Genetic Change in Viruses. Viruses are continuously changing as a result of genetic selection. They undergo subtle genetic changes through mutation and major genetic changes through recombination. Mutation occurs when an error is incorporated in the viral genome
<span>The question is asking us to fill in the gaps in the following sentence: When a person loses consciousness due to a head injury from a car crash, the (gap) keeps the body functioning by regulating the flow of information between the brain and the rest of the body. The best answer is that the gap should be filled by "autonomous nervous system" - this system is the one that is not controlled consciously, but one that is working in the background to make sure our body functions work properly.</span>
RNA and DNA-RNA hybrids are more dense than simply DNA if the density of different nucleic acids is tested using a CsCl gradient.
The primary technique employed in molecular biology is the extraction of DNA, RNA, and protein. Scientists can separate materials according to size, shape, and density by using density gradient centrifugation. Isopycnic centrifugation, a sort of density gradient centrifugation that Meselson and Stahl developed, employed a cesium chloride solution to separate DNA molecules solely on the basis of density. Because DNA has hydrogen bonds between its strands, which makes it less dense than RNA, RNA has a far larger density than DNA. RNA can be obtained at the test tube's bottom using a CsCl density gradient and high centrifugation, whereas DNA can be recovered in the middle layer.

Explanation:
The control group is defined as the group in an experiment or study that does not receive treatment by the researchers and is then used as a benchmark to measure how the other tested subjects do.
The DNA technology that is helping in this process is the CRISPR-Cas system.
<h3>What is the CRISPR-Cas system?</h3>
The CRISPR-Cas system is a genome editing tool that has revolutionized genetic and molecular biology.
This genome editing tool can be used to insert specific sequences of DNA into a chromosome and thus generate a new cell expressing of these genes.
In conclusion, The DNA technology referred here is CRISPR-Cas system.
