Drosophila Melanogaster Research Paper

Introduction
When analyzing biological processes and development, Drosophila melanogaster is an ideal organism to utilize. Compared to other organisms, the functions of D. melanogaster are easier to manipulate due to its quick sedation time from carbon dioxide. These flies can be sedated in less than ten seconds with a carbon dioxide flow rate of 5L/min. D. melanogaster also produces offspring in a short amount of time (roughly 10 days at 25 degrees Celsius), which makes it a desirable species to use when results are needed in a short amount of time (Jennings 2011). These two characteristics allow a variety of experiments to be conducted on D. melanogaster. For example, different strains of DNA were injected into the embryos of D. melanogaster

CPD has three different CP-like domains. The first and second domains are active, while the third is inactive. In D. melangaster, CPD undergoes splicing, produces six forms of mRNA, and then produces proteins (Holger et al. 2011). It seems that the timing for expression of CPD is different compared to wild-type flies because Gal4 is expressed and encourages the transgene expression for the upstream activating sequence (UAS) promotor. Because of this timing difference, certain CPD substrates may not be processed in the time it would take a wild-type fly to process them, which could explain the different characteristics between the flies (Sidyelyeva et al. …show more content…
This incorrect fold is what may give rise to the "sv" "r" ^"1" pointed wing mutation. The "sv" "r" ^"poi" variant has a nonsense mutation, which means that the protein does not form to its normal length. Because of this, the protein is not completely functional, which alters the function of the normally produced protein. Some of these proteins act as growth factors in D. melanogaster (Sidyelyeva et al. 2006). The alteration of growth-factor proteins in "sv" "r" ^"1" and "sv" "r" ^"poi" mutants could explain the changes in wing phenotype (Sidyelyeva et al.

    ii. Concerns of difference in splicing between reproductive tissue and embryonic tissues. The mutation of the gene trap does not become effective until the inserted vector is spliced together with the exon next to where the vector is inserted. Genes also have testis and ovary specific splicing sites; therefore it can also disrupt the testis and ovary isoforms. iii.…

    In the nucleus, Smads are also able to participate in histone modifications and chromatin remodeling (Ross et al., 2006 [53]). Anyway, some transcription factors like Runx1, Runx2, and Runx3 in concert with R-Smads and/or Smad complex plays critical roles in mediating specific signals to regulate the transcription of ultimate target genes. Essentially, Runx2 regulate osteoblasts formation and activate the expression of other osteogenesis specific target genes. The β subunit of PEBP2 stabilizes Runx2 by preventing ubiquitin-dependent degradation (James, 2013 [54]). Upon activation of BMP…

    Translation may occur in either the cytoplasm or the rough endoplasmic reticulum. Two molecular factors that play a key role in translation are transfer RNAs (tRNAs) and ribosomes. tRNA is a RNA molecule that carries amino acids to the ribosomes where they will be added to a growing polypeptide chain. They contain a base pair of 3 amino acids that can bind to the complementary mRNA codons. The relationship between codons and amino acids is known as the genetic code where it defines how sequences of codons specify which amino acid will be added next.…

    One way to prove their functions is to use conditional KO strategies as conventional KO of some of enzymes, leading to embryonic lethality. A shift of transcriptome (from maternal transcripts to zygotic transcripts: known as maternal-to-zygotic transition (MZT)) is known to occur during mammalian preimplantation development. A recent study showed that Xenopus oocyte mRNA methylation can regulate translation and cell division during meiosis and early embryo development. Therefore, m6A may possibly play a role in the process of MZT. Finally, the involvement of m6A in onset or progress of human diseases is still elusive.…

    To examine whether these candidates are also altered in pancreatic ASC, I will analyze the RNA levels of top targets in pancreatic ASC samples that contain UPF1 mutations. To determine the function of the identified candidates from high-throughput sequencing, I will perform overexpression and knockdown experiments in primary pancreatic cell lines to examine for corresponding gain or loss in proliferation. In addition, I will determine whether overexpression of the candidates transforms primary pancreatic cells. In summary, results from this aim will elucidate the mechanism by which UPF1 mutations promote pancreatic…

    Polyploidy Essay

    The presence of gene redundancy in organisms is because of genome duplication and polyploidy. Polyploidization process is believed to be followed by genomic rearrangement or gene slicing which facilitates diploidization. Polyploidy results to neofuncitonalization and subfunctionalization of genes. Neofunctionalization refers to the acquiring of new functions for the existing genes while sunfunctionalization refers to the process of limiting the functions of the gene. DNA methylation pattern changes and Chromosomal rearrangements are occur greatly in plolyploids and this resulted to variations in the process of gene expression and gene regulation.…

    Result and Discussions 3.1. Changes in catalytic pocket Instead of having the conventional catalytic triad residues (His665, His667 and Asp767) in it’s protease domain, Lon protease employs the Ser679 – Lys722 catalytic dyad to form a catalytic pocket for promoting proteolysis. But the mutations in catalytic dyad residues make some changes in the catalytic pocket of these three mutant types. A comparison of SASA values and RSA values [Supplementary file 1] were done among the catalytic pockets of wild type Lon protease and the three different mutant types of Lon protease. The catalytic pocket of wild type Lon protease shows a SASA value of 5840.7Å.…

    Therefore, the plants could die out if the insects that pollinate them were killed. Also, GMO’s are more widely used which means that the original version of the genetically modified crops are diminishing. These original plants contain natural genes that are beneficial to health in certain ways such as vitamins. Through genetic modification the natural genes could be lost. Also, though it is not yet proven, genetically modified organisms could potentially form more toxic allergens that could potentially be worse than allergens already found in the organism.…
