Eukaryotic Cell Cycle

What is the Eukaryotic Cell Cycle?

Back

The Eukaryotic Cell Cycle is a series of phases that a eukaryotic cell goes through to grow and divide, including interphase (G1, S, G2) and mitotic phase (M).

Front

Define interphase in the context of the cell cycle.

Back

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

Front

What occurs during the S phase of interphase?

Back

During the S phase, DNA is replicated, resulting in two identical sets of chromosomes for the daughter cells.

Front

What is mitosis?

Back

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

Front

What is the role of checkpoints in the cell cycle?

Back

Checkpoints are regulatory mechanisms that ensure the cell cycle progresses correctly, preventing errors such as DNA damage or incomplete replication.

Front

What is the difference between mitosis and meiosis?

Back

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

Front

Define apoptosis and its significance in the cell cycle.

Back

Apoptosis is programmed cell death that eliminates damaged or unnecessary cells, maintaining tissue health and homeostasis.

Front

What is the significance of crossing over in meiosis?

Back

Crossing over is the exchange of genetic material between homologous chromosomes during meiosis, increasing genetic diversity in gametes.

Front

What is a cancer cell?

Back

A cancer cell is a cell that divides uncontrollably and can invade other tissues, often resulting from mutations in genes that regulate the cell cycle.

Front

Explain the term 'binary fission'.

Back

Binary fission is a form of asexual reproduction in prokaryotes where a single cell divides into two identical daughter cells.
