First assessment: 2017. Cystic fibrosis is a genetic disorder of cell membranes caused by a recessive allele of the CFTR ( C ystic F ibrosis T ransmembrane Conductance R egulator) gene located on chromosome 7 This gene codes for the production of chloride ion channels required for secretion of sweat, mucus and digestive juices CFTR transports chloride ions (Cl-) ions across the membranes of cells in the lungs, liver, pancreas, digestive tract, reproductive tract, and skin. 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. Recently, Dedrick et al. There are different ways that a mutation in the DNA base sequence can occur: Remember that every group of three bases in a DNA sequence codes for an amino acid, This means that insertion mutations cause what is known as a, Like an insertion mutation, a deletion mutation, Substitution mutations can take three forms, Note that a stop codon provides a signal for the cell to stop translation of the mRNA molecule into an amino acid sequence, Duplication is a type of mutation that involves the, A whole gene or section of a gene is duplicated so that, Overtime, the second copy can undergo mutations which enable it to develop new functions, Gene and chromosome duplications occur in all organisms, though they are, Inversion mutations usually occur during crossing-over in meiosis, The result is a large section of the gene that is 'backwards' and therefore multiple amino acids are affected, Inversion mutations frequently result in a non-functional protein, In some cases an entirely different protein is produced, The mutation is often harmful because the original gene can no longer be expressed from that chromosome, If the other chromosome in the pair carries a working gene the effect of the mutation may be lessened, The polypeptide can affect the phenotype, e.g. ; Rogasi, P.G. Cystic fibrosis (CF) is a genetic condition that affects a protein in the body. * Structure and properties of cell membranes One possible drawback is the extreme specificity of phages in targeting bacteria; thus, bacterial susceptibility is needed prior to choosing the suitable phage(s) [, Furthermore, a variation in MABSC phage susceptibilities was found [, The most important issue to solve is the possible resistance to phages induced by the treatment. CFTR transports chloride ions (Cl. ) A step by step guide is then used to describe the sequence of events that result in mucus which is motile and can be moved by the wafting action of the cilia in healthy individuals. 1.1.2 The Importance of Water in Transport, 1.1.3 Mammalian Heart: Structure & Function, 1.1.4 Blood Vessels: Structure & Function, 2.1 Gas Exchange, Cell Membranes & Transport, 2.1.1 Properties of Gas Exchange Surfaces, 2.1.5 Practical: Investigating Membrane Structure & Permeability, 2.3.6 Globular Proteins: Structure & Function, 2.3.7 Fibrous Proteins: Structure & Function, 2.3.10 Practical: Investigating the Effect Enzyme and Substrate Concentrations, 3.2.3 Practical: Identifying Mitosis in Plant Cells, 3.3.4 Meiosis: Source of Genetic Variation, 4.1.2 Measuring Biodiversity Within a Habitat, 4.1.3 Comparing Biodiversity Between Habitats, 4.2.3 Importance of Water & Inorganic Ions to Plants, 4.2.4 Starch & Cellulose: Structure & Function, 4.2.6 Practical: Identifying Tissue Types Within Stems, 4.2.7 Practical: Determining the Tensile Strength of Plant Fibres, 5.1.4 Practical: Determining Distribution & Abundance, 5.1.7 Calculating the Efficiency of Biomass & Energy Transfers, 5.3.2 Evidence for the Causes of Climate Change, 5.3.7 Practical: Temperature & Development of Organisms, 5.3.8 Climate Change & the Scientific Community, 5.3.9 Carbon Cycle & Reduction of Atmospheric Carbon Dioxide, 5.4.3 Evidence of Evolution & the Scientific Community, 6.1.2 Micro-organisms: Decomposition & Nutrient Recycling, 6.2.9 Evolutionary Race Between Pathogens & Host, 7.2.6 Practical: Investigating the Rate of Respiration, 7.4.1 Variations in Breathing Rate & Heart Rate, 7.4.2 Practical: Investigating the Effects of Exercise, 7.4.4 Modern Medicine & Participation in Sports, 8.1.3 Nervous System: Response to a Stimulus, 8.2.4 The Role of Animal Models in Research, 8.2.6 Imbalances in Brain Chemicals Leading to Diseases, 8.2.10 Nature vs Nurture in Brain Development. 1) Thick mucus blocks the pancreatic duct.

This leads into the section of the lesson which considers the inheritance of cystic fibrosis in an autosomal recessive manner and then focuses on the change in the primary structure of the channel which results from one of over 1500 different gene mutations. Formerly called mucoviscidosis, CF is an autosomal recessive genetic disease caused by mutations in the CFTR (Cystic Fibrosis Transmembrane Regulator) gene. 2. 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. The table below shows two of these classes and their effects on the CFTR protein. 2.7: Understand the nature of the genetic code Collect photographs of garments from fashion magazines and sales catalogs. - can lead to designer babies Cystic Fibrosis Mutation Database. - Cheek swab screened against common mutations before having children IBO was not involved in the production of, and does not endorse, the resources created by Save My Exams.
