What are the names of the 4 nitrogenous bases in DNA?
The four nitrogenous bases in DNA are adenine (A), thymine (T), guanine (G), and cytosine (C)
The four nitrogenous bases in DNA are adenine (A), thymine (T), guanine (G), and cytosine (C). These bases are the building blocks of the DNA molecule and they form the genetic code that carries the instructions for the development and functioning of all living organisms.
Adenine and guanine are classified as purine bases, which consist of a double-ring structure. Thymine and cytosine are classified as pyrimidine bases, which consist of a single-ring structure.
In DNA, adenine always pairs with thymine, forming two hydrogen bonds, while guanine always pairs with cytosine, forming three hydrogen bonds. This complementary base pairing is crucial in DNA replication and the accurate transmission of genetic information during cell division.
Understanding the names and structures of these nitrogenous bases is essential in comprehending the fundamentals of DNA structure and function in the field of molecular biology and genetics.
