A certain strain of E. coli is constitutive for the enzymes for lactose metabolism. On an F' plasmid you have the choice of adding one (but only one) element of the lac system to make the bacteria a merodiploid for that element. Assume the original E. coli has wild-type structural loci. If your goal is to determine whether the lac operon is constitutive because of a mutant regulator OR because of a mutant operator, which one wild-type element of the lac operon would you add using sexduction?
a. operator region
b. regulator (repressor)
c. gene promoter region
d. structural genes
Answer:
The correct option is B: regulator (repressor)
Explanation:
A regulator gene would be required to control the expression by either increasing or decreasing the transcription of that particular gene. In doing so, the amount of protein product made by the gene can be regulated. In the wild-type case, the gene lacl is responsible for generating the mRNA which translates to a Lac repressor protein that binds at the operator region.

a) the F1 generation;
b) the F2 generation;
c) the progeny of a cross of the F1 plants back to the white, spiny parent; and
d) the progeny of a cross of the F1 back to the purple, smooth parent.
Answer:
See attached image for detailed punnet squares and diagrams
a) F1 generation: Purple flower and spiny pods (PpSs) offsprings
b) F2 generation: Puple flower, spiny pods (9), Purple flower, smooth pods (3), White flower, spiny pods (3), white flower, smooth pods (1).
c) The progenies are: PpSS (4), PpSs (4), ppSS (4), and ppSs (4)
d) The progenies are: PPSs (4), PPss (4), PpSs (4), Ppss (4)
Explanation:
This question involves two distinct genes in jimsonweed; one coding for flower colour and the other for pod texture. The alleles for purple colour (P) and spiny pods (S) are dominant over the alleles of white flower (p) and smooth pods (s) in the two genes respectively.
A true-breeding plant with white flowers and spiny pods will have genotype: ppSS while a true-breeding plant with purple flowers and smooth pods will have genotype: PPss. In a cross between these two parents, the following combinations of gametes will be produced:
ppSS- pS, pS, pS and pS
PPss- Ps, Ps, Ps, PS
a) Hence, the F1 offsprings from this cross will possess a heterozygous genotype: PpSs, which is phenotypically purple-flowered and spiny-pod.
b) if the F1 offsprings are self-crossed i.e. PpSs × PpSs, gametes PS, Ps, pS, ps will be produced by each parent. These gametes will be used in a punnet square (see attached image) to produce the following F2 offsprings in proportion:
Purple flower, spinny pods (9)
Purple flower, smooth pods (3)
White flower, spiny pods (3)
White flower, smooth pods (1)
c) if the F1 offsprings are crossed back with the white, spiny parent i.e. PpSs × ppSS. The following progeny of offsprings will be produced: (see attached image)
PpSS (4),
PpSs (4),
ppSS (4), and
ppSs (4)
d) if the F1 offsprings are crossed back with the purple, smooth parent i.e. PpSs × PPss, the following progeny will be produced:
PPSs (4),
PPss (4),
PpSs (4), and
Ppss (4)
The true breeding plant.
As per the question, the jimson weed is a purple flower with capital P and is dominant to white (p) and a spiny pods of (S) which are dominant to smooth (s). The Punnett square method is used for the method. The true breeding have seperate types of genetic make ups.
Answer is F1 generation (PpSs), F2 generation has 9 purple flowers.

In his deletion mapping experiments, Benzer coinfected bacteria with one phage that contained a point mutation and one phage that contained a deletion mutation. Assume that the point mutation and deletion mutation are not in overlapping regions of the phage genome. What phage recombinants would you expect if a crossing-over event occurred between the regions of the two mutations?
Answer:
The correct answer would be - there will be wild type and double mutant (contains both the deletion mutation and the point mutation)
Explanation:
It is mention that the deletion mutation and point mutation are non-overlapping or no overlapping regions in the phage genome. A crossing-over event between the regions of these two mutations would get wild-type which means there would be neither point mutation nor deletion mutation and other would be a double mutant that contains both mutation - the point mutation and the deletion mutation.
Thus, the correct answer is - there will be wild type and double mutant (contains both the deletion mutation and the point mutation)

How can changes on earths surface affect changes below surface
Answer:
There are several changes that occur on the earth's surface but also affects the changes below the surface, some of them are as follows:
When rainfall occur on the sandy surface on earth, it looses the soil under the surface and can cause landslides.Imbalance in the food chain above or on the earth surface can affect the nutrient quantity below the surface that is essential for soil bacteria and other microorganisms.Deforestation can also loosen the soil and soil under surface can shift its position.Use of chemicals on agriculture surface can lead to change the fertility of soil below the surface.Yellow dung flies (Scathophaga stercoraria) are diploid organisms with 12 chromosomes in their diploid cells. Without taking into account recombination, how many different genetic gametes can this fly generate based on the arrangement of its chromosomes in the metaphase plate during meiosis
In the given case, the sum of the number of gametes possible in the fruit fly is 2¹² or 4096.
Determination of the number of genetic gametes:
At metaphase I, the arrangement of chromosomes takes place at the equatorial plate and at the equator, the orientation of homologous pairs takes place randomly. This orientation helps in finding the genes found within a gamete as each of the gametes will get only one chromatid of a chromosome.
Now by independent assortment, the variation occurs within the gametes, which suggests that the alleles of distinct genes separate independently from one another at the time of cell differentiation. Due to independent assortment, the number of different kinds of gametes possible within the chromosomes can be determined by using the formula, 2ⁿ, where n is the number of chromosomes present within a set.
Thus, based on the given information, the number of chromosomes present in a fruit fly is 12. Thus, the sum of the number of gametes possible in the mentioned fruit fly is 2¹² or 4096.
