There are 2 main substances that separate RNA from DNA: ribose sugar, and uracil.
All DNA/RNA molecules have a backbone made up of a repeating sequence of sugars and phosphorus. In DNA this sugar is deoxyribose, while in RNA the sugar is ribose. Ribose sugar is different from deoxyribose in that it has an extra oxygen on its second carbon (this is thought to possibly be one of the reasons RNA is less stable than DNA).
The second substance that separates the two is uracil. Attached to the phosphosugar backbone of DNA/RNA are 4 bases. In DNA these are cytosine, guanine, adenine, and thymine (C, G, A and T). However, in RNA the 4 bases are slightly different; they are cytosine, guanine, adenine, and uracil. Uracil is a base that only existsin RNA, while thymine is one that only exists in DNA.
What else can I help you with?
What are the substances represented by the letters A and G called?
The nitrogenous substances A and G are purines (double rings).
Is ribose found in DNA or RNA?
Ribose is found in RNA, not DNA.
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.
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.
Is deoxyribose found in both DNA and RNA?
Yes, deoxyribose is found in DNA, while ribose is found in RNA.
What is the substance in RNA but not DNA?
An uracil base is in RNA but not in DNA
What are the substances represented by the letters A and G called?
The nitrogenous substances A and G are purines (double rings).
Which neuclitides found in RNA not in DNA?
Uracil is a nucleotide found in RNA but not in DNA. In RNA, uracil replaces thymine, which is found in DNA.
What bases found in DNA but not in RNA?
Uracil is found in RNA but not in DNA.
Is ribose found in DNA or RNA?
Ribose is found in RNA, not DNA.
What base is found DNA but not in RNA?
Thymine
What are found in DNA and rna?
Deoxyribose is the sugar found in DNA. Ribose is the sugar found in RNA.
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.
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.
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.
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.
Is deoxyribose found in both DNA and RNA?
Yes, deoxyribose is found in DNA, while ribose is found in RNA.
