...Cell Division, Chromosomes, and Inheritance Worksheet Complete all four sections of this worksheet. Section I: Mitosis and Meiosis Part 1: Review the following images on mitosis and meiosis. [pic][pic][pic][pic][pic][pic] [pic] Part 2: Explain the events you observe in the pictures. The top picture is mitosis. The phases listed in order from left to right are: interphase, prophase, prometaphase, metaphase, anaphase, and telophase. During interphase the DNA is replicated and ready for entering of mitosis. During prophase the spindle fibers and centrioles start to move to opposite sides of the cell (2009). This is the longest phase. It is also in this stage that you can begin to see that there are two chromosomes attached together (double helix). In Prometaphase the chromosomes are attached to the spindle fibers and begin to move toward the metaphase plate region (2009). When the chromosomes are lined up it is called metaphase. During anaphase the chromosomes begin to separate into the sister chromatids and start to move toward the opposite poles. Finally in telophase the two sets of identical chromosomes are separated into two new cells. (2009). Web link: Mitosis and the Cell Cycle [Multimedia]. Retrieved from EBOOK COLLECTION: Klug, W.

...managed it and increased the number of copies from 500 to 3500. Poe left the paper due to poor salary in 1836. In 1837 Poe went to New York City again and wrote “The Narrative of Arthur Gordon Pym” but it didn’t support him financially Poe moved to Philadelphia in 1838 and wrote “Ligeia and “The Haunted Palace”. In “Poe: Poetry and Tales” there are a lot of poems written by Poe. But only some of Poe’s great poems shall be considered. In the poem “Spirits of the dead” was mainly intended for his child Virginia Clemm Poe. The poem is about a version of a death, someone who has an earthly bounded spirit. The death of Virginia affected Poe so much that Poe wasn’t acting the same afterwards. Poe wrote in the point of view as a mourner. The line...

...Chapter 14 Mendel and the Gene Idea Lecture Outline Overview • Every day we observe heritable variations (such as brown, green, or blue eyes) among individuals in a population. • These traits are transmitted from parents to offspring. • One possible explanation for heredity is a “blending” hypothesis. ° This hypothesis proposes that genetic material contributed by each parent mixes in a manner analogous to the way blue and yellow paints blend to make green. ° With blending inheritance, a freely mating population will eventually give rise to a uniform population of individuals. ° Everyday observations and the results of breeding experiments tell us that heritable traits do not blend to become uniform. • An alternative model, “particulate” inheritance, proposes that parents pass on discrete heritable units, genes, that retain their separate identities in offspring. ° Genes can be sorted and passed on, generation after generation, in undiluted form. • Modern genetics began in an abbey garden, where a monk named Gregor Mendel documented a particulate mechanism of inheritance. A. Gregor Mendel’s Discoveries 1. Mendel brought an experimental and quantitative approach to genetics. • Mendel discovered the basic principles of heredity by breeding garden peas in carefully planned experiments. • Mendel grew up on a small farm in what is today the Czech Republic. • In 1843, Mendel entered an Augustinian monastery. • He...
