Cell Cycle & DNA Synthesis

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell grows, carries out normal functions, and prepares for division. It consists of three stages: G1, S, and G2.

Front

What happens during the G1 phase of interphase?

Back

During the G1 phase, the cell grows and synthesizes proteins necessary for DNA replication.

Front

What occurs during the S phase of interphase?

Back

During the S phase, DNA replication takes place, resulting in two identical sets of chromosomes.

Front

What is the G2 phase?

Back

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

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells.

Front

What is cytokinesis?

Back

Cytokinesis is the process that follows mitosis, where the cytoplasm of a parental cell divides into two daughter cells.

Front

What is chromatin?

Back

Chromatin is a complex of DNA and proteins found in the nucleus of eukaryotic cells, existing in a relaxed form during interphase.

Front

What is the role of DNA polymerase?

Back

DNA polymerase is an enzyme that synthesizes new DNA strands by adding nucleotides to a growing chain during DNA replication.

Front

What is the difference between chromatin and chromosomes?

Back

Chromatin is the relaxed form of DNA, while chromosomes are tightly packed structures of DNA that are visible during cell division.

Front

What is the function of helicase?

Back

Helicase is an enzyme that unwinds the DNA double helix during DNA replication, allowing the strands to be copied.
