Answer:

A is a eukaryotic cell while B is a prokaryotic cell

Explanation:

The researcher can conclude that <u>cell A is eukaryotic while cell B is prokaryotic.</u>

In eukaryotic cells, the <u>DNA is located majorly in the nucleus and the replication of the DNA happens in the nucleus</u>. Hence, it is only logical to find segments of new DNA in the nucleus of cell A during replication.

<u>Prokaryotic cells, however, lack a nucleus</u>. Their DNAs lie freely within the cytoplasm. This thus means that replication can only happen in the cytoplasm. Hence, it follows logically to find a new DNA segment in the cytoplasm of cell B.

The mitotic cycle of somatic, or body, cells is responsible for the production of copies of those cells.

The G0 phase is described as the resting phase of a cell, where no activities relating to cell division are taking place. G0 phase cells remain in this phase their entire lives, so they do not divide. Another example of such a cell is found in red blood cells.
