Recklinghausen’s disease‚ also called Neurofibromatosis Type I (NF1) is one of the most common types of inherited single gene disorder which effects approximately 1 in a disorder caused by a mutation in the tumor suppressor neurofibromin (NF1) gene located on chromosome 17 q11.2 and is inherited in an autosomal dominant manner. The neurofibromin gene primarily affects the development and growth of neural cell tissues as well as the regulation of melanogenesis so the defect in this gene typically causes neural cell

SYMPTOMS OF TURNER SYNDROM Medically Reviewed Short stature; one of the missing genes in the “X” chromosome is the SHOX gene. This gene is responsible for the long bone growth development; “more than 95% of adult women with Turner syndrome exhibit short stature”. Without it‚ your bones don’t grow the way they should; average adult height with Turner syndrome is 4 feet 7 inches. “Scoliosis affects the spine and occurs in 10% of young girls with Turner syndrome

W4Q1 Meiosis is the process by which cells divide and create living creatures. Without meiosis we cannot have the process of mitosis‚ which is the process by which cells of tissue are created for living creatures. When meiosis occurs 4 daughter cells are created‚ while only 2 are created in mitosis. With the creation of 2 daughter cells the new cells will be similar to the parent cell‚ but will have differences‚ as there more parent cells involved. When mitosis occurs the daughter cells will be

humans. P53 is the most studied gene in the history of cancer biology and research. P53 was originally discovered by experiments and studies done on SV40- trans formed cells (Weinberg 2014). In humans‚ the p53 gene is located on the short arm of chromosome 17. Its coding sequence demonstrates high conservation in vertebrates specifically at exons 2‚

through a process called binary fission and eukaryotic cells reproduce through a process called mitosis. DNA structures of eukaryotic cells are far more structured than that of prokaryotic cells. The DNA of eukaryotic cells is organized into chromosomes and the DNA of prokaryotic cells is a single loop. Both prokaryotic and eukaryotic cells gain the energy it needs to develop and maintain functionality by a process of cellular respiration. Basically‚ cellular respiration is broken down in three

This tree shows the similarities found between all of the species that were listed on the ortholog search. This helps in narrowing down what the exact function of the gene is. It was determined that the species‚ Danio rerio‚ Xenopus tropicalis‚ Mus musculus‚ Rattus norvegicus‚ and Homo sapiens all shared similar functions for this gene. Thus the assumption was made that L. cuprina had to have a similar if not exactly the same as the closest species to it. Reading the tree‚ that species would have

Objectives of the Study This study evaluates the genotoxicity‚ and teratogenicity/antiteratogenicity of the methanol leaf extracts of Tamarindus indica (TE). In particular‚ the study aims to: determine the genotoxicity of TE in terms of: mitotic index chromosomal aberrations micronuclei formation assess the developmental toxicity and teratogenicity potential of TE to zebrafish embryos; and verify the potential of TE to rescue zebrafish embryos from ethanol-induced teratogenicity.
