Cell Division

Front

What is the phase of mitosis where spindle fibers pull chromosomes apart?

Back

Anaphase.

Front

How does the cell cycle contribute to the life cycle of an organism, such as a frog?

Back

The cell cycle allows organisms to grow, develop, and reproduce.

Front

What is the genetic basis of coat-color variation in Texas Longhorn cattle?

Back

Nucleotide gene sequence differences.

Front

What is the significance of base pairing in DNA?

Back

Base pairs must be correctly paired for proper DNA function.

Front

What role do oncogenes play in cancer development?

Back

Oncogenes lead to unregulated cell division, contributing to tumor formation.

Front

What are the main stages of the cell cycle?

Back

Interphase, mitosis, and cytokinesis.

Front

What occurs during interphase?

Back

The cell grows, duplicates its DNA, and prepares for mitosis.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis produces four genetically diverse gametes.

Front

What is the function of spindle fibers during mitosis?

Back

Spindle fibers help separate chromosomes and pull them to opposite poles of the cell.

Front

What is a tumor?

Back

A tumor is an abnormal mass of tissue that forms when cells divide uncontrollably.
