Question for assignment: Using a transgenic technique, propose an experiment to determine whether Cdx2 is sufficient for trophoblast development in the mouse embryo. Describe two results that you would expect to observe at the blastocyst stage if Cdx2 is indeed sufficient for trophoblast development. Be as specific as possible regarding the transgene that you propose for this experiment (including what gene's enhancer you would use in the transgene). Note: you do not need to explain the details of how a transgenic mouse is made. Describe the experiment in steps (Step 1: ..., Step 2: ... etc) and please keep your answer to under 150 words.  TIPS FOR ANSWERING: DONT talk about stop cassetes/memory cassetes, focus on transgenes Paper (below) gave lots of results that you might see,, 6 diff ways that cdx2 is required for trophoblasts need specific gene enhancer (dont just say "expressed enhancer in genital ridge")

genetics question for Icke P. Jenny, like her mother, is heterozygous for both X-linked traits. Her father suffered from bothhypophosphatemia and muscular dystrophy. Jenny’s fiancé, Mark has a mother suffering from musculardystrophy despite having normal bone conditions. His father has been blessed with strong bones andmuscles but suffered from amelogenesis imperfecta. a. Give the complete genotypes of the following individuals:  Jenny, Jenny's mother, Jenny's father, Mark, Mark's mother, Mark's father. b. Should Jenny and Mark eventually marry, what is the probability that they will have: a child with muscular dystrophy, a child with amelogenesis imperfecta, a son with hypophosphatemia, a daughter with muscular dystrophy, a child with the same genotype as Jenny, a child with the same genotype as Mark

Please answer fast Please answer the questions   1.Transcription factors (TFs) bind to promoter sequences on DNA because the shape of DNA at that particular location matches the shape of the TF and intermolecular interactions (using hydrogen bonds) are NOT used stabilize the interaction.   Group of answer choices   True or False   2. In a pre-mRNA molecule, the _________ are regions that do NOT code for amino acids and are removed.   3. The fact that the main enzyme used in transcription is a DNA-dependent RNA polymerase means that is makes _________ using ____________ as the template.

how do i expand this into 1000 words for a result section of a report   The objective is to interpret the results of an RNA-Seq analysis to identify differentially expressed genes in breast cancer using figure 1. The data provided includes gene symbols, chromosome location, start and end points, strand, fold change, log2 fold change, p-value, and false discovery rate (FDR). The RNA-Seq analysis has identified several genes that are differentially expressed in breast cancer. These genes are located on various chromosomes and have varying levels of fold change, indicating the degree to which their expression levels differ between normal and cancerous cells. The gene with the highest fold change is EYA4, located on chromosome 6, with a fold change of 3604.4176. This indicates that the expression of this gene is over 3600 times higher in cancer cells compared to normal cells. The log2 fold change is 11.81555, which is a measure of the magnitude of the difference in gene expression. The…

(E) identify the source of DNA material Questions 21-23 A culture of white-eyed fruit flies (Drosophila melanogaster) was maintained for many generations. Females from the stock white-eyed culture were crossed with red-eyed (wild-type) males. The F1 females were crossed with the white-eyed males from the original culture. The resulting phenotypes of the progeny are summarized below. Parental Generation Cross F1 Generation (at least 500 flies) 100% of females are red-eyed 100% of males are white-eyed White-eyed females x red-eyed males F1 Generation Cross F2 Generation (at least 500 flies) Fl red-eyed females x white-eyed males 50% of females are red-eyed and 50% are white- eyed 50% of males are red-eyed and 50% are white-eyed 21. The best explanation for the red-eyed F1 females is (A) mutation (B) culture contamination (C) dominance (D) multiple loci (E) sex-influenced traits 22. There are white-eyed females in the F2 generation because (A) white is a dominant allele (B) the white…

Assignment SummaryIn this assignment, you will think of scientific questions that will help you better understand the role ofDNA and chromosomes in the expression of heritable traits in an organism. You will then conductresearch to answer these questions. Finally, you will compose a typewritten document that states yourquestions and provides your answers.Background InformationDNA in the nucleus of a cell contains the genetic code that dictates the structure and function oforganisms. DNA is compressed into structures called chromosomes. Chromosomes are made ofsegments of DNA called genes. Genes are the basic units of heredity in organisms and are transferredfrom parent to offspring.DNA contains the genetic code, or the set of instructions, in the form of triplet codons, for assemblingamino acids into proteins. All organisms share a similar genetic code based on the same DNA codons.The order of the codons differs, allowing for diversity among organisms.Not all DNA codes for proteins.…

how do i expand this into 1000 words The methodology employed to identify differentially expressed genes (DEGs) in breast cancer using RNA-Seq data involves several systematic steps integrating data retrieval, analysis, normalization, DEG identification, and functional annotation. Initially, raw RNA-Seq data is retrieved from the NCBI GEO database, specifically from dataset GSE216238 (Nakshatri, 2023), which encompasses samples from both breast cancer and normal tissue. Subsequently, the raw data was imported into Excel for initial analysis, leveraging its widespread availability and user-friendly interface. Gene expression data for breast cancer analysis was obtained from the Gene Expression Omnibus (GEO) database. The GEO homepage (https://www.ncbi.nlm.nih.gov/geo/) was accessed, and the "Query & Browse" tab was selected. Advanced Search: Under "Search GEO DataSets," an advanced search was conducted (https://www.ncbi.nlm.nih.gov/gds/advanced). Keywords "breast" and "cancer" were…
