AleksAgata [21]
The correct answer is C. Mitosis produces 2 genetically identical diploid cells, while meiosis produces 4 genetically unique haploid cells.

Mitosis is where a parent cell duplicates its genetic information before dividing into 2, therefore, the daughter cells from mitosis are completely identical to their parent cell and the other daughter cell, and we call the cells which has complete genetic information as diploid. Mitosis is very useful in repairing, growth, asexual reproduction etc.

Meanwhile, meiosis involves 2 times of division. The parent cell first duplicates its genetic information, but then swapping them, and divide. 2 new cells are produced. Then these 2 cells are further divided but without duplicating the genetic material. Therefore, this results in 4 genetically different cells. We call them haploid, as they only have half of the chromosomes from their parent, which is the opposite of diploid. Meiosis is important in producing sex cells.

Rzqust [24]

Answer: option D

In generalized transduction, any DNA can be moved while in specialized transduction certain DNA from the phage site is moved.

Explanation:

Transduction is the process where foreign DNA is added to a cell by a virus or viral vector.

Transduction is divided into two, generalized and specialized.

Generalized transduction is a process where any DNA can be transferred by the virus in the cell while specialized transduction is a process where a fragment of the DNA near the phage site can be moved.
