DNA is a nucleic acid. DNAse is a protein. DNA is deoxyribonucleic acid which is the hereditary material in all organisms except few viruses. DNAse is a deoxyribonuclease, it is an enzyme that catalyzes the hydrolytic cleavage of phosphodiester linkages in the backbone of DNA.

DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.

In all living things, DNA is essential for inheritance, coding for proteins, and providing instructions for life and its processes. DNA dictates how a human or animal develops and reproduces, and eventually dies.

DNA is pivotal to our growth, reproduction, and health. It contains the instructions necessary for your cells to produce proteins that affect many different processes and functions in your body. Because DNA is so important, damage or mutations can sometimes contribute to the development of disease.

The main parts of a nucleotide are the nitrogenous base and sugar-phosphate backbone. A viable nucleotide can’t form without them. Thus, they both have equal importance.

However, bacterial DNA is found in two forms: a chromosomal loop and plasmids. The chromosomal loop is a looping strand of DNA that contains most of the genes and is important in cell division and sits in cytoplasm, the fluid filling a single cell in the absence of a nucleus.

Prokaryotes generally have a single circular chromosome that occupies a region of the cytoplasm called a nucleoid. They also may contain small rings of double-stranded extra-chromosomal DNA called plasmids.

How Many Named Species of Bacteria are There? There are about 30,000 formally named species that are in pure culture and for which the physiology has been investigated.

They can be divided into six major types: bacteria, archaea, fungi, protozoa, algae, and viruses.

Bacterial disease

• Bacteria.
• Infectious disease.
• Cholera.
• Leprosy.
• Tuberculosis.
• Plague.
• Syphilis.
• Anthrax.

Bacteria are identified routinely by morphological and biochemical tests, supplemented as needed by specialized tests such as serotyping and antibiotic inhibition patterns. Newer molecular techniques permit species to be identified by their genetic sequences, sometimes directly from the clinical specimen.
