Front

Where is DNA usually found in a cell?

Back

DNA is usually found in the nucleus of a cell, which houses the genetic material.

Front

In double-stranded DNA, what is the relationship between Adenine and Thymine?

Back

In a molecule of double-stranded DNA, the amount of Adenine is always equal to the amount of Thymine.

Front

What are the four main types of macromolecules?

Back

The four main types of macromolecules are carbohydrates, lipids, proteins, and nucleic acids.

Front

What is the function of carbohydrates in living organisms?

Back

Carbohydrates provide short-term energy and serve as structural components in cells.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts are organelles that conduct photosynthesis, converting light energy into glucose.

Front

What is the basic unit of life?

Back

The cell is the basic unit of life, serving as the smallest structural and functional unit of an organism.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and organelles.
