Which step can occur even more rapidly by PCR?a. target DNA removed from cells and isolated b. cloning host treated with calcium
chloride and receives plasmid c. target DNA and plasmid treated with the same restriction endonuclease d. desired protein is produced by cloning host e. gene is amplified by multiplication of cloning host
E. Gene is amplified by multiplication of cloning host
Explanation:
PCR is a very powerful technique that can help us to amplify exponentially one gene from a very small sample of DNA.
As seen in the attached image, the process begins with a single DNA molecule, for the first cycle, that DNA molecule denaturalizes into two strands, the primers bind to their complementary sides and then the DNA polymerase builds the new DNA strands. The number of copies of the gene that can be obtained with each cycle are 2ⁿ copies, where n is the cycle number.
How did geological gradualism and uniformitarianism influence Darwin?
Darwin stated that evolution through natural selection through gradual change from the environment. This is like uniformitarianism where things, that change, change at a constant rate.
The difference is the shape and the jobs of the cell for example the white blood cell kills bad germs and sometimes helps scabs form and the red blood cell is to give oxygen to the body
A parasitic relationship is a type of relationship in which one organism, the parasite, lives off of another organism, the host, harming it and possibly causing death.
The organism that is harming the other one is called a parasite. Examples of Parasitism includes fleas or ticks that live on dogs and cats are parasites.
In this case; the organism that lives in the gills of a fish consuming fish's blood is the parasite, while fish is the host.
