Biology Semester 1 Review

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, essential for growth and repair in organisms.

Front

Why is mitosis important in organisms?

Back

Mitosis is important because it creates genetically identical daughter cells for growth and repair.

Front

What is cell differentiation?

Back

Cell differentiation is the process by which cells become specialized in structure and function based on gene expression.

Front

What role does RNA play in protein synthesis?

Back

RNA transfers genetic instructions from DNA to the ribosome, where proteins are synthesized.

Front

What is the correct order of biological organization?

Back

The correct order is: Macromolecule → Cell → Tissue → Organ → Organ System → Organism.

Front

What is the best definition of differentiation?

Back

Differentiation is the process by which cells specialize for specific functions.

Front

What is a macromolecule?

Back

A macromolecule is a large complex molecule, such as proteins, nucleic acids, carbohydrates, and lipids, essential for life.

Front

What is the function of ribosomes?

Back

Ribosomes are cellular structures that synthesize proteins by translating messenger RNA (mRNA).

Front

What is the difference between DNA and RNA?

Back

DNA stores genetic information, while RNA transfers genetic instructions from DNA to the ribosome for protein synthesis.

Front

What is the significance of gene expression?

Back

Gene expression determines how genes are turned on or off, influencing cell function and specialization.
