Nucleus of a donor embryonal cell/ somatic cell is transferred to a an enucleated egg cell. Then after the formation of organim , what shall be true ?

Options

A. Organism will have extra - nuclear genes of the donor cell
B. Organism will have extra - nuclear genes of recipient cell
C. Organism will have extra - nuclear genes of both donor and recipient cell
D. Organism will have nuclear genes of recipient cell

Explanation

To solve the question regarding the transfer of a nucleus from a donor embryonal or somatic cell to an enucleated egg cell, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Understanding the Cells Involved**:
- There are two types of cells in this scenario: the donor cell (which contains the nucleus) and the recipient cell (the enucleated egg cell, which has had its nucleus removed).

2. **Nucleus Transfer**:
- The nucleus from the donor cell (which could be an embryonal or somatic cell) is transferred into the enucleated egg cell. This means that the egg cell now contains the genetic material from the donor cell.

3. **Formation of the Organism**:
- After the nucleus transfer, the enucleated egg cell, now containing the donor cell's nucleus, can undergo development to form an organism. This process is similar to cloning, where the genetic information from the donor cell is used to create a new organism.

4. **Genetic Composition of the Organism**:
- The resulting organism will have the genetic material (nuclear genes) from the donor cell. Since the egg cell was enucleated, it does not contribute any nuclear genes to the organism.

5. **Extra Nuclear Genes**:
- The term "extra nuclear genes" refers to genes that are not present in the nucleus of the egg cell. In this case, the organism will have the nuclear genes from the donor cell, and since the egg cell does not contribute any nuclear genes, it can be said that the organism has "extra nuclear genes" from the donor cell.

### Conclusion:
- The final statement that can be made is: **The organism will have extra nuclear genes from the donor cell.**
