There are four different kinds of DNA nitrogenous bases found in all life on Earth: adenine (A), thymine (T), cytosine (C), and guanine (G). Each base pairs specifically with its complementary base to form the double helix structure of DNA.

Four kinds of nitrogenous base?

The four nitrogenous bases found in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair up in specific combinations to form the "rungs" of the DNA double helix, with adenine pairing with thymine and cytosine pairing with guanine.

What are the four bases found DNA?

adenine----The four nitrogenous bases that comprise DNA are adenine, guanine, thymine, and cytosine. there are four kinds of nitrogenous bases in dna. two of the nitrogenous bases, adenine and guanine,belong to a group of compounds known as purines. the remaining two bases, cytosine and thymine, are know as pyrimidines. Adenine pairs up with thymine, and cytosine pairs up with guanine. Humans also use a fifth base in RNA called uracil. In the case of RNA, thymine is replaced by uracil and other three bases remains the same. All of these bases are attached to the sugar and phosphate. The double helix maintains a constant width because purines always face pyrimidines in the complementary A-T and G-C pairs. And they are all connected by a phosphorous base. A-T; G-C The phosphorous base can be broken for DNA replication purposes.

Why are there four different kinds of nucleotides?

Great Question! Short Answer for now: there are practically innumerable types of atomic configurations that form nucleic acid conformations. Out of that biochemical multitude just four were selected; just as from a similar number of possible amino-acid configurations, just 20 were selected.


How many different kinds of atoms occur naturally on earth and why so?

There are 118 different kinds of atoms that occur naturally on Earth, known as elements. This is because of the unique number of protons in the nucleus of each atom, which determines the element's identity. The various combinations of protons, neutrons, and electrons give rise to the different elements found in nature.

In terms of their nitrogenous base component how many different kinds of RNA molecules are there?

There are three main types of RNA molecules based on their nitrogenous base component: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). Each of these types plays a specific role in the process of protein synthesis within cells.
