Which of the following choices correctly compares prokaryotic and eukaryotic chromosomes?

Question

(1 point)
• Prokaryotic chromosomes are linear while eukaryotic chromosomes are circular.
• Prokaryotic chromosomes are typically much larger than eukaryotic ones.
• Prokaryotes tend to only have one chromosome while eukaryotes have many.
• Prokaryotic chromosomes are wrapped into structures called nucleosomes.

Answer 1

The choice that correctly compares prokaryotic and eukaryotic chromosomes is:

• Prokaryotes tend to only have one chromosome while eukaryotes have many.

In more detail:

• Prokaryotic chromosomes are typically circular and not linear.
• Prokaryotic chromosomes are generally smaller than eukaryotic ones.
• Nucleosomes, which are structures formed by wrapping DNA around histone proteins, are characteristic of eukaryotic chromosomes, not prokaryotic ones. Prokaryotes do not have nucleosomes.

So, the correct option highlights that prokaryotes typically have a single chromosome while eukaryotes have multiple chromosomes.
