Class instructions

​Use journal notes and packet to complete
Quizizz Lesson.

Review the content in the note packet and learn the phases of Mitosis. Be prepared to summarize chapter tomorrow.

​The following chart will serve as a study guide.

Multiple Choice

What is the difference between chromatids and chromatins?

• Chromatids are a type of protein; chromatin is a type of RNA.
• Chromatids are found only in prokaryotic cells; chromatin is found in eukaryotic cells.
• Chromatids are duplicated chromosomes; chromatin are loose DNA and proteins.

• Chromatids are the relaxed form of DNA; chromatin is the duplicated chromosome.

Multiple Choice

What is the purpose of a telomere?

• The purpose of a telomere is to protect chromosome ends and handle replication.

• The purpose of a telomere is to facilitate protein synthesis and growth.

• The purpose of a telomere is to act as a binding site for RNA and DNA.

• The purpose of a telomere is to provide energy to the cell and help it grow.

Multiple Choice

What is the purpose of the cell cycle?

• The purpose of the cell cycle is to enhance cellular respiration and energy production.

• The purpose of the cell cycle is to facilitate protein synthesis and enzyme activation.

• The purpose of the cell cycle is to promote cellular aging and apoptosis.

• The purpose of the cell cycle is to regulate cell growth, DNA replication, and cell division.

Match

Match the following phases of the cell cycle with their description.

• G1 phase

• S phase

• G2 phase

• M phase

Cell growth and preparation for DNA replication

DNA synthesis and replication

Cell growth and preparation for mitosis

Cell division

• Cell growth and preparation for DNA replication

• DNA synthesis and replication

• Cell growth and preparation for mitosis

• Cell division

Multiple Choice

How is prophase different from interphase?

• Prophase occurs after interphase and does not involve any chromosomal changes.
• Interphase is characterized by chromosome separation, while prophase involves DNA synthesis.
• Prophase is the phase where cells divide, while interphase is when they grow and divide into a new cell

• Prophase make the chromosomes visible and spindle formation; interphase is the prepares a new cell with DNA replication.

Reorder

Multiple Choice

How can you identify the telophase of mitosis?

• Telophase occurs when the spindle fibers are fully formed.
• Telophase reforms the nuclear envelope and the de-condensation of chromosomes.

• Telophase is marked by the alignment of chromosomes at the cell equator.
• Telophase is characterized by the separation of sister chromatids.

Multiple Choice

Why do the chromosomes line up in the middle during metaphase?

• Chromosomes line up in the middle to prepare for DNA replication.
• Chromosomes line up in the middle to ensure they divide equally.

• Chromosomes align in the center to increase their size.
• Chromosomes gather in the middle to signal the end of cell division.

Multiple Choice

How is cytokinesis shown in the cell?

• Cytokinesis occurs only in animal cells and not plant cells.

• Cytokinesis is the same as mitosis in the cell.

• Cytokinesis is shown by the formation of a divide in the cell.

• Cytokinesis involves the splitting of the nucleus in the cell.
