When we experimentally hop a P-element out of a mutation caused by a P-element inserted in the coding region of a gene, we sometimes regain gene function, although, as I explained in class this is very unlikely. What is or are possible reasons gene function is regained?

Answer #1

When we remove the P element accidentally we might regain the gene function because the reading frame now reverts back to the original form and the genome once again functions as usual. So there is a possibility that with the removal of the P element the gene may revert back to its original composition. Also if the P element hops to a non coding region it would not affect the gene expression at all because of the splicing mechanism which the RNA undergoes before the translation of the protein in which all the non coding genes are removed therefore it is possible that the P element does not interfere the gene function.

    Change of Variables When working integrals, it is wise to choose a coordinate system that fits the problem; e.g. polar coordinates are a good choice for integrating over disks. Once we choose a coordinate system we must figure out the area form (dA) for that system. For example, when switching from rectangular to polar coordinates we must change the form of the area element from drdy to rdrd0. To determine that rdrde is the correct formula how the edges of...

    2. A dominant allele H reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the "hairy" phenotype. However, S also is lethal in the homozygous (S/S) condition. What ratio of hairy to hairless flies...

    Hagrid has purified a protein from unicom sweat and called UNI-1. He has then doned the Unit gone and inserted in rat zygotes (by microinjection) a recombinant construct containing the Uni-1 coding sequence its entire 5 UTR region, covering both the minimal promoter and a series of cutative regulatory als elements. The mutantrats develop glorious, luminous hair. Hagrid has also discovered that the UNI-1 protein binds very tightly to DNA and hypothesizes it is a transcription factor that regulates proliferation...

    Hello I need help with this program. Should programmed in C! Program 2: Sorting with Pointers Sometimes we're given an array of data that we need to be able to view in sorted order while leaving the original order unchanged. In such cases we could sort the data set, but then we would lose the information contained in the original order. We need a better solution. One solution might be to create a duplicate of the data set, perhaps make...

    Explain the following in terms a highschooler would understand (from article Expression of HoxD Genes in Developing and Regenerating Axolotl Limbs, 1998): DISCUSSION: Expression of HoxD genes in developing axolotl limb buds. We have examined the expression of Hoxd-8, Hoxd10, and Hoxd-11 genes in axolotl limb buds and find many similarities between the patterns of expression in axolotls and those described for other vertebrates. Similarities are most pronounced in phases I and II (Nelson et al., 1996; Shubin et al.,...
