The Cell Cycle: A Comprehensive Guide to Mitosis, Meiosis, and Cell Regulation, Exams of Microbiology

A detailed overview of the cell cycle, including its various stages (interphase, prophase, metaphase, anaphase, telophase, and cytokinesis), key components (chromosomes, chromatids, centrioles, spindle fibers), and regulatory mechanisms (cyclins and checkpoints). it also explores the significance of mitosis, the consequences of uncontrolled cell division (cancer), and the process of programmed cell death (apoptosis). The resource is valuable for students learning about cell biology and genetics.

The Cell Cycle, Cell Cycle Latest Update

100% Correct

cytokinesis ✔✔Complete cytoplasmic separation of the 2 new cells resulting from mitosis.

mitosis ✔✔The process of NUCLEAR division

interphase ✔✔Period of time where a cell carries out cell processes and replicates DNA prior to cell division

prophase ✔✔Chromatin condenses into chromosomes

metaphase ✔✔Chromosomes line up in the middle of the cell

anaphase ✔✔Sister chromatids separate

telophase ✔✔new nuclei begin to reform, chromatids relax

chromatid ✔✔Each half of the chromosome

chromosome ✔✔condensed chromatin; contains DNA that carries genetic information

centromere ✔✔attachment site of sister chromatids

cell cycle ✔✔An ordered sequence of events in the life of a eukaryotic cell; process of growth and division.

G1 phase ✔✔interphase stage of cell cycle where cell grows and carries out metabolic processes

G2 phase ✔✔interphase stage prepares to divide by copying organelles and producing proteins necessary for division

S phase ✔✔interphase stage of cell cycle where cell replicates DNA

stage of the cell cycle where the nucleus divides ✔✔mitosis

Prophase diagram ✔✔Identify the stage using the diagram.

Metaphase diagram ✔✔Identify the stage using the diagram.

Anaphase diagram ✔✔Identify the stage using the diagram.

Telophase diagram ✔✔Identify the stage using the diagram.

Cytokinesis diagram ✔✔Identify the stage using the diagram.

Centriole ✔✔organelle of animal cell that aids in cell division

Spindle fiber ✔✔microtubule threads that emerge from centrioles, attach to chromosomes to pull them apart during mitosis

reasons for mitosis ✔✔divides cells that are too large, replaces damaged/dying cells, allows for growth

Cleavage furrow ✔✔a pinching of the cell membrane that begins to form in telophase

cell plate ✔✔method of plant cell division; formation of a new cell wall instead of cleavage furrow

Cyclins and Checkpoints ✔✔Regulation system for the cell cycle

Cyclins ✔✔Signal each stage of the cell cycle to begin

Carcinogens ✔✔cancer causing factors (tobacco, chemicals, UV radiation)

steps of mitosis ✔✔PMAT

steps of interphase ✔✔G1, S, G

apoptosis ✔✔programmed cell death

end product of the cell cycle ✔✔2 identical daughter cells
