Put the following procedures of gene therapy in order:

a. The healthy gene is delivered to a cell in an inactivated virus.

b. Researchers determine which gene is mutated and causes the disease.

c. The functioning protein is used in the cell.

d. The cell starts copying the healthy gene.

Here's what I got:

1. B
2. A
3. ?
4. ?

Please help thank you.

I'd put B,A,D,C

to confirm.

To order the procedures of gene therapy correctly, we need to understand the sequence of events involved. Here's the correct order:

1. Researchers determine which gene is mutated and causes the disease. (B)
2. The healthy gene is delivered to a cell in an inactivated virus. (A)
3. The cell starts copying the healthy gene. (D)
4. The functioning protein is used in the cell. (C)

Explanation:

First, researchers need to identify which specific gene is responsible for causing the disease or disorder. This involves studying the patient's genome and identifying the specific mutation. (B)

After identifying the mutated gene, a healthy copy of this gene needs to be delivered into the patient's cells. This is achieved by packaging the healthy gene into an inactivated virus, which acts as a vector to deliver it into the targeted cell. (A)

Once the healthy gene is delivered into the cell, it needs to be integrated into the cell's genome. The cell recognizes the healthy gene and starts copying it, allowing the production of the functional protein encoded by this gene. (D)

Finally, the functional protein, produced using the instructions from the healthy gene, is utilized by the cell to restore its normal function and potentially alleviate the effects of the genetic disorder. (C)

So, the correct order is B, A, D, C.
