What 4 base appear on RNA but not on DNA?
The four bases that appear in RNA but not in DNA are adenine (A), cytosine (C), guanine (G), and uracil (U). In RNA, uracil replaces thymine, which is found in DNA. While both RNA and DNA share adenine, cytosine, and guanine, the presence of uracil is a key distinction of RNA.
What base is found in DNA?
In DNA the 4 nitrogenous bases are Adenine, Guanine, Thymine, and Cytosine. In RNA Thymine is replaced by Uracil.
What substances would not be found in RNA?
To understand what substances do not exist in RNA, it is important to first understand what substances ARE in RNA. RNA, like DNA, is a polymer. It is made up of many repeating units of molecules, over and over again. RNA is a phosphosugar, meaning that it is primarily made up of molecules of phosphorus and sugars over and over again. In the case of RNA, the sugar in question is the "ribose" sugar. Ribose sugar in RNA is almost indistinguishable from its DNA counter part "deoxyribose" sugar. What separates ribose from deoxyribose, is the presence of an oxygen molecule on the sugar's second carbon, which deoxyribose lacks. The phosphorus and the ribose alternate repeatedly, over and over to form the backbone of the RNA molecule. In addition to the backbone of RNA, 4 nitrogenous bases are attached to each of the ribose sugars on the backbone. These 4 bases are adenine, cytosine, guanine, and uracil. Particular importance is placed on the presence of uracil in RNA, because uracil also happens to be absent in DNA. Instead, DNA molecules use the base thymine. This too is a distinguishing factor between DNA and RNA. In knowing this we can make the following important deductions as to what substances are NOT found in RNA: 1. Deoxyribose sugar is not found in RNA (only DNA) 2.Thymine is not found in RNA (only in DNA) 3. Essentially any substance that is not ribose sugar, phosphorus, or any of the RNA bases (A,G,C, and U), is not found traditionally, in RNA.
What are three major differences between the structures of DNA and RNA?
RNA and DNA differ in these ways: (1) DNA has deoxyribose sugar, and RNA has ribose sugar. (2) DNA is made up of these four bases: adenine & guanine, cytosine & thymine; RNA is made up of adenine & guanine, cytosine & URACIL, the difference being that in RNA, uracil replaces thymine. (3) DNA is a double stranded molecule, and RNA is a single stranded molecule. (And for an optional 4)RNA can travel in and out of the nucleas of the cell. The DNA is stuck in the nucleas.
What nitrogenous base is present in RNA but not DNA?
That would be the base uracil.

What are the names of the 4 letters in the cell?
If you are referring to the four nitrogen bases found in DNA and RNA, they are as follows: DNA - adenine, guanine, cytosine, thymine; RNA - adenine, guanine, cytosine, uracil.

What substance is found in RNA but not in DNA?
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.
Does dna and RNA have nitrogenous bases?
Both DNA and RNA have nitrogenous bases. The nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G). The nitrogenous bases in RNA are adenine (A), uracil (U), cytosine (C), and guanine (G). In DNA, A and T pair together, as does C and G. In RNA, C and G also pair together, but A pairs with U because U replaces T in RNA.
What are the types of nucleic acids?
RNA and DNA
How is DNA different from RNA?
1. DNA has Thymine as one of its nitrogenous bases while RNA has Uracil instead of Thymine.2. RNA includes a ribose sugar, while DNA includes a deoxyribose.3. In terms of their physical structure, DNA is a double helix, while RNA is a single strand.4. DNA is found only inside of the nucleus because it is too big to pass through the nuclear pores. RNA passes through the nuclear envelope from the nucleus to the cytoplasm.5. DNA stands for DeoxyriboNucleic Acid while RNA is RiboNucleic Acid.DNA is the data being stored within the nucleus, RNA is a messenger protein string that is used to create new parts of a cell, since the original DNA copy cannot be moved
Difference from DNA and RNA?
1. DNA is composed of a deoxyribose sugar and a phosphate backbone where as RNA is composed of ribose sugar and the phosphate backbone. 2. DNA uses Purines Adenine and Guanine and the Pyrimidines Cytosine and Thymine RNA uses the Purines Adenine and Guanine and the Pyrimidines Cytosine and Uracil, Uracil being the only difference between them here. 3. DNA takes the form of an anti-parallel double stranded helix whereas RNA has many more structural possibilities. These include single-strand (mRNA) or secondary structures (tRNA and other enzymatic RNA). 4. DNA cannot leave the nucleus and therefore needs RNA to transcribe it for its genetic information to be of use. 6. Ribose sugar on the RNA backbone makes it more reactive. RNA can serve as primitive enzymes. 7. There are many types of RNA defined based on function and structure. There include mRNA, tRNA, rRNA, snRNA, snoRNA, etc. Because of RNA's differences it can perform many other functions and take on many more unique shapes than DNA which is essential to tasks such as DNA and protein synthesis and can even combine with enzymes to perform far more tasks.
3 differences between RNA and DNA?
DNA has a deoxyribose sugar; RNA has ribose sugar. DNA is double stranded; RNA is single. DNA has adenine that pairs with thymine, guanine that pairs with cytosine; RNA has adenine that pairs with uracil, guanine that pairs with cytosine. DNA resides in the nucleus; RNA resides in both the nucleus and the cytoplasm (near ribosomes)
