Answer:
The correct answer is: Nuclease (DNAse or RNAse).
Explanation:
- Virus particles are majorly made up of two components:
- Capsid: It can be defined as a glyco-protein rich coat that encloses the viral particles.
- Genetic material: It can be DNA (Deoxyribonucleic Acid) or RNA (Ribonucleic Acid). It can be either in the form of single strand or in the form of double strand.
- The genetic material is the infectious component of the viruses. This is because if the viral genetic material gets access into the host cell, it can hijack the host cell machinery to produce new viral particles thereby causing infection in the host.
- Therefore, in order to destroy viral particles it is necessary to destroy its genetic material, that is, DNA or RNA.
- Nuclease is the enzyme which is capable of hydrolysing and hence degrading the nucleic acids.
- The nuclease specific for DNA is called DNase.
- The nuclease specific for RNA is called RNase.
- Depending upon the type of virus, DNA virus (having DNA as the genetic material) or RNA virus (having RNA as the genetic material), either DNAse or RNAse needs to be used for destroying the virus.
Answer:
Fossils are the greatest and simplest evidence of the presence of the organisms that existed many years ago.
Deoxyribo Nucleic Acid (DNA) is called as “coil of life.” According to the Darwin’s theory about 8 percent of human genome is made up from viral DNA which a person has accumulated through infections and diseases.
The case studies helps in figuring out the total evolution of species and organisms.
<u>Explanation:
</u>
<em>Fossil Records
</em>
But now Fossils are the feces and the footprints of the organisms which confirm the presence of an organism which are now extinct or rare to find.
<em>DNA evidence
</em>
DNA of an organism has sequences which mutate over a period of time and results in changes in organism’s genetics which later on evolve into new specie. Hence, the DNAs help to find the ancestors of the organism and also figure out the organism specifically related to. The process of study of evolution is known as Phylogenetics.
<em>Case Studies
</em>
The finch of Galapagos of Darwin’s is one of such example of evolution. The Galapagos Island helped in finding out the evolution occurred when the finches were secluded due to the geographical barriers.
Answer:
All molecular motion stops at 0 degrees Kelvin or -273.15 degrees Celsius.
