How can you distinguish a DNA nucleotide from an RNA nucleotide?

In: Biology, Microbiology, Genetics [Edit categories]

Answer:

The key difference between a DNA nucleotide and an RNA nucleotide is their five-carbon sugar molecules.

One component of RNA is the five-carbon sugar ribose, C₅H₁₀O₅. Alternatively, in DNA, the five-carbon sugar deoxyribose (C₅H₁₀O₄) has one fewer oxygen atom.

Another difference is in the nitrogenous bases of some DNA and RNA nucleotides. The nitrogenous base uracil (U) is unique to RNA nucleotides. Similarly, the nitrogenous base thymine (T) is unique to DNA nucleotides.

Relevant answers:

How is RNA nucleotide and DNA nucleotide alike?
DNA nucleotide has deoxyribose sugar (mean 5 carbon rings sugar which we took one hydrogen atom from the ring) and RNA nucleotide has ribose sugar(mean 5 carbon sugar).
How is an RNA nucleotide different from an DNA nucleotide?
The individual nucleotide is no different, except RNA utilizes Uracil instead of Thymine, as well as other minor nucleotides. The chemical structures of Adenine, Cytosine, and Guanine are all...
What nucleotide is found in RNA but not in DNA?
Uracil. It is the Rna replacement for Thymine in DNA.
Do DNA and RNA have the same nucleotides?
Yes, except uracil substitutes for thymine in RNA.
Parts of nucleotides of RNA and DNA?
for DNA it is Nitrogenous base, deoxyribose sugar, and phosphate group.for RND it is Nitrogenous base, ribose sugar, and phosphate group.
