You are given two solutions containing different purified DNAs. One is from the bacterium P. aeruginosa and has a G + C composit
bonufazy [111]

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.

In humans, a type of blindness is due to a dominant allele; normal vision is the result of a recessive allele. Migraine headache
yan [13]

Answer:

Yes.

Probability of such child = 1/2 or 50%

Explanation:

According to the question, below are the genotypes and phenotypes possibilities:

aa = normal vision & no headache

Aa = normal vision & no headache

AA = blindness & headache

                                                                      Male                       Female

                                                                        Aa                            aa

Possible genotypes of progeny:            Aa        Aa           aa         aa

So it is clear that out of the 4 probable children, 2 with 'genotype aa' will have normal vision & no headache.

Mathematical expression is as under:

2/4 = 1/2 that means 50% progeny.
