Student Exploration: Cell Division Vocabulary: cell division‚ centriole‚ centromere‚ chromatid‚ chromatin‚ chromosome‚ cytokinesis‚ DNA‚ interphase‚ mitosis Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. Cells reproduce by splitting in half‚ a process called cell division. What do cells need to do between divisions to make sure that they don’t just get smaller and smaller? The cell needs to go through a phase after cell division. 2. The genetic information of

periods: interphase‚ the mitotic phase‚ and cytokinesis. During interphase‚ the cell grows‚ accumulating nutrients needed for mitosis‚ preparing it for cell division and duplicating its DNA. During the mitotic phase‚ the cell splits itself into two distinct daughter cells. During the final stage‚ cytokinesis‚ the new cell is completely divided. To ensure the proper division of the cell‚ there are control mechanisms known as cell cycle checkpoints. The cell cycle starts with interphase. This is

stage involved in the eukaryotic cell cycle is called interphase. Interphase is the period between divisions that has 3 separate phases. The first phase in interphase is G1‚ where G stands for gap‚ and in this phase the growth of cell parts occurs and materials needed for transcription‚ translation and DNA replication are made and if given the signal‚ preparation for S-phase occurs in this phase (Mrs. Weiland‚ 11/16/15). The second phase of interphase is S-Phase‚ or DNA synthesis‚ which is where DNA replication

(I = 1‚ C = 2) 2) During interphase‚ what event must occur for the cell capable of undergoing future divisions? (A = 1‚ C = 2) 3) Using a dictionary (or your electronic devices)‚ look up the meaning of the prefixes used in the stages of mitosis: pro-‚ meta-

Isolation and Characterization of Complex Lipids Shea Kathleen Guinto‚ Peter Julius Dale Inocando*‚ SooHyun Jung‚ Jurilla Camille Louise Department of Biology‚ University of Santo Tomas‚ Manila‚ Philippines Abstract In this experiment an egg yolk will serve as the sample to isolate lipids and separate them into two classes which is the phosphorylated lipid and the non-phosphorylated lipid. The isolated lipids are then characterized through a series of color chemical tests along with the given

counted to figure out in which phase the cell remains the most. If interphase is the stage in which the cell grows and prepares for cell division then the number of cells undergoing interphase will be the most. After cells were counted it came out that indeed the number of cells in interphase is the most followed by prophase‚ metaphase=anaphase and telophase. This makes us come to the conclusion that the longest phase for a cell is interphase in which the cell grows and gets ready to divide. The second

| CELLULAR DIVISION AND REPLICATION WITHIN MITOSIS AND MEIOSIS ABSTRACT The processes of mitosis and meiosis were examined along with their frequency as well as each of the different steps and their time duration. It was found that the interphase stage of both mitosis and meiosis was the longest of all the stages as this was where most of the ‘action’ was happening such as cell growth and duplication of all cell organelles and chromosome replication also. It was also found that mitosis and

understand the process of crossing over. This lab also helps students understand the similarities along with differences between mitosis and meiosis. Hypothesis: I predict that interphase will be the longest phase because many events such as a cell growth and chromosome replication occur during interphase‚ which I believe‚ would be a long process. I also think that the frequency of crossing over is affected by the distance between genes. I believe that mitosis and meiosis have very clear

cell reproduces‚ it must replicate all its chromosomes to pass its genes to the next generation of cells. The cell cycle consists of two major periods: interphase‚ when a cell is not dividing‚ and the mitotic phase‚ when a cell is dividing. During interphase the cell replicates its DNA. Interphase is a stage of high metabolic activity. Interphase has three phases: G1‚ S‚ and G2. The G1 phase is the interval between the mitotic phase and the S phase. During this phase the cell is active. It replicates
