Solution: Teen Away uses your computer as a way of generating unpleasant high frequency sounds that only children / teenagers can hear. Adults (anyone over approx >25 years of age) will generally be unaware of the sound. You run the software and generate a sound that they will want to get away from.
The four types of chromosomal mutation are deletion, duplication, inversion and trasnlocation. Deletion is the loss of all or part of a chromosome. Duplication is where a segm â¦ ent of a chromosome is copied. Inversion is where a section of a chromosome is reversed.nsertion, Deletion and Frameshift mutation. These are the 3 basic types of mutation, however, there are other types of mutations: substitution, translocation, duplication, in â¦ version, transversion and transition.
Arg677stop and 2280del5 are the much studied RP1 mutations. 1  Autosomal Recessive retinitis pigmentosa â these are rarer genetic mutations. RPE65 (expressed in the RPE), and PDE6A and PDE6B cause 2-5% of cases and mutations in USH2A may account for up to 5% of autosomal recessive cases. X-Linked retinitis pigmentosa â in this type common mutations are seen in RPGR (also called RP3) and RP2 genes. They account for 70-90% and 10-20%, respectively of all X linked cases. Mitochondrial Genes Causing Nonsyndromic retinitis pigmentosa include mutations in the MT-TS2. Digenic retinitis pigmentosa â this is caused by combined presence of a mutation in the RDS gene and a mutation in the ROM1 gene.
