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 carrying out essential processes such as metabolism and DNA replication.

Why do cells spend most of their time in interphase?

Back

Cells spend most of their time in interphase to grow and carry out essential processes such as metabolism and DNA replication.

During which phase of the cell cycle does DNA replication occur?

Back

DNA replication occurs during the S phase of the cell cycle.

Front

What is the S phase?

Back

The S phase is the part of the cell cycle where DNA is replicated, leading to the formation of two identical sets of chromosomes.

What is a defining property of cancer cells?

Back

Cancer cells undergo unregulated cell division, leading to uncontrolled growth.

Front

How do normal cells differ from cancer cells in terms of division?

Back

Normal cells stop dividing after reaching a certain size, while cancer cells continue to divide uncontrollably.

Front

What is DNA replication?

Back

DNA replication is the process by which a cell makes an identical copy of its DNA before cell division.

Front

What role does DNA polymerase play in DNA replication?

Back

DNA polymerase is an enzyme that matches nucleotides to form new DNA strands during replication.

Front

What is the result of DNA replication?

Back

The result of DNA replication is the formation of two identical double helices of DNA.

Front

How can environmental factors influence gene expression?

Back

Environmental factors can influence gene expression by affecting the transcription of DNA to mRNA, which is then translated into proteins.
