RNA and DNA are very similar (that is, mRNA is similar, tRNA is quite different). mRNA is basically a single strand of DNA (DNA is a double helix, mRNA is singular), with two differeneces. Firstly, the sugar making up the backbone of the mRNA strand is a ribose sugar, not a deoxyribose sugar (like on DNA). Secondly, the nitrogenous base thymine (which is found on DNA) is replaced witha another base called uracil.
It's also worth noting that mRNA, while manufactured in the nucleus, can leave the nucleus and enter the cell cytoplasm - DNA cannot do this.

∙ 7y agoThe substitution of uracil for thymine as a base material constitutes the chief chemical difference between RNA and DNA. RNA is important in the production of proteins and the process of DNA duplication.

What is made up of three parts a deoxyribose sugar a phosphate group and a nitrogenous base?
nucleotides that are the building blocks of nucleic acids are made up of sugar, a nitrogen base and phosphate group
What are the 5 nitrogen?
The five nitrogenous bases in DNA and RNA are adenine, guanine, thymine, cytosine, and in RNA uracil.
What nitrogen base is found in RNA that pairs with adenine in DNA?
What three things makes up a nucleic tides?
Nucleotides are the components from which nucleic acids (DNA and RNA) are made. Each nucleotide consists of: * a 5 - carbon (pentose) sugar (ribose in RNA, deoxyribose in DNA) * a nitrogen-containing base (adenine, thymine, guanine, cytosine and uracil) * a phosphate group In DNA or RNA the phosphate groups link sugar molecules together to make up a polynucleotide. See http://en.wikipedia.org/wiki/Nucleotide
What are three types of pyrimidines?
Cytosine and thymine are the nitrogenous bases used in DNA. Uracil substitutes for thymine in RNA.
What nitrogenous is found in rna but not in DNA?
A nitrogenous base that is found in RNA but not DNA is uracil.
What nitrogenous base base is found in RNA but not DNA?
Uracil.
Nitrogenous base is found in rNA but not in DNA?
Uracil.
What nitrogenous base is found in DNA but not in RNA is called what?
The nitrogenous base found in DNA but not RNA is called thymine. RNA contains the base uracil which during transcription(when genetic information is copied from DNA to RNA) pairs with the base adenine in DNA. So, DNA has four nitrogenous bases: (A) adenine, (C) cytosine, G (guanine), and T (thymine). And RNA has four nitrogenous bases: (A) adenine, (C) cytosine, G (guanine) and U (uracil)
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 nitrogenous base is not found on DNA but is found on RNA?
Thymine is not found in RNA. It is instead replaced by Uracil.
What is a nitrogen base that is found only in RNA but not DNA?
The nitrogen containing base that is found only in RNA is uracil. It takes the place of thymine in DNA
What is the nitrogenous base that is found only in RNA?
The nitrogen containing base that is found only in RNA is uracil. It takes the place of thymine in DNA
The nitrogenous base adenine is found in all members of which group?
ATP, DNA, and RNA
What nitrogenous base is present in RNA but not DNA?
That would be the base uracil.
What nitrogenous bases are not found is DNA?
Uracil is not found in DNA but in RNA.
What is uracil in RNA?
a base containing nitrogen that is found in RNA (but not in DNA) and derived from pyrimidine; pairs with adenine
