Multiple Choice

Which statement best describes chromosomes and their differences between prokaryotes and eukaryotes?

Chromosomes are found only in eukaryotes and are always circular in shape.

Chromosomes are structures made of DNA and proteins; prokaryotes typically have a single circular chromosome, while eukaryotes have multiple linear chromosomes.

Chromosomes are protein-only structures; prokaryotes lack chromosomes, but eukaryotes have them.

Chromosomes are made only of RNA; both prokaryotes and eukaryotes have the same number and shape of chromosomes.

Verified step by step guidance

Understand what chromosomes are: Chromosomes are structures composed of DNA and proteins that carry genetic information in cells.

Recognize the difference in chromosome structure between prokaryotes and eukaryotes: Prokaryotes usually have a single circular chromosome, while eukaryotes have multiple linear chromosomes.

Note that chromosomes are not made only of proteins or RNA; they are primarily DNA wrapped around proteins (like histones in eukaryotes).

Recall that chromosomes are found in both prokaryotes and eukaryotes, but their number, shape, and complexity differ.

Use this knowledge to evaluate the given statements and identify the one that correctly describes chromosomes and their differences between prokaryotes and eukaryotes.
