great place to observe mitotic cell divisions. Through the observation and comparison of different regions of the root tip‚ the duration of mitotic stages and mitotic indexes are determined for the various divisions of the root tip. Methods Each group used a compound microscope to analyze the different sections of the onion root tip. The root tip was visually divided into four sections sized by the field of view through the microscope. Section I‚ the section nearest the tip‚ was subdivided

Mitosis is a cellular process that replicates chromosomes and produces two identical nuclei in preparation for cell division‚ from the original cell two cells are derived‚ each of which possesses the same genetic material. Mitosis has five phases: interphase‚ prophase‚ metaphase‚ anaphase and telophase. Interphase The DNA duplicates during interphase to prepare for mitosis. Chromosomes are not clearly discerned in the nucleus. Prophase Chromatin in the nucleus begins to condense and becomes visible

and gets rid of waste. It grows and reproduces‚ or creates one of its own kind. (Garrod 36) Most cells reproduce by dividing‚ so that there are two cells where there once was one. (Akkas 78) Every living thing is made up of one or more cells‚ and each of these cells was produced by an already existing cell. New cells are formed by dividing‚ so that there are two cells were there once was one. One-celled plants and animals begin and complete their lives as single cells. (Kemp 12) Human beings and

Mitosis Mitosis is the process of a cell dividing. A parent cell divides to create two identical daughter cells‚ which are exact replicas of the original parent cell. DNA is replicated‚ and each daughter cell receives one copy of the original DNA and the cell goes through a process consisting of 4 steps called mitosis. Interphase‚ which isn’t part of mitosis‚ is the "stage" when the cell is not in the process of dividing‚ but DNA is being replicated. Interphase itself has its three phases‚ G1 phase

Mitosis vs. Meiosis Mitosis and meiosis are very similar processes but they are also quite different. In both of these dna is replicated before the prophase. The sister chromatids are both separated in anaphase of these processes‚ however in meiosis it is in the anaphase 2 stage. Finally both stages have microtubules to separate chromosomes and both begin in the prophase and end in telophase. There are also several key differences. Mitosis occurs during growth of organism or to repair tissue
