic acid?

The sugar-phoshate part is what makes up the backbone, ribose in RNA and 2-Deoxyribose in DNA with a single phosphate group per nucleotide.
