Mitosis
Cards (32)
- It is a series of physiologic events in eukaryotic cells that ultimately leads to growth and cell division?
- The resting stage of the cell is known as?
- It is where the cell becomes metabolically active in preparation for DNA replication. The cell undergoes physical growth, duplicates its organelles and cytosolic components and starts replicating its centromeres for about 8-10 hours?
- This is where the DNA content of the cell is duplicated and may last for 6-8 hours. The DNA content is duplicated so that when it divides into two daughter cells later, each one will contain the same number of chromosomes?
- It is where the cell continues its growth, synthesizes proteins and enzymes needed for cell division, and completes the replication of it’s centromeres for about 4-5 hours?
- It is the active portion of the cell cycle that includes the G1, S, and G2 phases, where the cell grows, replicates its DNA, and prepares for mitosis, respectively?
- Which the cell divides into two daughter cells with equal DNA content and is the shortest phase at up to 2 hours?
- The cell cycle is a highly regulated process with ___ and ___ as major control molecules which serve as checkpoints between each phases?
- It is the cell division process wherein the daughter cells will have the same chromosome number as their parent cell?
- Mitosis is also called?
- MITOSIS is for body cells because body cells are needed to be ___?
- Mitosis can be divided into four major parts?
- threadlike structures made of protein and a single molecule of DNA that serve to carry the genomic information from cell to cell?
- one of the two identical halves of a chromosome?
- a protein structure that divides the genetic material in a cell?
- structure in a chromosome that holds together the two chromatids?
- a double layer that encloses or envelops the cell's nucleus, where the chromosomes reside?
- An area inside the nucleus of a cell that is made up of RNA and proteins and is where ribosomes are made?
- Think of “Pro” for before, a reminder that it is the first phase?
- Two kinds of Prophase?
- The chromatin coils to form long thin threads and start forming chromosomes. The nuclear membrane starts to disappear along the nucleolus. The spindle fibers that are made up of microtubules also start to form?
- During this, the spindle fibers start to capture the chromosomes by attachment to the kinetochore, the disc shaped protein complex in the centromere, which is essential for the movement of the chromosomes later on?
- Late Prophase is also called?
- Think of M for middle. In this phase, the chromosomes align to the middle of the cell . At this point, the nuclear membrane has completely dissolved?
- Animal cells undergo ___, which is characterized by the formation of star-shaped complex of microtubules emanating from the centrioles?
- formation of star-shaped complex of microtubules emanating from the centrioles called?
- Plant cells, however, undergo ___, which is different from amphiastral mitosis because it does not have asters from the lack of centrioles?
- Think of A for away. This is characterized by the separation of the sister chromatids and their movement towards the opposite poles of the cell due to the spindle fiber contractions?
- This is the last stage of mitosis. It is when the chromosomes have reached the opposite poles and uncoil, the spindle fibers disappear and the nuclear membrane reform?
- Once all of the phases of mitosis have finished, the cell divides into two daughter cells through this process?
- In animal cells cytokinesis occurs by having the cell membrane turn inside out or?
- cytokinesis occurs in plant cells by the formation of ___?
