She has fifteen years of experience teaching the Sciences at KS3 to KS5, and Psychology at A-Level. * The role of channel and carrier proteins in membrane transport * Patterns of inheritance, in the context of monohybrid inheritance 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. This website and its content is subject to our Terms and In conclusion cystic fibrosis is genetic and if you have this disease you dont have long to live with an average life expectancy of 32. * The nature of the genetic code Miller, C.; Miller, M.; McMullin, B.; Regev, G.; Serghides, L.; Kain, K.; Road, J.; Av-Gay, Y. ; Rogasi, P.G.

This lesson describes how the expression of a gene mutation impairs the functioning of the gaseous and digestive systems in people with cystic fibrosis. ; and funding acquisition, M.R.P. 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. Currently, there have been few reported cases of phage therapy in humans, e.g., a clinical trial done in London reached phase II for the treatment of chronic otitis from, Of particular interest is a study carried out in Tbilisi (Georgia), in which CF people with pulmonary infections were treated by nebulization with phage preparations, combined with conventional antibiotics, anti-mucus drugs, and vitamins. This lesson bundle contains 16 lessons which have been designed to cover the Pearson Edexcel A-level Biology A (Salters Nuffield) specification points which focus on the structure of DNA and RNA, their roles in replication and protein synthesis, and genetics and inheritance. most exciting work published in the various research areas of the journal.

Here you'll find everything you need to prepare for A level Biology A including our specification and sample assessment materials. 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.

Interestingly, the latter was able to eradicate four cases of paediatric dysentery in 1919 in Paris using the administration of a phage preparation [, Therapeutic bacteriophages are pathogen-specific and safe for human tissues [. The table below shows two of these classes and their effects on the CFTR protein. Phage therapy of. Another strength of AVT is that this approach should keep the host microbiota healthy, lacking the undesirable side effects typical of antibiotic therapy [, Some limitations in the use of AVT are, however, to be expected. ; Daley, C.L.

We are very short of teaching time so I will abbreviate it but still keep the logical steps which are very well put. 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 - needle into the amniotic fluid via the abdomen to collect fetal cells that fell off the placenta or foetus, Chorionic villus sampling The mucus becomes thick, sticky, and hard to move. * Understand how the structure of the mammalian lung is adapted for rapid gas exchange 2.14 (ii): Know that some mutations will give rise to cancer or genetic disorders, but that many mutations will have no observable effect In addition, the timing of treatment administration must coincide with the regulation and the subsequent production of the target factor during the infection process. ; Sangen, J.; Wuest, A.W.

Again, the students are guided through the events that lead to the depletion of the apical surface liquid and the cilia being unable to move the viscous mucus. Simoes, D.; Miguel, S.P. The topic also allows for discussion of the social and ethical issues surrounding the genetic screening for genetic conditions. [, Therefore, being as this preliminary evidence very promising, it is advisable to continue to study the use of NO as an alternative strategy to treat, Phage therapy (PT) represents an old idea which has acquired renewed importance thanks to the successful recent case reports, where antibiotic-resistant lung infections in CF people were treated [, PT refers to the use of phages to fight bacterial infections.
