Which of the following organisms can do binary fission?

• Human

• Bacteria

• Unicellular eukaryotes, such as yeast

• Plants

Which of the following is INCORRECT?

• All cells are microscopic, because cells need to be small enough to receive sufficient information from the DNA

• As cells get larger, the surface area to volume ratio gets larger, which makes it easier for cells to obtain from the environment

• All cells are microscopic, because larger cells have trouble removing waste efficiently

• Different types of cells typically have different functions and sizes

Which of the following is CORRECT?

• A prokaryotic cell can go through sexual or asexual reproduction

• Certain prokaryotic cells can have a nucleus

• A prokaryotic cell has one circular DNA as its genome

• A eukaryotic cell have multiple circular DNA as its genome

Which of the following does NOT describe a property of chromosomes?

• Chromosomes cannot be replicated

• Chromosomes are supercoiled DNA

• Chromosomes are made of DNA and histone proteins

• Condensed chromosomes are formed in eukaryotes but not prokaryotes

How would you describe B?

• B shows two sister chromatids on the same duplicated chromosome

• B shows two sister chromatids on two different chromosomes

• B shows two non-sister chromatids on the same duplicated chromosome
