Yes. Adenine and guanine compose the nucleotide group known as purines. These are two ring structures and thus, the molecules are larger. Cytosine and thymine are pyrmadines and are only composed of one ring.
If those are elements, then take a look at the amount of valence electrons they have. However, I'm thinking that those are compounds. If the compounds are stable, then they can't join together simply because the elements within the compounds have organized their valence electrons so that there is no longer a requirement for them. I don't know what these compounds are, but if I had to guess, it would be because they are both stable.
It depends on the context. In a biological context, pyrimidines are the nucleotides with a single ring in the nitrogenous base. These include thymine and cytosine in DNA and uracil and cytosine in RNA. In an organic chemistry context, the answer is longer.
pre mRNA contains the same things as mRNA - phosphates -uracil, adenine, guanine, cytosine -ribose sugar -hydrogen bonds -covalent bonds -GTP cap -Poly A tail However, pre mRNA is different because it still contains introns and exons, while mRNA only contains exons introns code for things which are no longer expressed as traits, and therefore are not translated, they are instead removed by splicesomes exons code for the traits expressed and therefore are not removed and are expressed
DNA makes up our genetic code, containing instructions for the development, functioning, growth, and reproduction of all living organisms. It exists within the nucleus of cells and is composed of a double helix structure made up of nucleotide base pairs.
The latter is longer.
In RNA, the nitrogenous bases change and there is no longer Thymine, instead Uracil replaces Thymine but it bonds with the same base pair ( Adenine) as it would in DNA. In other words DNA base pairs are : Adenine- Thymine, Guanine-Cytosine. RNA base pairs are : Adenine- Uracil, Guanine-Cytosine.

DNA's rungs are made from a purine that is longer and always Guanine (G) or Adenine (A) and a pyrmidine which is small and always Cytosine (C) or Thymine (T). So each DNA rung is always equal with a base pair of ( A ) and ( T ) or ( G ) and ( C ).
Like DNA, RNA contains the bases adenine (A), cytosine (C), and guanine (G); however, RNA does notcontain thymine, instead, RNA's fourth nucleotide is the base uracil (U). Unlike the double-stranded DNAmolecule, RNA is a single-stranded molecule.
Adenine (A) and Guanine (G) are the nitrogen bases that are slightly longer.
DNA is made from nucleic acids, which are long chains of nucleotides. Each nucleotide contains a sugar (deoxyribose), a phosphate group, and a nitrogenous base (adenine, thymine, cytosine, or guanine).
DNA is a very large molecule, made up of smaller units called nucleotides that are strung together in a row, making a DNA molecule thousands of times longer than it is wide. Each nucleotide has three parts: a sugar molecule, a phosphate molecule, and a structure called a nitrogenous base. The nitrogenous base is the part of the nucleotide that carries genetic information, so the words "nucleotide" and "base" are often used interchangeably. The bases found in DNA come in four varieties: adenine, cytosine, guanine, and thymine

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)

DNA is double stranded while rna is single stranded. DNA contains the bases a, g, t, c while RNA contains the bases a, g, c, u. See Protein Synthesis. they are also different because they have different meaning DNA is deoxyribonucleic acid and RNA is ribonucleic acid.
Adenine is the v4 it is produced by the body, no longer considered a vitamin and it is not part of the list. At one time it was, and the scientists discovered it is part of the metabolism of humans.
