mutations (changes) in a gene on chromosome 7‚ one of the 23 pairs of chromosomes that children inherit from their parents. Cystic fibrosis occurs because of mutations in the gene that makes a protein called CFTR (cystic fibrosis transmembrane regulator) (Warrell‚2003). A person with CF produces abnormal CFTR protein — or no CFTR protein at all‚ which causes the body to make thick‚ sticky mucus instead of the thin‚ watery kind. People who are born with CF have two copies of the CF gene. In almost all people

Yersinia Pestis November 21‚ 2013 Introduction Yersinia pestis is a gram negative‚ rod-shaped‚ facultative anaerobic bacterium‚ known for causing the plague. The reason why Y. pestis is so successful is because of their elusiveness to the host’s immune system and their ability to suppress it. Traces of the plague go as far back as to ancient times and specifically 5th century BC Athens and Sparta. Pathophysiology “Y. pestis produces two anti-phagocytic

1. Describe and discuss the connection between parenting styles and attachment. Sigelman and Rider (2006) state that “Many noted theorists have argued that no social relationship is more important than the first: the bond between parent and infant”. Both Freud and Erikson placed great emphasis on the parent-child relationship and its importance to “normal” development. Freud believed that the human child is born with natural instincts and drives. The relationship that the caregivers had with

adaptation and this is a very valid point in evolutionary psychology. There are a variety of arguments relating to evolutionary psychology such a nature versus nurture debate which is in the process of deciding whether human behaviour is determined by genes or is it more decided by the environment humans are in. Charles Darwin attempted to explain the vast diversity of living organisms‚ so put forth the idea that we evolved from the very basic of human beings and since then we have had to adapt

Science of Controlled Breathing. Breathing is so natural that one hardly thinks about breathing unless he has trouble in breathing due to ill health. It is capable of keeping the organism live i.e.‚ the Self prolongs the established connection with the body. If one begins getting will to know about breathing‚ I am sure he has the prospective chance of knowing his Self which is also natural. Breathing is a process by which the Self keeps its assumed body live with all its instruments that helps to

INTRODUCTION In today’s world of corporate Leadership‚ many seem to share the belief that it is possible to send employees to a series of classes and make them leaders. Well‚ we are here today to alert everyone that ’Leaders are born‚ they are not made’! How often have you seen people promoted into a position of leadership‚ but they lack any of the qualities of a true leader? I am sure that this happens in our homes‚ churches and other areas of life‚ but today. WHO ARE LEADERS? Who is a leader

Understand the role of condensation reactions in joining the components of nucleotides and in the formation of di- and polynucleotides (nucleic acids). 5. Outline the structure of nucleosomes‚ including reference to the role of histone proteins in packaging of the DNA in the nucleus. 6. Understand that DNA contains repetitive sequences and that only a small proportion constitutes genes. Appreciate the role of repetitive sequences in DNA technologies such as DNA profiling. 7. Describe the Watson-Crick

‘restrict’ foreign DNA that enters a cell. Restriction enzymes are used today in biotechnology to cut DNA into smaller strands to study fragment length differences. This is known as restriction fragment length differences (RFLD)‚ or also known as gene cloning. There are three types of restriction enzymes: Type one cut the DNA at random regions as far as one thousand or more base-pairs from the recognition site. Type two enzymes are often used in biotechnology; they cut DNA within a recognised
