Question

Genetically speaking, prokaryotes are different from eukaryotes because:

1) Prokaryotes have a nucleus, while eukaryotes do not.
2) Prokaryotes have membrane-bound organelles, while eukaryotes do not.
3) Prokaryotes have circular DNA, while eukaryotes have linear DNA.
4) Prokaryotes reproduce asexually, while eukaryotes reproduce sexually.

Answer 1

Prokaryotic cells lack a membrane-bound nucleus and contain circular DNA, while eukaryotic cells have a nucleus housing multiple linear chromosomes. Additionally, prokaryotes do not have membrane-bound organelles like eukaryotes and typically reproduce asexually.

Step-by-step explanation:

Genetically speaking, there are several differences between prokaryotes and eukaryotes. One of the main differences is that prokaryotes, such as bacteria and archaea, do not have a membrane-bound nucleus. Instead, their DNA, usually a single large circular chromosome, is located in the nucleoid region of the cell. In contrast, eukaryotic cells, which include animals, plants, fungi, and protists, have multiple linear chromosomes housed within a membrane-bound nucleus. Moreover, eukaryotic DNA is associated with histone proteins and can form complex structures such as heterochromatin, which is not present in prokaryotes.

Another difference is that prokaryotic cells lack other membrane-bound organelles found in eukaryotic cells. Additionally, while prokaryotes commonly reproduce asexually through processes like binary fission, eukaryotes can reproduce both sexually and asexually depending on the organism.
