 What is the genetic material found inside a virus?
 

DNA or RNA 

100

What phase of the cell cycle is the cell growing and preparing to divide?

Interphase


100

During which phase do chromosomes condense and become visible?

Prophase

100

What are the four main types of macromolecules?

Carbohydrates, Lipids, Proteins, Nucleic Acids

100

What is the main function of carbohydrates in organisms?

Provide Energy 

200

True or False: Viruses are considered living organisms because they can reproduce on their own.

False 

200

During which phase does the cell actually divide its nucleus?

Mitosis 


200

In which phase do chromosomes line up in the middle of the cell?

Metaphase

200

What is the monomer of proteins?

Amino acids

200

Which biomolecule is primarily responsible for storing genetic information?

Nucleic Acids 


300

What protein coat surrounds the genetic material of a virus?

Capsid 


300

Name the three main checkpoints in the cell cycle.

G1 Checkpoint 

G2 Checkpoint 

M Checkpoint 


300

What phase is characterized by the separation of sister chromatids?

Anaphase

300

Which macromolecule is primarily found in fats and oils?

Lipids

300

Proteins can function as enzymes, structural components, and what else?

Hormones, transport molecules, antibodies (accept any one)

400

Name the process by which a virus attaches to and enters a host cell.

Infection


400

What happens if a cell fails the G1 checkpoint?

Apoptosis 

400

During which phase does the nuclear envelope reform around separated chromosomes?

Telophase

400

What type of biomolecule is starch?

Carbohydrate (polysaccharide)

400

How do lipids function in cells besides energy storage?

Form cell membranes and act as insulation/protection


500

Why are viruses considered nonliving? 

Because they can only reproduce inside a living host cell.

500

What is the purpose of the cell cycle checkpoints?

To make sure the cell is ready to move on to the next phase and prevent errors.

500

What is the final process that physically divides the cytoplasm into two daughter cells?

Cytokinesis 

500

Name a food example rich in nucleic acids.

Any food containing cells, e.g., meat, fish, or plants (all living cells contain DNA/RNA)

500

Why are nucleic acids essential for protein synthesis?

Because DNA holds the instructions and RNA helps assemble proteins.
