What is the difference between the nucleotides of DNA and those of RNA?
Wiki User
∙ 15y ago
A nucleotide is made of 3 parts: Sugar, Phosphate group and Base
RNA and DNA have different sugars and different bases.
1. Sugar
DNA - Deoxyribonucleic acid has the sugar deoxyribose
RNA - Ribonucleic acid has the sugar ribose
In RNA, the sugar has an extra oxygen. In DNA, the oxygen is not there.
2. Bases
DNA has Adenine, Thymine, Guanine, and Cytosine. A pairs with T and C pairs with G.
In RNA, Uracil replaces Thymine. So A pairs with U and C still pairs with G.

∙ 13y agoRNA contains the base uracil while DNA does not.
There are four bases found in DNA strands: adenine, cytosine, guanine, and thymine. The corresponding nucleotides are deoxyadenosinetriphosphate (dATP), deoxycytosinetriphosphate (dCTP), deoxyguanosinetriphosphate (dGTP), and deoxythymidinetriphosphate (dTTP). The di- and mono-phosphate forms are also nucleotides.
In RNA, the thymine base is replaced by uracil, thus RNA contains the bases adenine, cytosine, guanine, and uracil. The corresponding nucleotides are adenosinetriphosphate (ATP), cytosinetriphosphate (CTP), guanosinetriphosphate (GTP), and uridinetriphosphate (UTP). The di- and mono-phosphate forms are also nucleotides.
Note: These are not to be confused with trinucleotides. A trinucleotide is a series of 3 nucleotides in a row, which composes a codon.

∙ 12y agoThe 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 identical whether in RNA or DNA.
The major difference that RNA has from DNA is that RNA uses a ribose sugar backbone while DNA uses deoxyribose. Also, the RNA used for protein synthesis is single stranded, while the parent DNA strand that was transcribed is double stranded.

∙ 11y ago1. RNA is usually single-stranded, and DNA is double-stranded.
2. RNA has ribose, not deoxyribose.
3. RNA has uracil instead of thymine.

∙ 13y agoNucleotides which are DNA related are Adenine, Thymine, Cytosine and Guanine. In RNA the bases are the same exept that Thymine loses an alkyl group and becomes Uracil.

What is the main difference between the four nucleotides that make up DNA is that they have different?
Bases
What is the only difference between the four nucleotides?
All of the four nucleotides have a nitrogenous base. Adenine: has a double ring, nitrogenous base and found in DNA and RNA Thymine:single ring with nitrogenous base. ONLY FOUND IN RNA. not DNA. that is a difference from the rest of the three nucleotides. Cytosine: single ring with nitrogenous base, found in both DNA and RNA Guanine: double ring with nitrogenous base, found in DNA and RNA. also i guess you can say there is another difference with the double and single rings.
What are the differences between the sugar phosphate arrangement in the backbone of the DNA from the plant mammal and the bacterium?
There is no difference between the sugar-phosphate arrangement in the backbone of the DNA from the plant, mammal, and bacterium. What makes plant, mammal, and bacterium different is the sequence of the DNA nucleotides.
Does DNA consists of five different nucleotides and does RNA consists of four different nucleotides?
No, first of in total, both RNA and DNA combined have five nucleotides, DNA and RNA, both consists of three of the same nucleotides, and have one that varies between the two. Both DNA and RNA, have the nucleotides, guanine, cytosine and adenine, however DNA, has the additional nucleotide thymine and RNA instead of thymine has uracil. So, DNA's nucleotides are guanine, cytosine, adenine and thymine, while RNA's are guanine, cytosine, adenine and uracil. To specifically answer the question, no DNA consists of four different nucleotides and RNA consists of three of the same nucleotides, with one differing.
What is the function of DNA polymerase?
DNA polymerases are the enzymes responsible for joining DNA nucleotides together. In Prokaryotes - DNA Pol III is the enzyme which adds nucleotides to the new strand during DNA replication. DNA Pol I is responsible for replacing the primers with DNA nucleotides.
What is the main difference between DNA helicases and DNA molecules?
DNA helicases are proteins, while DNA molecules are nucleotides.
What is the main difference between the four nucleotides that make up DNA is that they have different?
Bases
How can you tell the difference between a DNA molecule undergoing transcription and being replicated?
If the DNA molecule is undergoing transcription, then mRNA nucleotides will be forming along the anti-sense strand of DNA. If the DNA molecule is undergoing replication, new DNA nucleotides will be forming along both original strands of DNA.
Is DNA a single strand of nucleotides?
No, DNA, from difference with the RNA, is a double strand of nucleotides. DNA, double strand (hence the double helix nickname). RNA, single strand.
What is the name of the nucleotides have no DNA and no RNA?
Nucleotides do not have DNA or RNA. DNA and RNA are composed of nucleotides.
What is the only difference between the four nucleotides?
All of the four nucleotides have a nitrogenous base. Adenine: has a double ring, nitrogenous base and found in DNA and RNA Thymine:single ring with nitrogenous base. ONLY FOUND IN RNA. not DNA. that is a difference from the rest of the three nucleotides. Cytosine: single ring with nitrogenous base, found in both DNA and RNA Guanine: double ring with nitrogenous base, found in DNA and RNA. also i guess you can say there is another difference with the double and single rings.
Where does Helicase attach to on the DNA strand?
Enzyme helicase unwinds the DNA by breaking the bonds between nucleotides. Thus attaches itself at the nucleotides.
What type of bond is between nucleotides?
In producing a strand of DNA the nucleotides combine to form phosphodiester bonds.
How can you distinguish a DNA nucleotide from an RNA nucleotide?
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.
What are the differences between the sugar phosphate arrangement in the backbone of the DNA from the plant mammal and the bacterium?
There is no difference between the sugar-phosphate arrangement in the backbone of the DNA from the plant, mammal, and bacterium. What makes plant, mammal, and bacterium different is the sequence of the DNA nucleotides.
The DNA of all living organisms is composed of the same nucleotides It is only the sequence of nucleotides and quantity of DNA an organism possesses that cause the differences between organisms?
True
What is the difference from DNA nucleotide and DNA polymer?
A nucleotide is a single structural unit of DNA. If two or more nucleotides are combined together by a polymerase enzyme, the resulting molecule is a polymer. RNA is also composed of nucleotides and can be formed into polymers.
