Deoxyribonuclease is any enzyme that catalyses the hydrolytic cleavage of the phosphodiester bond links in the DNA back bone (aka the bits between the pentose's).

So because it shares the characteristics of a nuclease it has a mojor effect on the DNA itself. Depending on the specificity of the particular deoxyribonuclease it has the potential to dissintegrate a DNA polymer- essentially making it impossible for division.

This principle is why it is an effective enzyme to be inhaled by those suffering from Cystic Fibrosis.

What bacterial species produces Deoxyribonuclease?

The bacterial species that produces Deoxyribonuclease is Staphylococcus aureus. It is an enzyme that helps the bacteria break down DNA, allowing it to acquire genetic material from its environment.


What is deoxyribonuclease?

Deoxyribonuclease (DNase) is an enzyme that catalyzes the hydrolysis of DNA, breaking down its phosphodiester bonds and resulting in the degradation of DNA strands into smaller fragments. It plays a crucial role in various biological processes, including DNA repair, apoptosis, and the removal of excess DNA from cells. DNase is also used in laboratory applications, such as molecular biology and genetic research, to manipulate DNA for cloning and analysis.

Which polymers code for an organism trait?

The trait of an organism is coded for by genes, which are segments of DNA. These genes encode for specific proteins or traits, not polymers. Polymers are large molecules made up of repeating subunits, such as nucleotides in DNA or amino acids in proteins.


Which type of enzyme destroys the ability of the transforming principle to function?

DNase enzyme destroys the ability of the transforming principle to function by degrading DNA molecules.


Are DNA and RNA molecules considered monomers or polymers?

They are considered polymers. The monomers of nucleic acids (DNA and RNA) are nucleotides. Each nucleotide has a phosphate, a sugar and a nitrogenous base.

No, proteins are polymers of amino acids. DNA and RNA are polymers of nucleotides.


Are all polymers man made?

No, not all polymers are man-made. Some polymers can be found in nature, such as proteins, cellulose, and DNA. These natural polymers have unique properties and functions in living organisms.


Name some polymers that are produced in nature?

There are several polymers in living beings, for example, proteins, DNA, RNA, and polysaccharides.


Are carbohydrates proteins and DNA all polymers?

Yes, carbohydrates, proteins, and DNA are all polymers. Carbohydrates are composed of repeating units of sugars, proteins are composed of amino acids, and DNA is composed of nucleotides. Each of these molecules is made up of long chains of these repeating units linked together.
