Cell Cycle & DNA Replication

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell prepares for division. It includes growth (G1), DNA replication (S), and preparation for mitosis (G2).

Front

What happens during the S phase of the cell cycle?

Back

During the S phase (Synthesis phase), DNA is replicated, resulting in two identical sets of chromosomes.

Front

What is cytokinesis?

Back

Cytokinesis is the process that follows mitosis, where the cytoplasm and organelles are divided between the two new daughter cells.

Front

What are stem cells?

Back

Stem cells are undifferentiated cells that have the potential to become specialized cells when they receive specific chemical signals.

Front

What is the role of the centromere?

Back

The centromere is the region of a chromosome where the two sister chromatids are joined together and where the spindle fibers attach during cell division.

Front

What occurs during Gap 1 (G1) phase?

Back

During Gap 1 phase, the cell grows, synthesizes proteins, and obtains nutrients in preparation for DNA replication.

Front

What is the difference between mitosis and cytokinesis?

Back

Mitosis is the process of nuclear division, while cytokinesis is the division of the cytoplasm and organelles into two daughter cells.

Front

What is the significance of the G2 phase?

Back

The G2 phase is the final stage of interphase where the cell continues to grow and prepares for mitosis by producing necessary proteins and organelles.

Front

What is the purpose of DNA replication?

Back

The purpose of DNA replication is to ensure that each daughter cell receives an identical set of chromosomes during cell division.

Front

What is the definition of chromatin?

Back

Chromatin is the complex of DNA and proteins found in the nucleus of eukaryotic cells, which condenses to form chromosomes during cell division.
