Nitrogenous Base
the part of DNA that makes up the “rungs” of the ladder like structure; the four nitrogenous bases found in DNA are adenine (A), thymine (T), guanine (G), and cytosine (C)
Nitrogenous bases are compounds that contain nitrogen atoms and are necessary components of nucleotides, which in turn make up the genetic material of all living cells. There are four types of nitrogenous bases: adenine, guanine, cytosine, and thymine. These nitrogenous bases pair specifically with one another to form the rungs of the DNA ladder, allowing the sequence of bases to be read by cell machinery.
Adenine and guanine are purine bases, which means they have a double-ring structure, while cytosine and thymine are pyrimidine bases, meaning they have a single-ring structure. Adenine always pairs with thymine (A-T), and guanine always pairs with cytosine (G-C), through hydrogen bonding.
Nitrogenous bases are important for DNA replication, transcription, and translation. During DNA replication, the bases pair up according to complementary base pairing, which ensures that the new DNA molecule is identical to the original. During transcription, the DNA sequence is read and used to produce an RNA molecule. The RNA molecule contains a copy of the nitrogenous bases, which is used to create a protein during translation.
Overall, nitrogenous bases are essential components of DNA and RNA and play a critical role in the transmission of genetic information from one generation to the next.
