Rna differs from Dna by just one oxygen atom. This results in a very slight change in shape that allows more efficient packing.
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.
What else can I help you with?
Is thymine found in both DNA and RNA?
Yes, thymine is found in DNA but not in RNA. In RNA, thymine is replaced by uracil.
Does RNA contain thymine, or is it exclusively found in DNA?
RNA does not contain thymine; thymine is exclusively found in DNA.
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.
Does DNA or RNA contain thymine?
No, RNA does not contain thymine. Thymine is a nitrogenous base found in DNA, but in RNA, thymine is replaced by uracil.
Which base is found on DNA nucleotides but not rna nucleotides?
Thymine is found on DNA nucleotides but not on RNA nucleotides. In RNA, thymine is replaced by uracil.
What base is found DNA but not in RNA?
Thymine
Is thymine found in both DNA and RNA?
Yes, thymine is found in DNA but not in RNA. In RNA, thymine is replaced by uracil.
Which molecules is typically found in DNA but not RNA?
Thymine is found in DNA but not in RNA. Uracil replaces thymine in RNA. In other words: DNA has thymine. RNA has uracil.
Does RNA contain thymine, or is it exclusively found in DNA?
RNA does not contain thymine; thymine is exclusively found in DNA.
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.
Does DNA or RNA contain thymine?
No, RNA does not contain thymine. Thymine is a nitrogenous base found in DNA, but in RNA, thymine is replaced by uracil.
What doesn't have uracil in DNA?
Uracil is not naturally present in DNA. Instead, it is found in RNA, where it replaces the thymine base found in DNA. Thymine is the corresponding base in DNA and is not found in RNA.
Is thymine found in DNA and RNA?
No, in RNA thymine is replaced with uracil.
What is a pyrimidine base found in RNA but not in DNA?
Thymine
Which base is found on DNA nucleotides but not rna nucleotides?
Thymine is found on DNA nucleotides but not on RNA nucleotides. In RNA, thymine is replaced by uracil.
What nitrogen containing base found in DNA but not in RNA?
Thymine is the nitrogen-containing base found in DNA but not in RNA. In RNA, thymine is replaced by uracil.
What base is not present in the nucleotides of RNA?
RNA has the base uracil rather than thymine that is present in DNA, so the answer to you question is.. thymine.
