2024 Fall Semester Biology Exam Review

Front

What are tumors?

Back

Tumors are abnormal tissue masses formed by the uncontrolled multiplication of cancerous cells.

Front

What stage of mitosis involves the separation of chromatids?

Back

Anaphase is the stage of mitosis where spindle fibers pull the chromatids to opposite sides of the cell.

Front

What is meiosis?

Back

Meiosis is the form of cell division in humans that halves the number of chromosomes to produce gametes.

Front

What does the 'M' in the cell cycle model stand for?

Back

The 'M' stands for Mitosis, which is the stage of cell division.

Front

In which phase of the cell cycle does DNA double?

Back

DNA doubles during the S phase of the cell cycle.

Front

What is the purpose of mitosis?

Back

Mitosis is the process of cell division that results in two identical daughter cells, maintaining the same chromosome number.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical cells, while meiosis produces four genetically diverse gametes with half the chromosome number.

Front

What are spindle fibers?

Back

Spindle fibers are structures that help separate chromosomes during cell division by connecting to the kinetochores.

Front

What is cytokinesis?

Back

Cytokinesis is the process that follows mitosis, where the cytoplasm divides, resulting in two separate cells.

Front

What happens during prophase?

Back

During prophase, chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down.
