Final answer:
Courtney has discovered a prokaryotic cell, which contains DNA in a nucleoid but lacks a nucleus, unlike eukaryotic cells which have a nucleus housing their DNA. Therefore , the correct answer options is c)
Step-by-step explanation:
During the science experiment, Courtney believes she may have found a new cell which contains DNA and has a nucleoid region but does not have a nucleus. The type of cell Courtney is looking at would be classified as a prokaryotic cell.
Prokaryotic cells, such as those found in bacteria and archaea, lack a nucleus and other membrane-bound organelles. Instead, the DNA of prokaryotic cells is located in the central part of the cell called the nucleoid. The correct answer to Courtney's question is c. prokaryotic.
