There are four DNA bases: adenine, guanine, thymine, and cytosine. Another base, uracil, is only seen in RNAs. Remdesivirʹs1pyrrolotriazine fragment bears a striking resemblance to adenine and guanine. Therefore, pyrrolotriazine can serve as a bioisostere of those two bases required for the...
The base pairs in DNA are adenine with thymine and cytosine with guanine. Hydrogen Bond A hydrogen bond is a weak chemical bond that occurs between hydrogen atoms and more electronegative atoms, like oxygen, nitrogen and fluorine. The participating atoms can be located on the same molecule (...
like oxygen, nitrogen and fluorine. The participating atoms can be located on the same molecule (adjacent nucleotides) or on different molecules (adjacent nucleotides on different DNA strands). Hydrogen bonds do not involve the exchange or sharing of electrons likecovalent and ionic ...

A DNA palindrome thus refers to a string of DNA letters, or bases — A (adenine), C (cytosine), G guanine) and T (thymine) — that are the same when read forward on one strand and read backward on the other. For example, if one strand reads "GATC" in one direction, these DNA...
Nitrogenous bases Guanine (G) and adenine (A) belong to the purine family. Pyrimidine: Cytosine (C), thymine (T), and uracil (U) are examples of pyrimidines because they all are derived from a six-membered pyrimidine ring. Purines Pyrimidines 2 cyclic carbon-nitrogen rings 1 cyclic ...
Assign a nucleotide to each colored toothpick. For example, red can be adenosine (A), green can be guanine (G), blue can be thymine (T) and yellow can be cytosine (C). Step 2 Create 20 nucleotide pairs by pressing one toothpick into either side of a mini-marshmallow. The marshmallow...
Deoxyribonucleic acid or DNA is the genetic material in almost all living organisms. It is made of four bases, thymine (T), adenine (A), guanine (G), and cytosine (C). They are held together by a covalent bond and have a sugar-...
