Mitosis in a Nutshell
•The stages of the cell circuit can be broken down into six stages: oInterphase, Prophase, Metaphase, Anaphase, Telophase
•Is the " resting" or non-mitotic portion of the cell routine. •It is definitely comprised of G1, S, and G2 stages of the cell cycle. •DNA is replicated during the S i9000 phase of Interphase
Prophase - the first level of mitosis.
•The chromosomes condense and be visible
•The centrioles form and move toward contrary ends from the cell (" the poles" ) •The nuclear membrane layer dissolves
•The mitotic spindle forms (from the centrioles in animal cells) •Spindle fibers by each centriole attach to every single sister chromatid at the kinetochore Compare Prophase to the Prophase I and to the Prophase II periods of mitosis.
•The Centrioles full their immigration to the poles
•The chromosomes line up in the center of the cellular (" the equator" ) Compare Metaphase to the Metaphase I and to the Metaphase II periods of mitosis. Anaphase
•Spindles attached to kinetochores begin to cut short.
•This applies a push on the sister chromatids that pulls all of them apart. •Spindle fibers carry on and shorten, yanking chromatids to opposite poles. •This makes certain that each girl cell gets identical pieces of chromosomes Compare Anaphase to the Anaphase I and also to the Anaphase II stages of mitosis.
•The chromosomes decondense
•The elemental envelope forms
•Cytokinesis extends to completion, creating two girl cells Evaluate Telophase to the Telophase I actually and to the Telophase II stages of mitosis.
Easy muscle cellular material are spindle shaped and uninucleate. (B). Functions: unconscious movement -- i. electronic. churning of food, movements of urine from the kidney to the urinary, partuition SKELETAL MUSCLE
Bone muscle skin cells run the entire length of a muscle. Series A show the width of 1 cell (fiber). Note the striations characteristics of this muscle tissue type. These types of cells happen to be multicellular,...
