12 Questions
During which phase of the cell cycle does DNA replication begin in the nucleus?
Synthesis phase (S phase)
Which phase is marked by the initiation of condensation of chromosomal material?
Prophase
What percentage of the cell cycle duration does interphase typically occupy?
More than 95%
Which phase involves the duplication of centrioles in the cytoplasm?
Synthesis phase (S phase)
At which phase of the cell cycle do cells increase in size but do not replicate their DNA?
Gap1 (G1)
What follows the mitotic (M) phase in the cell cycle?
Cytokinesis
During prophase, which cellular components are not visible in the cell under a microscope?
Golgi complexes, endoplasmic reticulum, nucleolus, and the nuclear envelope
What is the main role of centrioles during mitosis?
Moving towards opposite poles of the cell
What happens to the chromatids during anaphase of mitosis?
They are pulled apart and move to opposite ends of the cell
What defines the completion of cytokinesis?
Division of nuclei, cytoplasm, organelles, and cell membrane into two cells
What characterizes telophase of mitosis?
Chromosomes decondense and nuclear envelope forms
In metaphase of mitosis, where do chromosomes line up?
In the middle of the cell (the equator)
Explore the fundamental concepts of the cell cycle and cell division in all living organisms. Learn about the phases of the cell cycle, including interphase, mitotic phase, and cytokinesis. Understand how the cell cycle contributes to the development and renewal of different organisms and organs.
