Bio-111 Laboratory #8 Mitosis and Meiosis 17 November 2010 Part1-Questions: a) Explain mitosis Mitosis is a process of asexual reproduction in eukaryotic cells. This process is divided into five stages: prophase‚ metaphase‚ anaphase‚ telophase and cytokinesis. A diploid cell duplicates its genetic information. Therefore the two diploid daughter cells will receive an exact copy of the genetic material. Explain meiosis Meiosis is a two round cell division process where a diploid cell divides

Process of Mitosis Mitosis is the term used to describe cell division for replication. The product at the end of mitosis is two daughter cells both genetically identical to the original (parent) cell. This process (mitosis) is used for growth and repair within an organism (and also for asexual reproduction). There are five main stages to mitosis‚ called Interphase‚ Prophase‚ Metaphase‚ Anaphase and Telophase. Although the process has been divided up into these stages the process of mitosis is actually

1 – Mitosis and Meiosis 1. A certain species has three pairs of chromosomes: an acrocentric pair‚ a metacentric pair‚ and a telocentric pair. Draw a cell of this species as it would appear in metaphase of mitosis. (BAP 2.18) 2. A cell in G1 of interphase has 12 chromosomes. How many chromosomes and DNA molecules will be found per cell when this original cell progresses to the following stages? (BAP 2.20) a) G2 of interphase b) Metaphase I of meiosis c) Prophase of mitosis d) Anaphase I of meiosis

Ensure that your name/ ID no. and sample number are recorded. The report should be written according to the sample problem provided in the handout. Question: Seeds of the F1 generation derived from a cross between two different yellow-seeded varieties of corn were collected as Sample F1. The F1 plants were selfed

Lab Report 3 In this lab‚ we will take a trip to the planetarium lab and will learn about Right ascension and declination‚ and altitude and zenith. After looking at the different points shown‚ we will log the altitude and zenith in the chart in our lab manual. Now we will look at the same points and label the right ascension and declination. Then we will learn about the easiest way to locate the star Polaris. As we started the first program‚ we answered a few questions to make sure we knew

This lab report will be detailing the steps taken and the results discovered when using spectrophotometry to determine the percentage of copper in a copper-clad penny and the thicknes of the copper layer on the copper-clad penny. After 1982‚ copper coating has been used in the creation of the penny because the cost of pure copper has increase to the point that the amount needed t omake a penny cost far more than the actual value of the penny. This lab allowed us to see just how much copper coating

ecology‚ social organization and sensory abilities of an animal (J.Morgan‚ Investigating Biology p.677). There are three types of behaviors: agonistic‚ orientation‚ and reproductive. Orientation is when the organism is placed in their beneficial environment consisting of two behaviors‚ taxis (movement directly towards or away something) and kinesis (random movement). Reproductive is detected using drosophila in this lab‚ it consists of finding courting and mating with another of the species Agnostic
