Second Marking Period Review

Front

What is the last phase of the cell cycle where the cytoplasm is divided?

Back

Cytokinesis

Front

Which biomolecule is responsible for catalyzing and speeding up chemical reactions?

Back

Proteins

Front

How many chromosomes does a cell have after the S phase if it starts with 12 chromosomes?

Back

24

Front

What phase of mitosis is characterized by the chromosomes lining up in the middle of the cell?

Back

Metaphase

Front

Why is interphase considered the longest phase of the cell cycle?

Back

DNA replication and growth of the cell happen here.

Front

What is the primary function of proteins in biological systems?

Back

To catalyze biochemical reactions and perform various functions in the cell.

Front

What occurs during prophase of mitosis?

Back

Chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down.

Front

What is the role of lipids in biological systems?

Back

Lipids serve as structural components of cell membranes and as energy storage molecules.

Front

What happens during anaphase of mitosis?

Back

Sister chromatids are pulled apart to opposite poles of the cell.

Front

What is the significance of the S phase in the cell cycle?

Back

The S phase is when DNA replication occurs, resulting in two copies of each chromosome.
