The right answer is A.) nondisjunction

Non-disjunction is an absence of separation of two members of a pair of homologous chromosomes or chromatids from a chromosome during meiosis or mitosis, resulting in one of the daughter cells having two copies of the same chromosome or chromatids and the other daughter cell receives none.

Answer:

The team would have to replace the nucleus.

Explanation:

Prokaryotic cells, such as the Mycoplasma capricolum cell used in the experiment do not contain either membrane bound organelles or a defined nucleus. Prokaryotic DNA floats around freely in the cytoplasm in a region called the nucleoid.

The genetic material of eukaryotic cells is protected by a membrane bound nucleus. Therefore, in order to replace an animal cell's DNA, the whole nucleus has to be removed.

Example:

In the process of cloning, the oocyte (egg cell) that receives the nucleus (from somatic cell) of the desired species or individual has to be enucleated i.e. its own nucleus has to be removed. This process is called somatic cell nuclear transfer.
