DNA is a genetic material found in every living organism. DNA is made up of purines, pyrimidines, a pentose sugar, and phosphate backbone. DNA is a genetic material that carries information from parent to daughter cells.
Characteristics of the DNA include:
1. DNA is a double-stranded genetic material, which is made up of four nitrogenous bases, adenine, cytosine, thymine, and guanine.
2. These nucleotides bind to specific nucleotide sequences present on the template strand of the DNA.
3. DNA consists of coded sequences known as genes, which are inherited from the parent to the daughter cells.
4. DNA undergoes a unique semi-conservative mode of replication.
