What is TB? is one of the most common infections in the world. About 2 billion people are infected with TB and nearly 3 million people are killed by it each year. In Canada‚ there are about 1‚600 new cases of TB every year. The bacterium that causes TB is called Mycobacterium tuberculosis. Someone can become infected and yet not have any symptoms of the active disease - this is called inactive TB. Because the bacteria that cause tuberculosis are transmitted through the air‚ the disease can be contagious

RANELLE JANINE L. ASI BIO 120 S-5L EXERCISE 9. Genomic DNA Isolation & Exercise 10. Polymerase Chain Reaction (PCR) Cell and molecular biology is a science based on the various systems of a cell resulting to its regulation‚ maintenance and function. Many of these systems involve genetic information hence the study of the DNA is an essential part of this field. To able to analyze DNA‚ it must first be isolated and purified from its natural environment filled with biological molecules and compounds

This type of treatment can cause dislocated jaws and shoulders and even broken bones. It can also cause short-term and even long-term memory loss. Another biological treatment for unipolar depression is antidepressants. These include mono-amine oxidase (MAO) inhibitors‚ tricyclics‚ and selective serotonin reputake inhibitors (SSRIs). The different types of antidepressants have different ways of combating the symptoms of depression. Other ways that are used to treat depression are free association

this species of snails‚ samples were collected‚ DNA’s were extracted‚ undergone PCR and electrophoresis‚ and was sequenced and analyzed. The analysis was qualitative In the Philippines while quantitative in China. In the Philippines‚ the cytochrome oxidase subunit 1 (COI) genes was used and compared among the species collected and when it was sequenced‚ it showed differences due to localized gap‚ mismatch and non-correspondence of bases. And in China‚ the diversity was analyzed by means of Nei’s gene

Forks over Knives is a documentary detailing the global illnesses and obesity crises due to the “Western diet”. 40% of Americans are obese and over half are taking some form of prescription drug. Lipitor‚ a statin drug‚ is the most prescribed drug in the world‚ although there are genetic mutations many people have that are linked to statin sensitivity (1). More than 2.2 trillion dollars a year are spent on healthcare. More per person is paid on healthcare than any other industrialized country.

2.3.3 Effects of heavy metals on plants Plants are sensitive for both‚ deficient and excess availability of some of the heavy metal ions. In which some of them at low concentration are compulsory micronutrients‚ while the same at higher concentrations such as Cd‚ Hg‚ As are intensely toxic to the metabolic activities of the plants (Reeves and Baker‚ 2000; Fernandes and Henriques‚ 1991). Agricultural soil is contaminated by heavy metals‚ has become a critical environmental concern due to their potential
