Describing theories TASK 1(P1) Introduction The theory I have chosen to discuss is the theory of inheritance‚ which is attributed largely to Gregor Mendel who lived from 1822 to 1884 and was considered to be a mathematical scientist who introduced the science of genetics. Observation During the period of 1858 to 1866‚ Mendel observed the different characteristics that where inherited by living creatures. He done this by breading garden peas in his monastery garden and analyzing the offspring

Liquid or fluid appearance is visible. Bacteria and background don’t have a much of difference in color. Although‚ bacteria are defined and visible noted. Most of the time they are single round cells. In direct stain with crystal violet‚ again background is colorless and glossy. Bacteria is blue and some

BACTERIAL MENINGITIS BY JAY DOMANTAY JAY DOMANTAY ANATOMY 151 HERBERT MAY 11‚ 2009 BACTERIAL MENINGITIS A bacterial infection of blood poisoning in the meninges called bacterial meningitis affects toddlers‚ adolescents and young adults. The infection strikes nearly 3‚000 Americans each year‚ and 10 to 12% of those infected will die. Among those who survive‚ approximately 20 % live with permanent disabilities‚ such as brain damage‚ kidney disease‚ hearing loss or loss of limbs.(“Prevention

Hox Genes | November 15 2010 | | Comparative Vertebrate Anatomy | Homeotic complex (Hox) genes are defined as a group of related genes that specify the anterior-posterior axis and segment identity of metazoan organisms during early embryonic development. These are situated very close to one another on the chromosome in groups of clusters. The orders of these genes located on the chromosomes are the same as the expression of the genes in the development of an embryo‚ whereas the first

Gene Therapy What is it? If genes don’t produce the right protein or don’t produce it correctly a person can have a genetic disorder. Gene therapy is an experimental technique that involves the transfer of a working copy of a gene into a cell to repair or replace a faulty gene so it is able to produce functioning proteins again. There are several approaches. The most common one is to insert a normal gene to replace the non-functional gene. Another approach is to swap a non-functional

When the Antibiotics Quit Working It seems as though antibiotics are slowly losing the battle against infectious disease thus causing a greater demand for researchers to invent new antibiotics that have new mechanisms for killing microbes as well as new vaccines. The problem is that bacteria are becoming resistant to antibiotics. When bacteria are exposed to antibiotics they are under “selective pressure” that allows

GENE MUTATION‚TYPES OF MUTATIONS 1. Gene Mutation A Gene Mutation is defined as an alternation in the sequence of nucleotides in DNA. It can affect a single nucleotide pair or larger gene segments of a chromosome. Mutations cause changes in the genetic code which lead to genetic variation and the potential to develop disease. What causes Gene Mutation? → Gene mutations are most commonly caused as a result of two types of occurrences. 1. Environmental factors Ex) chemicals‚ radiation

Tylenol Product Contamination case study “The risks and rewards to organizations of openness are illustrated by recent cases of crisis management run amuck and done well by highly visible corporations. In the 1980’s‚ Johnson and Johnson created the case study benchmark for crisis management with its handling of the Tylenol product contamination issue. Highly visible leadership and wide-open communication allowed the company to quickly rebuild customer trust in the Tylenol brand” (Patrick F. Bassett)

A gene is a long sequence of nucleotides on a DNA molecule. A mutation is a change in the amount of an organism’s genetic material and when a change in genotype produces a change in phenotype‚ the individual affected is said to be a mutant. A gene mutation involves a change in one or more of the nucleotides in a strand of DNA. The sequence of nucleotides in a gene controls the order in which amino acids are made into a protein‚ therefore if the sequence of nucleotides in a gene is altered by a mutation

(don’t wear gloves with messing with Bunsen burner only goggles‚ but use gloves when messing with chemicals ensuring goggles on all the time) 3. Clean your surface with disinfectant to sterilise your lab work surface‚ this will prevent contamination but leave the disinfectant to stand up to 4 minutes so it can penetrate the harder capsules of some bacteria. 4.
