Cycle and Cancer Worksheet 1. In which phase of mitosis do each of the following occur: a. Centromeres split and chromosomes move toward opposite sides of the cell occur during the anaphase. b. Chromatin coils to form visible chromosomes occur in the prophase. c. The nuclear membrane disappears occur in the prophase. d. Sister chromatids line up in the center of the cell occur in the metaphase. 2. In which phases of mitosis are sister chromatids visible‚ and attached to each other

Name the phase of mitosis that follows anaphase. telephase 16. Name this phase in which a nucleus is visible and the DNA is spread out as chromatin. interphase 17. Name the phase of mitosis in which chromatid arms separate and move to opposite ends of the cell. anaphase 18. TRUE or FALSE The sister chromatids on a chromosome are

number: a) is doubled b) is reduced c) remains the same d) becomes diploid e) becomes tetraploid 5. Prophase I of meiosis (is‚ is not) similar to prophase of mitosis. 6. The first anaphase of meiosis differs from anaphase of mitosis in that centromeres (do‚ do not) divide. 7. Oogenesis ultimately gives rise to (one ovum‚ four ova) with the (haploid‚ diploid) number of chromosomes. 8. A spermatazoan is a (gamete‚ zygote)‚ and

about 10 hours S phase usually takes 5-6 hours to complete G2 phase usually lasts 2-3 hours Mitosis takes about 2 hours The Cell Cycle takes about 18-20 hours. Mitosis 1. Interphase- Chromosomes are copied Chromosomes appear as threadlike coils (chromatin) at the start‚ but each chromosome and its copy (sister chromosome) change to sistr chromatids at the end of this phase. 2. Prophase- Mitosis begins (cell begins to divide) Centrioles (or poles) appear and begin to move to the opposite

uncontrolled division of unusual cells in a part of the body. It is a disease of mitosis‚ which begins when one cell is transformed from a normal cell to a cancerous cell. Mitosis is a type of cell division which has 6 steps (Interphase‚ Prophase‚ Metaphase‚ Anaphase‚ Telophase‚ and Cytokinesis) that result in two daughter cells that are clones of the parent. Cancerous cells do not abide by the normal instructions of mitosis. Instead‚ the cells speed through many of these stages and continue to divide

what is the connection between volume of a cell and how quickly the cell uses up oxygen and food and produces wastes? What happens to surface area and volume as a cell gets larger? Describe the two main reasons why cell size is limited Compare mitosis and cytokinesis Adding more cells The more surface area‚ the more quickly the cell can exchange water‚ oxygen‚ food and wastes The greater the volume of a cell‚ the more quickly the cell uses up oxygen and food and produces wastes As the cell

Interphase is the first stage‚ and it’s composed of G1 (contents of the cell are duplicated sans the chromosomes)‚ S (chromosomal duplication)‚ and G2 (checkpoints) phase. After interphase‚ there is the mitotic phase. The mitotic phase is composed of mitosis (division) and then cytokinesis (division of cytoplasm=2 daughter cells). The cell cycle ultimately produces two daughter cells. These processes allow the (complete) genetic material present in a cell/organism to be passed on to the daughter cells

growth of the root and is one of the regions in the plant where cells are actively dividing and growing. Because of this‚ the root tip is an excellent system in which to observe the entire cell cycle‚ including the processes of nuclear division (mitosis) and cell division (cytokinesis). You will be submitting a lab report as the assignment for this lesson. Be sure to read the instructions before completing the virtual lab activity and your lab report. Refer to the lab rubric before you submit your

time a nerve impulse is passed down the axon‚ and is important as it allows the action potential to be passed along the axon. Examples of biological cycles at a cellular level include the cell cycle‚ mitosis and meiosis. Most eukaryotic cells follow this process‚ which includes a growth stage‚ mitosis or nuclear division‚ and cytokinesis. Throughout interphase‚ the cell undergoes growth and metabolic activities. Interphase can be further broken down into G1 (where normal cell functions occur‚ as
