Comparing Mitosis and Meiosis Observe: 1. Organisms have a number of chromosomes in each of their body or somatic cells that is unique for that organism. This is called their diploid or 2n number. 2. Cells go through a cell cycle‚ whereby‚ much of the cycle does not include division‚ but at the end of this interphase in their cycle‚ they go through mitosis. 3. Cells replicate their DNA in the S phase of the cell cycle. 4. In the process of mitosis‚ cells replicate their DNA in the nucleus‚ form

nuclear material in which each new nucleus obtains the same number of chromosomes and the same nuclear code as the original nucleus is call mitosis. Mitosis occurs in four phases. Interphase occurs between mitosis. Interphase: Cell contains easily seen nucleus and nucleolus- chromosomes appear as fine dots within nucleus Mitosis: 4 steps Prophase – cell nucleus enlarged –nucleolus no longer visible- chromosomes appear as short strands within nucleus. Metaphase – chromosomes long and thin strands

Complete the following questions and submit via Blackboard 1. List two events which occur during prophase of mitosis: 1. An aster is formed by fibers radiating from the centrioles of the cell. 2. Chromosomes are formed when the chromatin threads coil and then condense‚ and these chromosomes are two identical chromatids bound together by a centromere. 2. What is the main occurrence involving the chromosomes during

Cell Division Why must cells divide? To start it off‚ cells can’t keep growing forever‚ so when they reach a certain size they will have to divide. Cells divide for four important reasons; reproduction‚ growth‚ repair‚ and replacement of damaged or worn out cells. Most cells divide at least once during their life cycle and some divide divide dozens of time times before they die. There are three types of cell division. They are binary fission‚ mitosis‚ and meiosis. When cell division is

Cell Reproduction Dr. Susan Kennedy Introduction to Biology January 28‚ 2012 Introduction Cellular reproduction is the process by which cells duplicate their contents and then divide to yield two cells with similar‚ if not duplicate contents. Life as we know it depends on the ability of cells to store‚ retrieve and translate the genetic instructions required to make and maintain a living organism. In this assignment‚ I will discuss two different types of cell reproduction

straight sides. E.g. The shape ABCD shown here is a quadrilateral. A line segment drawn from one vertex of a quadrilateral to the opposite vertex is called a diagonal of the quadrilateral. AC is a diagonal of quadrilateral ABCD‚ so is BD. TYPES & PROPERTIES OF QUADRILATERALS There are seven types of quadrilaterals that can be divided into two groups: parallelograms and other quadrilaterals. 1. Parallelograms Quadrilaterals are called parallelograms if both pairs of opposite sides

PRACTICAL 1: HUMAN KARYOTYPING LAB INTRODUCTION The complete set of chromosomes in the body cell of a species is known as karyotype. Karyotype is a test to identify and evaluate the size‚ shape‚ and number of chromosomes in a sample of body cells. Any abnormalities such as extra‚ missing‚ or abnormal positions of chromosome pieces can cause problems with a person growth‚ development and body functions. Karyotype can be used to determine whether the chromosomes of an adult have an abnormality

In the Mitosis lab an onion root was observed under a microscope to observe whether or not cell division takes place. Also‚ whether cells replicate in order for it to reproduce. By observing the onion root under the microscope it allows many layers to be looked at through each cell division. The goal of Mitosis is the replication of cells to produce multiple like cells. The steps involved in Mitosis are what is known as the PMAT stages‚ which are the following: Prophase‚ Metaphase‚ Anaphase and Telephase
