A-level Biology) This lesson bundle contains 16 lessons which have been designed to cover the Edexcel International A-level Biology specification points which focus on the structure of DNA and RNA, their roles in replication and protein synthesis, and genetics and inheritance. People with cystic fibrosis have a shorter life expectancy, with the average being around 31 years [3]. ; Essi, L.; de Campos, M.M.A. Genetic screening can be used to test for the Heifets, L. Mycobacterial infections caused by nontuberculous mycobacteria. * The nature of the genetic code Cystic Fibrosis is UKs most common life threatening inherited disease [1]. Due to the detail included in each of these lessons, it is estimated that it will take in excess of 2 months of allocated teaching time to cover the content. The Burkholderia cepacia complex (Bcc) is a group of bacteria including opportunistic human pathogens. * The formation of polypeptides and proteins Combined Science Biology Chemistry Physics AQA. * Understand how the structure of the mammalian lung is adapted for rapid gas exchange The Cystic Fibrosis Foundation is a . 2.16: Understand how the expression of a gene mutation in people with cystic fibrosis impairs the functioning of the gaseous exchange, digestive and reproductive systems Signup as a free member below and you'll be brought back to this page to try the sample materials before you buy. ; Waldbrook, M.; Mullaly, S.C.; Volkmer, R.; Hancock, R.E. Background information I would give to the student: This question is a perfect example which shows that if you really understand the topic, it becomes easier to remember the facts for the questions relating to it. The main focus of the lesson is the CFTR gene and the functions of the ion channel that is synthesised when this gene is expressed. Cystic fibrosis makes peoples lifes harder because it not curable at the moment, you can use medication to stop the pain of Cystic Fibrosis. Then determine whether each is a need or a want. 1) Chloride ions are pumped into the epithelial cell causing a concentration gradient and the CFTR channel protein opens 2) Chloride ions diffuse into the mucus through the CFTR protein 3) This closes the ENaC 4) The build up of chloride ions creates an electrical gradient so sodium ions diffuse into the mucus between the gaps in epithelial cells Cystic fibrosis is a rare, life-restricting, genetic disorder, with multi-organ involvement [].Due to a defect in the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene, approximately 70,000-100,000 patients worldwide currently suffer a wide range of symptoms [1,2].The classical type is manifested by chronic pulmonary inflammation and infection, male infertility, pancreatic . Opportunities for developing mathematical skills within this topic include calculating areas of circumferences and areas of circles, surface areas and volumes of rectangular blocks and spheres, using ratios, fractions and percentages, plotting two variables from experimental or other data, determining the slope and intercepts of a linear graph, understand that y=mx+c represents a linear relationship, drawing and using the slope of a tangent to a curve as a measurement of rate of change, understanding simple probability and completing a statistical test. Cystic fibrosis (CF) is a genetic condition that affects a protein in the body. Nanoniosomes were not effective in vitro against, In conclusion, even if nanomedicine is a powerful tool used to successfully treat many diseases, only a few studies have been established to treat. 3.8 (i): The loci is a location of genes on a chromosome What happens if there is too little water in an unaffected person's airways? This deletion causes loss of the amino acid phenylalanine located at position 508 in the protein; therefore, this mutation is referred to as delta F508. All of the questions included in the lesson have mark schemes which are embedded into the PowerPoint and this allows the students to assess their progress.

Membranes, proteins, DNA and gene expression represent some of the most important structures, molecules and processes involved in this subject and a deep understanding of their role in living organisms is important for a student's success. They have been successfully used to treat a plethora of diseases, from cancer to infections and as putative wound dressing [, Recently, those tools have been also investigated as putative weapons against, One example is gallium-based nanoparticles, which showed significant results in blocking, The efficacy of liposome encapsulated rifampicin compared to free rifampicin, in an ex vivo, Nanoniosomes are vesicles with a composition similar to that of the cell membrane (named niosomes) that have been loaded with antibiotics or lignin-silver nanoparticles. ; Saiman, L.; Daley, C.L. * A gene is a sequence of bases on DNA that codes for the amino acid sequence of a polypeptide ; Gaillard, J.L.

Choi, S.R. ; Fensterseifer, I.C. -Stressful and expensive ; Huang, T.T. * Understanding the pattern of monohybrid inheritance However, strange as it may seem, my real love is designing resources that can be used by other teachers to maximise the experience of the students. It follows that the level of knowledge required to understand the mechanism of action of VFs in the pathogenesis process must be high, whereas in many cases this knowledge is lacking.

If you have cystic fibrosis, this mucus is excessively thick and sticky and cannot perform this role properly. When a CFTR protein with the delta F508 mutation reaches the ER, the quality-control mechanism of this cellular component recognises that the protein is folded incorrectly and marks the defective protein for degradation. ; Ribeiro, M.P. ), are all examples of nanomedicine tools, powerful drug delivery systems with the advantages of high efficiency and specificity and a sustained drug release over time at the target site.
