A genetic engineer needs to use gene therapy to help a person with cystic fibrosis. Arrange the following steps in the order the engineer would use them.a. Use only the steps you need. Inject the modified CFRT gene into a fertilized egg and implant into a woman who will be the surrogate mother.
b. Combine the cloned CFRT gene with a disarmed respiratory virus.
c. Clone the CFRT gene from someone with cystic fibrosis.
d. Clone the CFRT gene from someone without cystic fibrosis.
e.Modify the CFRT gene by putting on a different promoter
f. Test the patient’s blood cell DNA with PCR to see if they have the CFRT transgene.
g. Have the patient use an inhaler that contains the modified respiratory virus.

Answers

Answer 1
Answer:

Answer:

d-b-g-f

Explanation:

1. Clone the CFRT gene from someone without cystic fibrosis.

This will make millions of copies of the gene (wild type, not being mutated and thus unable of producing the disease).

2. Combine the cloned CFRT gene with a disarmed respiratory virus.

This step will allow the virus to transport the gene of interest.

4. Have the patient use an inhaler that contains the modified respiratory virus.

This step helps the virus to enter and infect the patient's cells and thus allowing the copies of the transgene to be integrated into the patient's genome.

3. Test the patient's blood cell DNA with PCR to see if they have the CFRT transgene.

This will confirm if the transgene has actually been integrated into patient's genome.

By 1898, the 95% of the moths in Manchester and other highly industrializedareas were of the dark color.

A. 4
B. 2
C. 3
D. 1

Answers

An experimental pharmaceutical is typically approved after it passes 4 phase of clinical trials.

What is clinical trial ?

Clinical trials are combination of new research, studies and experiments performed in people to evaluate the effectiveness of new experiment on human health.

It consists of main 4 phases.

Phase 4 clinical trial is also known as " Post-Approval Research and Monitoring ". It is the final stage of trial for any pharmaceutical product, drug or device. This trial study about the side effects, real life scenarios, long-term risks and benefits of particular pharmaceutical product which were not seen in the early trials.

So we can sayan experimental pharmaceutical can be approved when it passes 4 phases of clinical trials.

1. What is the equation for the equilibrium constant, Keq, for the following general reaction: aA + bB → cC + dD Define each term in the equation. 2. What is the actual free energy change of the reaction above? Again, define each term in the equation. Express this equation in terms of mass action Q
3. What is the standard free energy change of the reaction above? Again, define each term.

Answers

Answer:

Explanation:

From the reaction ; aA + bB → cC + dD

1) Keq = equilibrium constant = [A]^a [B]^b / [C]^c [D]^d

where [A] = [B] = [C] = [D] are the concentrations of reactants A, B, C and D respectively.

2) What is the actual free energy change of the reaction above? ;

  • ΔG is the differences between the sum of the free energies of the product and the reactant.
  • Mathematically; ΔG = (cΔGC + dΔGD) - ( aΔGA + bΔGB)
  • ΔG, in terms of reaction quotient ; ΔG = ΔG(standard) + RT lnQ

where R = gas constant and T = temperature.

3) What is the standard free energy change of the reaction above;

  • ΔG(Reaction) = Summation ΔGf(products) - summation ΔGf(reactants)
  • where summation ΔGf = standard free energy of formation

based on the phylogenetic tree, identify approximately how many millions of years ago the earliest South Asian river dolphin evolved. Round your answer to the nearest whole number

Answers

About 0.55 million or 550,000 years ago the earliest South Asian river dolphin evolved.

About 0.5 million years ago the South Asian dolphin evolved due to different environmental conditions. South Asian dolphin have very flexible necks due to no fusion of their neck vertebrae. They are using echolocation to navigate and search for prey.

Research indicates that  South Asian dolphin diverged from a common ancestor around 550,000 years ago that lives in the Indus and Ganges basins so we can conclude that the South Asian dolphin evolved around 0.55 years ago.

cientists classify clams as consumers. Which observation about clams provides the strongest evidence for this classification? A. Young clams are able to move from place to place. B. Clams gain energy and nutrients by filtering particles from the water. C. Clams use calcium compounds to make a hard shell. D. Clams live on the ocean floor, and sometimes survive without sunlight.

Answers

Answer:

The correct answer is option - B.

Explanation:

Clams are the bivalve mollusks that are classified as a consumer or the filter feeder as they internalize the particles and the suspended nutrients and matter in the water to carry out energy and nutrients for them.

These are known as a consumer due to their bivalve body and get its specific structure which is using gills to filter the food or nutrients particle. This makes the clams unique as some other bivalves organisms.

Thus, the correct answer is option - B.

The strongest evidence that classifies clams as consumers is that they gain energy and nutrients by filtering particles from the water.

WHAT ARE CONSUMERS:

  • Consumers are a group of organisms that are incapable of synthesizing their own food, hence, they depend on other organisms for source of energy by feeding on them.

  • A consumer can be a primary consumer, secondary consumer or tertiary consumer. Primary consumers feed on producers directly while secondary consumers feed on primary consumers and so on.

  • Therefore, an organism is classified as a consumer on the basis of its mode of nutrition.

  • Hence, the strongest evidence that classifies clams as consumers is that they gain energy and nutrients by filtering particles from the water.
