Can deoxyribonucleic acid be destroyed?
In what sense ??If you treat DNA with the digesting enzyme DNAse, then the DNA is gone!-I have to say DNA is very stable than RNA though.
Is serratia marcescens dnase positive or negative?
Serratia genus as a whole is dnase positive.
What is the difference between DNA and DNase?
DNA is a molecule that carries genetic instructions for the development, functioning, growth, and reproduction of all known living organisms. DNase, on the other hand, is an enzyme that specifically degrades and breaks down DNA molecules into smaller components. DNase is commonly used in molecular biology techniques to remove DNA contaminants from RNA samples.
Describe a positive DNase test?
A positive DNase test indicates the presence of DNase enzyme, which degrades DNA molecules. This is detected by a clear zone around the bacterial growth on DNase agar plate after adding a DNase indicator dye. The clear zone indicates that DNA in the medium has been hydrolyzed, suggesting the bacteria has the ability to produce DNase enzyme.
What is the reagent used to test Dnase test?
There are no reagents added when a Dnase test is performed. The test is done in a methyl green medium with a pure inoculum culture. If halos form around the culture than Dnase is present.
How can you tell if isolated RNA is free of DNA?
There is a DNA killing step in RNA isolation by the enzyme DNase I. This will make sure your preparation is free of DNA.

What is DNAse?
DNAse is an enzyme that breaks down DNA molecules by cleaving the phosphodiester bonds between nucleotides. It is used in molecular biology and biotechnology applications to remove DNA contamination from RNA samples, or to digest DNA in cell lysates for various experimental purposes. DNAse is essential for processes like DNA replication, repair, and recombination in cells.

Why 1M of HCL is used in Dnase test?
Hydrochloric acid (HCl) is used in DNase tests to denature proteins that may inhibit the enzyme DNase. By denaturing proteins, the HCl helps to create an environment that is more conducive for the DNase enzyme to work effectively in degrading DNA. Using 1M of HCl provides an optimal concentration for denaturing proteins without affecting the stability and activity of DNase.

Does human hands contain DNAse enzyme?
Yes, human hands contain DNAse enzymes. DNAse enzymes are involved in breaking down and degrading DNA molecules. In the human body, DNAse enzymes can be found in various tissues and cells, including skin cells in the hands.

There are no reagents added when a Dnase test is performed. The test is done in a methyl green medium with a pure inoculum culture. If halos form around the culture than Dnase is present.
Role of EDTA in DNA isolation?
it is chealeting agent and has great affinity with metal ions and mg- ions present in dnase as a cofactor and responsible for dnase action that degreded DNA hear edta bide with mg- ions and stop the action of dnase.
What enzyme is responsible for deplolymerization for DNA?
DNase I: deoxyribonuclease
How do you kill RNA?
RNA can be degraded by using enzymes like RNase, which specifically breaks down RNA molecules. Additionally, RNA can be degraded by exposure to high temperatures or extreme pH conditions that destabilize the molecule. It can also be fragmented by physical methods such as sonication or mechanical disruption.
