 UCSC Genome Browser Part 3

6. a) The Repeat Masker screens DNA sequences for repeats and low complexity DNA sequences.

b) SINE, LINE, LTR, DNA, Simple, Low Complexity, Satellite, RNA, Other, Unknown

c) A densely shaded line represents a low number of combined base mismatch, base deletion, and base insertion associations.


10. a) LINE has the highest amount of associated repeats because it has the most amount of lighter shaded lines.

b) LINE and SINE have the largest present because they have the most dense lines.

c) It might be useful to see the frequency of SINES within a gene to see how well a gene might be able to be mutated or alter the expression.

d) Knowing the location of microsatellites can be useful because they can be used in tracking point mutations, DNA repair, and replication errors in the gene. 

e) Some assays that'll help a scientist with expression/gene regulation analysis would be PCR, CRISPR, RNA sequencing, and microarrays.

 Project Proposal      Hypothesis: By regulating the gene SLC5A1, we can also regulate the expression of the sodium-glucose cotransport 1 and the genetic disorder GGM. From this, we are able to induce GGM into a mouse through editing the gene. To test the expression of the mutation, we will feed the mouse food that contains glucose/galactose. If the mouse experiences diarrhea and excessive dehydration, we can conclude the gene editing as successful.       Introduction: For this semester, the digestive protein I chose all the way back in the beginning of February was sodium-glucose cotransport 1. Over the course of the semester, I learned a lot about this protein and the gene that is associated with it by traveling and mining information through different databases. Sodium-glucose cotransport 1 (SGLT1) is mainly found in kidney proximal tubes because it regulates sodium/sugar uptake levels in intestinal cells. The mutation in the gene that encodes ...

 UCSC Genome Browser Part 2 6. I. Description of the data: The NIH Genotype-Tissue Expression project is used to study genetic  variation and gene expression in human tissues. The track shows median gene expression in 52 tissues and 2 cell lines based on data from 17,382 tissues obtained from 948 post-mortem adults. II. Tissue samples were obtained using the GTEx operating procedures of tissue collection and specimens were reviewd by pathologists to verify the organ source. The Qiagen PAXgene non-formalin tissue preservation product was used to stabilize the specimens. The RNA-seq was performed by GTEx and were aligned to the human genome using STAR v2.5.3a assisted by the GENCODE 26 transcriptome defintion. Gene annotations were produced using a custome isoform collapsing procedure that excluded and then included extrons/introns. Gene expression levels were called via the RNA-SeQC tool after filtering it by unique mapping, proper pairing, and exon overlap.  III. The goal...
