Meiosis

been increased substantially. We are also now better equipped to develop drugs that can specifically treat those diseases and pathogens. An individual’s susceptibility to diseases can also be identified. Through the study of DNA, replication and meiosis, it is now easier for us to trace paternal lines using genetic coding. DNA has aided in forensics to a large extent, enabling us to identify victims as well as suspects in crimes by use of evidence such as saliva, hair strands and blood which…

mutation. Stop 10: Variation, selection, evolution into the human body 26. Variation is caused by recombination and mutation. Mutation is the random change is the genetic sequence, while recombination is the rearrangement of genetic material during meiosis. 27. The size and position of the spots were controlled by a single gene. In green leaves, the butterfly with wing spots has greater advantage over butterfly without wing spots. However, in brown leaves, butterfly without spots have a…

EDCI 509 Assignment #2 Development of Data Collection Instruments Introduction Data driven instruction is now getting more attention due to accountability issues that schools are facing. For my action research project, I will investigate the effects of using data to guide instructions and improve student learning. My primary action research questions are as follows: • What are the effects of using data driven instruction and goal setting to improve student learning and test scores in science?…

Gene Mutations Gene mutation is a permanent change in the DNA sequence that makes up a gene. Mutations are affected by the change in the DNA sequence. There can be many different types of mutations. (Department of Genetics, Stanford School of Medicine, Para I) Some examples are point mutations, missense mutation, nonsense mutation, frame shift mutation, silent mutation, deletion, insertion, and duplication. (US National Library of Medicine) These mutations can either occur naturally or actually…

Introduction Hutchinson Gilford Progeria Syndrome (HGPS) is a fatal disease that is characterized by the appearance of rapid aging in children. HGPS is rare, affecting roughly 1 in 8 million live births. HGPS can be identified by early symptoms that include slow development, limited growth, alopecia, localized scleroderma, and a distinct facial structure which includes a small face, shallow jaw, and pinched nose. As the disease progresses, new symptoms arise, such as hearing and vision loss…

According to the cell theory, the cell is the smallest form of life but there are many parts of a cell which allow the cell to do the job it is assigned correctly. An example of a cell would be the animal cell, which is a eukaryotic cell or a cell that contains a plasma membrane. Inside the membrane there are parts of the cell called the organelles. (Animal Cell Structure, 2005) Organelles inside the cell have specific jobs to perform for the cell, organelles include the ribosomes, vacuoles,…

The smallest unit within a living thing is known as a cell. Organisms are also a living thing and cell is considered to be the basic block of organisms that builds them. There are many different types of cells in a living thing and are divided into two main categories (i) prokaryotic and eukaryotic. (Karp, 2010). Characteristics of living cell Cells are considered as the most fundamental unit that has the responsibility to carry functions within a living organism (De Robertis & De Robertis,…

Abstract DNA recombination is basically generation of the new DNA sequence in genome by exchange of DNA strands. Recombination generally but not necessarily occurs between similar DNA sequences and provides genetic variation, genome integrity [1]. There are four main ways being identified to produce recombinant DNA; homologous recombination in which physical exchange of DNA sequences occur between the homologous chromosomes, illegitimate recombination occurs between DNA sequences sharing low…

Drosophila melanogaster: Inheritance Pattern Experiment Kaitlyn Grifka Saginaw Valley State University Abstract The purpose of this experiment was to study a population of Drosophila melanogaster, or more commonly known as the fruit fly. Our main goal was to determine if our flies displayed an autosomal recessive inheritance pattern or an X-linked recessive pattern based on the two different mutations that were existing in the population. Those mutations include having vestigial wings, sepia…
