Two alleles of a given gene exist in a population: CTGT and TGTC. (Note: The codes given are only for the transcribed strand of

the DNA in the two alleles.) Three possible single crossover events are possible between these two alleles. As a result of the three different crossover events, how many total new alleles (new sequences of DNA) could be produced?
A. 3.
B. 4.
C. 5.
D. 6.

Explanation:

<u>D. 6</u>

There are two forms of the gene, CTGT and TGTC, called alleles. These have undergone 3 crossover events, which may create two separate copies.

Thus 2 × 3 (# of events)= 6 new alleles

The interchange of chromosome segments, including homologous non-sister or identical chromatids. Crossing over happens at chiasmata, where non-sister chromosomes are fused together.

Further Explanation:

DNA variants on chromosomes,may have different forms called alleles. DNA, which is a genotype, is transcribed into mRNA and then converted into amino acids that are linked together by rRNA to form proteins that make up the morphology of the individual.

g Indium has two naturally occurring isotopes: 113In with an atomic weight of 112.904 amu, and 115In with an atomic weight of 11
aleksandrvk [35]

Answer:

Fraction-of-occurrences of 115In isotope = 0.957

Explanation:

As we know  weight of 113 In  isotope is equal to the sum of product of fraction-of-occurrences of two constituents isotopes and their atomic weight

^{115}In_w = f_{113}*A_{113} + f_{115}*A_{115} ------(1)

As we know sum of fraction-of-occurrences of two constituents isotopes is equal to one.

f_{113} + f_{115} = 1\\f_{113} = 1- f_{115}---------(2)

Substituting the given values in equation 1, we get

^{115}In_w = f_{113}*A_{113} + f_{115}*A_{115}\\114.818 = (1 - f_{115}) * 112.904 + f_{115} * 114.904\\f_{115} = 0.957

Substituting this value in equation 2 we get -

f_{113} = 1- f_{115}\\f_{113} =  1- 0.957 \\f_{113} = 0.043

Why are finches important to Darwin's idea?
marissa [1.9K]
It helps to give solid evidence of natural selection. The idea is that there are a number of finches in the Galapagos Islands. These birds vary slightly in appearance, in the function of their beaks and in size. Two species can eventually alter themselves because of the environmental conditions they live in. Some traits will be passed on or developed in one group and not in the other or vica versa. These finches are remarkable in that it did not take long for the changes to take place. It is probably one of the strongest reasons for believing in natural selection, because only those birds who could adapt to change could easily pass on these advantages to their offspring. The relatively short period of time to enact these changes is what makes the this example  so attractive.
