You are given two solutions containing different purified DNAs. One is from the bacterium P. aeruginosa and has a G + C composit

ion of 68%, whereas the other is from a mammal and has G + C composition of 42%. You measure the UV absorbance of each solution as a function of increasing the temperature. Which solution will yield the higher Tm value and why?

4 0

Answer:

The solution of P. aeruginosa will yield higher Tm value.

Explanation:

The solution of P.aeruginosa contain 68% G+C composition as a result the DNA of P.aeruginosa is more stable than the DNA of mammal contain only 42% G+C composition.G+C composition is most stable because guanine is linked to cytosine by 3 hydrogen bonds whereas adenine linked to thymine by 2 hydrogen bonds.

   As  P.aeruginosa DNA is more stable than mammalian DNA,as a result the DNA solution of P.aeruginosa will yield high Tm(melting temperature) value than that of mammalian DNA.

Gene testing is foolproof since it scans the building blocks of humans. Please select the best answer from the choices provided.
Harrizon [31]

False

reason -

Gene testing is not full proof as there are  possibilities of discrepancies in it based on the testing procedures used and the condition of sample. Since we human beings have the same genomic structure there are chances that our DNA may match with other people who do not share a heredity with our family. Basically statistical probability is used to determine probability of paternity, relationship of any kind etc. among two individuals . usually A 99% or higher percentage of probability is considered conclusive. and thus it gene testing can not be considered as full proof
