Checkpoint 17 Review: Understanding DNA and Cell Cycle

Front

Do all of the cells in your body contain the same DNA?

Back

Yes, all cells contain the same DNA because they originate from a single fertilized egg.

Front

What are chromatids?

Back

Chromatids are the two identical halves of a duplicated chromosome, which are joined together by a centromere.

Front

What phase of the cell cycle is characterized by the division of the cytoplasm?

Back

Cytokinesis is the phase of the cell cycle where the cytoplasm divides, resulting in two separate cells.

Front

What is the correct sequence of the cell cycle?

Back

Interphase, Mitosis, Cytokinesis.

Front

What are chromosomes?

Back

Chromosomes are structures within cells that contain DNA and genetic information.

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell prepares for division, including DNA replication.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What is the role of centromeres?

Back

Centromeres are the regions of a chromosome where the two sister chromatids are joined together.

Front

What is the difference between mitosis and meiosis?

Back

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

Front

What is chromatin?

Back

Chromatin is the material that makes up chromosomes, consisting of DNA and proteins.
