Question 1

Which of the following best describes chromatin?

Accepted Answer

Uncoiled DNA wrapped around proteins called histones.

Question 2

During which stage of binary fission does the DNA replicate?

Accepted Answer

Before the chromosomes segregate to opposite ends of the cell.

Question 3

What is the main function of the centromere during cell division?

Accepted Answer

To attach sister chromatids together.

Question 4

Which of the following is true about homologous chromosomes?

Accepted Answer

They are chromosomes of the same size and shape, containing the same genes but possibly different alleles.

Question 5

If a mutation occurs in the centromere region of a chromosome, which process is most likely to be affected?

Accepted Answer

Attachment of sister chromatids

Question 6

Which step in binary fission ensures that each daughter cell receives an identical copy of the genetic material?

Accepted Answer

Segregation of chromosomes

Question 7

A scientist observes a cell with uncoiled DNA and histones. What is the most likely state of this cell?

Accepted Answer

The cell is not dividing.

Question 8

Which of the following best explains why binary fission is considered a form of asexual reproduction?

Accepted Answer

It produces genetically identical offspring from a single parent.

Question 9

What would happen if the chromosomes did not segregate properly during binary fission?

Accepted Answer

One or both daughter cells might lack essential genetic information.

Question 10

Which of the following sequences correctly represents the order of events in binary fission?

Accepted Answer

DNA replication → Chromosome segregation → Cytokinesis

Question 11

If a prokaryotic cell fails to form a new membrane across the center after chromosome segregation, which process is disrupted?

Accepted Answer

Cytokinesis

Question 12

Which of the following structures is present in eukaryotic chromosomes but not in prokaryotic DNA?

Accepted Answer

Histones

Question 13

A cell is observed with condensed chromosomes aligned at the center. Which stage of the cell cycle is this cell most likely in?

Accepted Answer

Metaphase

Question 14

Which of the following best describes sister chromatids?

Accepted Answer

Identical copies of DNA attached at the centromere.

Question 15

Why is it important for chromosomes to condense during cell division?

Accepted Answer

To ensure accurate segregation of genetic material.
