What must happen to a chromosome before a cell starts mitosis?
slamgirl [31]
The chromosome must be duplicated before mitosis.

Mitosis is where a parent cell divides and produces 2 genetically indentical daughters cells. This process first requires the parent call to duplicate all of its genetic material. This ensures that the daughters cells are genetically identical to the parent cell and also the other daughter cell.

This is important because mitosis is used in many cases in living things such as growth, repair, and more. This ensures us for example not suddenly changed to another organism or another characteristic.

sertanlavr [38]

Answer:

The correct answer is - option C.

Explanation:

CFTR is a short form of cystic fibrosis transmembrane conductance regulator protein which is caused by a recessive mutation in this protein. This mutation results in the accumulation of mucus in secretory organs.

As the disease is a recessive disease, for the mutant phenotype to expressed both copies of the allele required to be recessive.

The mother is negative for the CFTR. Hence, she will not transfer the mutant allele to her child So, the child would have a wild-type phenotype even if the father having two copies of recessive allele.

Thus, the correct answer is - option C.
