Prokaryote vs Eukaryote

What is the primary difference between prokaryotic and eukaryotic chromosomes?

• Prokaryotic chromosomes are linear, while eukaryotic chromosomes are circular.

• Prokaryotic chromosomes are found in the nucleus, while eukaryotic chromosomes are found in the cytoplasm.

• Prokaryotic chromosomes are circular, while eukaryotic chromosomes are linear.

• Prokaryotic chromosomes contain histones, while eukaryotic chromosomes do not.

How many chromosomes do humans have in each somatic cell?

• 23

• 46

• 92

• 44

What is the function of histone proteins in eukaryotic chromosomes?

• To replicate DNA

• To transcribe DNA into RNA

• To package and organize DNA

• To mutate DNA sequences

In prokaryotes, the region where the chromosome is located is called the:

• Nucleolus

• Nucleus

• Nucleoid

• Mitochondrion

Which of the following statements is true about prokaryotic chromosomes?

• They are surrounded by a nuclear membrane.

• They contain introns.

• They are usually circular and double-stranded.

• They are associated with histones.

Which of the following organisms typically have a single circular chromosome?

• Plants

• Animals

• Bacteria

• Fungi

Telomeres are found at the ends of chromosomes and are important because they:

• Initiate DNA replication.

• Protect the ends of chromosomes from deterioration.

• Attach chromosomes to the nuclear membrane.

• Encode essential proteins.

Which of the following is a key feature of eukaryotic but not prokaryotic chromosomes?

• Presence of DNA

• Association with histone proteins

• Circular structure

• Single chromosome

The point on a chromosome by which it is attached to a spindle fiber during cell division is known as the:

• Telomere

• Centromere

• Nucleosome

• Chromatid

Which of the following best describes plasmids?

• They are main chromosomes found in eukaryotes.

• They are small, circular DNA molecules found in prokaryotes.

• They are proteins that help in chromosome packaging.

• They are membrane-bound organelles in eukaryotic cells.
