Question

which of the following describes a key difference in the organization of genetic material between prokaryotic and eukaryotic cells? prokaryotic dna is enclosed within a nucleus, while eukaryotic dna is free in the cytoplasm. prokaryotic dna contains introns, while eukaryotic dna does not. eukaryotic dna is circular, while prokaryotic dna is linear. eukaryotic dna is enclosed consider a cell that lacks a nucleus and any other membrane - bound organelles. based on these characteristics, this cell would be classified as a: animal cell plant cell prokaryotic cell eukaryotic cell

Explanation:

1. In prokaryotic cells, DNA is free - floating in the cytoplasm, while in eukaryotic cells, DNA is enclosed within a nucleus. Prokaryotic DNA is usually circular and lacks introns, whereas eukaryotic DNA is linear and has introns. So, for the first question, the correct difference is that eukaryotic DNA is enclosed within a nucleus.
2. Prokaryotic cells lack a nucleus and membrane - bound organelles, while eukaryotic cells (animal and plant cells are eukaryotic) have a nucleus and membrane - bound organelles. So, a cell lacking a nucleus and membrane - bound organelles is a prokaryotic cell.

Answer:

1. Eukaryotic DNA is enclosed within a nucleus.
2. Prokaryotic cell
