Layer D is the youngest layer
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.
