CHAPTER 2: CELLS Learning about disease is often simplified by growing it in a dish – some cells like heart and nerve cells however do not grow easily outside the body. Cellular reprogramming takes cell back to a state similar to stem cells and then coaxes them to specialize in a different way. Example – LEOPARD syndrome MIM 151100. Acronym for symptoms: enlarged heart w/blocked valves to the lungs‚ freckles‚ abnormal genitals‚ deafness. Skin cells taken from patients were reprogrammed to give

Recessive and dominant genes Genes are genetic instructions that define what we look like‚ a phenotype‚ and how our cells are made up‚ a genotype. “Genes are made up of DNA and are organized into larger structures called chromosomes‚ which are

schizophrenia. Many genes have been linked to the development of schizophrenia but not one gene can cause the disorder without influence from other genes present in the genotype. As stated by Pinel‚ concordance rates for schizophrenia are higher in identical twins (45%) than in fraternal twins (10%) as identical twins share the same genotype from their biological parents (449). This demonstrates the correlation between the effects of gene inheritance and the development of schizophrenia. Additionally‚

GENETICS JARGON Alleles (allelomorphs) Alternative forms of a particular gene. There can be several alleles of a particular gene in the population‚ but only 2 alleles can be inherited by a single individual. For simplicity much literature aimed at the general reader uses "gene" where it means "allele". Allelic Series A series of alleles that are all mutant forms of the same gene and are at the same locus (same position on the chromsome). Alternate Heredity Mendelian inheritance involving

Introduction: * Genetics are composed of five main areas: DNA replication‚ meiosis‚ reproduction‚ adaptation and evolution. The body is composed of 46 chromosomes (23 from your mother and 23 of your father). The genes are in your cells in the nucleus and some in the mitochondria. The genes are a small part of a long molecule called DNA. DNA is a double stranded molecule (sugar‚ phosphate and four different bases: Adenine‚ Thymine‚ Cytosine and Guanine). The bases in the DNA are

Neurofibromatosis My disorder research paper is about neurofibromatosis‚ which is a genetically-inherited disorder in which the nerve tissue grows tumors that may cause serious damage by compressing nerves and other tissues. The disorder affects all neural cells such as the Schwann cells and melanocytes. The melanocytes function abnormally in this disease‚ resulting to disordered skin pigmentation. The tumors would be able to cause bumps under the skin‚ colored spots‚ skeletal problems‚ and other

After much thought and consideration‚ I have come to the difficult conclusion that having an abortion would be the most humane decision‚ not only for the baby‚ but for myself (the mother) and for my theoretical spouse‚ children‚ and other family members. Trisomy 13 is an awful chromosomal abnormality that has no cure. This is not a disease such as down syndrome that a child could live with. Research has shown that most babies with Trisomy 13 do not even live to be a year old. The rare percentage
