- thymine has a methyl group which is not found in uracil. Having a methyl group means it is more stable. That is why thymine is more stable that uracil. DNA is more stable than RNA because DNA has deoxyribose sugar and RNA has ribose sugar. So DNA has thymine base and RNA has uracil. Also, all genetic info is stored in DNA, so DNA has to be stable and 'long-lived' to stored the information.

Why is uracil found only in RNA? Nucleotides are composed of three units: base, sugar (monosaccharide) and phosphate. Bases are found in both DNA and RNA. As seen below, they are adenine, cytosine, guanine, thymine, and uracil.They are abbreviated (A, C, G, T, U).denine (A) cytosine (C) guanine (G) thymine (T) uracil (U). The sugar component in RNA is ribose and in DNA is deoxyribose (hence the name ribonucleic acid and deoxyribonucleic acid). The third component of nucleotides is the phosphate ion.

- The substitution of Uracil in Rna [instead of … Thymine] has the same effect-improved spacing; it most likely provides a 'unique identification' function as well, all those Dna and Rna polymerases need to have some way to direct them to their appropriate Job Sites.

Why does RNA have uracil and DNA has thymine? Best Answer: I think it's because DNA needs thymine to replicate and produce daughter strands, and also protects the DNA from attack and manipulation. However RNA does not need this as it is not a part of a genomic building block ie/ all organisms are made up of DNA, so it uses uracil.

Difference Between DNA and mRNA DNA has thymine as one of the two pyrimidines while mRNA has uracil as its pyrimidines base. DNA is present in the nucleus while mRNA diffuses into the cytoplasm after synthesis. DNA is double-stranded while mRNA is single-stranded. mRNA is short-lived while DNA has a long lifespan.

An Introduction to Molecular Biology/DNA the unit of life In DNA, the purine bases are adenine and guanine, while the pyrimidines are thymine and cytosine. RNA uses uracil in place of thymine. Adenine always pairs with thymine by 2 hydrogen bonds, while guanine pairs with cytosine through 3 hydrogen bonds, in each case because of the unique structures of the bases.

Why does RNA have uracil and DNA has thymine? RNA or DNA nucleotides containing either thymine or uracil are all complementary to DNA or RNA nucleotides containing Adenine. It is therefore all to do with probability of occurence of the more stable form, and of inclusion in the polynucleotide that is subsequently created. duncrhodes · 10 years ago.

The Differences Between DNA and RNA 1 DNA and RNA base pairing is slightly different, since DNA uses the bases adenine, thymine, cytosine, and guanine; RNA uses adenine, uracil, cytosine, and guanine. 2  Uracil differs from thymine in that it lacks a methyl group on its ring.

DNA has deoxyribose sugar while RNA has ribose sugar. The deoxyribose sugar has one less oxygen atom than the ribose sugar. DNA is longer than RNA because DNA contains all the genes of the organism and more besides.

Difference Between Purine and Pyrimidine Cytosine, thymine, and uracil are examples for pyrimidine bases. Adenine and guanine are the two purine bases. DNA has adenine, Guanine, cytosine, and thymine bases, whereas RNA has A, G, C, and uracil (instead of thymine). In DNA and RNA, complimentary bases form hydrogen bonds between them.That is adenine: thiamine/ uracil and guanine: cytosine are complimentary to each other. Pyrimidine has one ring and purine has two rings. • Purine has a pyrimidine ring and an imidazole ring. • Adenine and guanine are the purine derivative present in nucleic acids whereas cytosine, uracil and thymine are the pyrimidine derivatives present in the nucleic acids.

Why is uracil found only in RNA? RNA is a polymer with a ribose and phosphate backbone and four different bases: adenine, guanine, cytosine, and uracil. The first three are the same as those found in DNA, but in RNA thymine is replaced by uracil as the base complementary to adenine. This base is also a pyrimidine and is very similar to thymine.

- First, thymine is a methylated analogue of uracil, DNA can be protected from nuclei by methylation. Second, uracil has more base pair affinity to adenine, but it can also pair up with other bases including itself. This can lead to mutations in our genetic material.

Pyrimidine Thus, in DNA, the purines adenine (A) and guanine (G) pair up with the pyrimidines thymine (T) and cytosine (C), respectively. In RNA, the complement of adenine (A) is uracil (U) instead of thymine (T), so the pairs that form are adenine: uracil and guanine: cytosine.he pyrimidine ring system has wide occurrence in nature as substituted and ring fused compounds and derivatives, including the nucleotides, thiamine (vitaminB1) and alloxan.

DNA RNA Protein Flashcards Three bases are identical in both DNA and RNA: adenine (A), cytosine (C), and guanine (G). The fourth base in RNA is uracil (U); in DNA it is thymine (T). The difference between these two is small: U lacks a methyl group. A and G are purines; C, T, and U are pyrimidines, which are smaller.

Structural Biochemistry/Nucleic Acid/Nitrogenous Bases/Pyrimidines/Uracil Uracil is among the five nucleobases: adenine, guanine, cytosine, and thymine,but is only found in RNA. It is a naturally occurring pyrimidine derivative with the molecular formula C4H4N2O2. Uracil is planar and unsaturated and has the ability to absorb light.

Structure of Nucleic Acids The uracil base replaces thymine in RNA. Thymine and uracil are structurally very similar. Uracil has fundamentally the same structure as thymine, with the deletion of a methyl group at the 5' position. Uracil will base pair with adenine in the same way as thymine pairs with adenine ().
