What is cell differentiation?

Back

Cell differentiation is the process by which a less specialized cell becomes a more specialized cell type, allowing for the formation of different tissues and organs in an organism.

Front

What is interphase in the cell cycle?

Back

Interphase is the phase of the cell cycle where the cell spends most of its time, growing and performing essential functions such as metabolism and DNA replication before mitosis.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, allowing for growth and repair in multicellular organisms.

Front

What are cancer cells?

Back

Cancer cells are abnormal cells that divide uncontrollably and can invade other tissues, often leading to tumors and other health issues.

Front

What is gene expression?

Back

Gene expression is the process by which information from a gene is used to synthesize a functional gene product, usually proteins, which perform various functions in the cell.

Front

What is the S phase of the cell cycle?

Back

The S phase (synthesis phase) is the part of interphase where DNA is replicated, ensuring that each daughter cell receives an identical set of chromosomes.

Front

What role do environmental factors play in gene activation?

Back

Environmental factors can influence gene activation by affecting the transcription of DNA to mRNA, which is necessary for protein synthesis.

Front

What is the significance of the G1 phase?

Back

The G1 phase is the first phase of interphase where the cell grows and prepares for DNA replication, ensuring it has the necessary resources for the next phase.

Front

What happens during the G2 phase?

Back

During the G2 phase, the cell continues to grow and prepares for mitosis by producing proteins and organelles needed for cell division.

Front

What is apoptosis?

Back

Apoptosis is the process of programmed cell death that occurs in multicellular organisms, allowing for the removal of damaged or unnecessary cells.
