The four nitrogen bases are Adenine, Thymine, Cytosine, and Guanine. Their job is composing a code for DNA to shape the physical characteristics of most living things.
The number of nitrogen bases in a bacterial genome can vary depending on the species of bacteria. On average, a bacterial genome may contain around 1 to 10 million nitrogen bases. These nitrogen bases make up the genetic code of the bacteria and are responsible for encoding the information necessary for the bacteria to function and reproduce.
The attraction between two nitrogen bases across the center of the DNA helix is called hydrogen bonding. This bonding occurs specifically between complementary nucleotide bases, such as adenine pairing with thymine and cytosine pairing with guanine.
The nitrogen bases, adenine, uracil, guanine, thymine and cytosine are joined to each other via phosphodiester bonds. Hydrogen bonds hold the nitrogen bases in complementary DNA and RNA strands. Polypeptide bonds are formed between an amide and ketone, and these join amino acids in proteins. However, they do not hold nitrogen bases together.
The order of nitrogen bases in DNA determines the sequence of amino acids in proteins, which are essential for the structure and function of cells. Each set of three bases, called a codon, codes for a specific amino acid. Variations in these sequences can lead to differences in protein structure and function, ultimately influencing an organism's traits. Thus, the arrangement of nitrogen bases directly impacts genetic expression and the characteristics of an organism.
Hydrogen Bonds
Hydrogen bonding occurs between the nitrogenous bases in the DNA molecule. Specifically, hydrogen bonds form between adenine and thymine (or uracil in RNA), as well as between guanine and cytosine. These hydrogen bonds are important for maintaining the double helix structure of DNA.
