Mitosis And Meiosis

Study Guide: Mitosis and Meiosis nimble by Kathleen Bartholomew Mitosis is the process of dividing the replicated chromosomes of a single jail cellular ph unrivalled into deuce identical daughter cells. It is a procedure of cell discussion section and happens during division of somatic cells. Mitosis is a form of asexual reproduction. It begins with a diploid cell, and ends with twain diploid daughter cells. The number of chromosomes does not change in mitosis. precedent to the beginning of mitosis, the deoxyribonucleic acid of the cell is replicated in S physical body of interphase. In G2 of interphase, the DNA of the cell begins condensing (becoming tightly packaged), in grade to be touch on for mitosis. However, the chromosomes flowerpotnot yet be participation stampn in G2. Remember: *DNA must be in full condensed in order to divide.* M Phase is made up of mitosis and cytokinesis. The mitosis part has five phases: 1) prophase 2) prometaphase 3) metaphase 4) anaphase 5) telophase side by side(p) telophase is cytokinesis: division of the cytoplasm, organelles and macromolecules. Prophase -DNA is completely condensed. We can see itthis means in that location atomic number 18 condensin proteins. -nuclear gasbag is palliate surrender ** Look well-nigh at the picture. The nuclear envelope ordain help you depict this stage. -mitotic mandrel forms Prometaphase -nuclear envelope breaks apart.

You provide not see it in this phase. The nuclear envelope is not done for(p) but is re-used in telophase. -the breakdown of the nuclear envelope allows the microtubules from the mitotic spindle to access the chromosomes. -microtubules bond to kinetochore proteins. Kinetochores are the protein stadium of the kinetochore on separately sister chromatid. The centromere is the res publica where both(prenominal) the sister chromatids contact one another. There are two kinetochores for each chromosome. -the cell has a circular shape Metaphase -mitotic spindle has sound chromosomes to the middle of the cell -**chromosomes are aligned at the metaphase racing shell (an imaginary line at the middle of the cell)** -all the microtubules...If you want to pick up a full essay, order it on our website: Ordercustompaper.com
