High-quality assessments: Unbeatable support, First teaching: 2015 Cystic fibrosis also affects the digestive system. Cystic fibrosis is a genetic disorder of cell membranes It results in the body producing large amounts of thick, sticky mucus in the air passages Over time, this may damage the lungs and stop them from working properly Cystic fibrosis is caused by a recessive allele ( f) This means: It affects organs in the body, particularly the lungs and digestive system, which become clogged with sticky mucus, making it difficult to breathe and digest food. * The structure of DNA and RNA 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. It affects about 1 person in 2000. ; Gaillard, J.L.

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. First assessment: 2017.

What happens if there is excess water in an unaffected person's airways? When the CFTR protein is defective, epithelial cells can't regulate the way chloride passes across cell membranes. The mucus becomes thick, sticky, and hard to move. Intracellular pathogens evolved to infect, colonise, and duplicate within host cells, managing to hide from the host immune system [, This lack of appropriate classical therapies has different causes, including antimicrobial resistance (AMR) which could have several mechanisms, such as the misuse of antimicrobials in both the healthcare and veterinary sectors.

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. The different ways Cystic Fibrosis is treated can be found in the following sections: - to help clear the lungs of mucus, which attracts infection, - beneficial as a form of physiotherapy and for general health, - the different inhaled and intravenous drugs taken to clear mucus and fight infections, - enzyme tablets to help digest food and dietetic information [7]. Boeck, L.; Burbaud, S.; Skwark, M.; Pearson, W.H. As well as explaining that this channel allows chloride ions to flow across the apical membrane of the epithelial cells, time is taken to emphasise the importance of its inhibition on the ENaC, which prevents the flow of sodium ions back into the cells.
