When doing a lab that involves Extraction of Genomic DNA from adult Drosophila melanogaster. - What are the controls you should use and why use these? What is special about the genomic DNA? What do you expect to find (using these genomic DNA samples)? please help!
What are some of the technical challenges of cloning a mammoth? Check all that are true Ancient mammoth DNA has degraded so it is hard to know the complete genome sequence Mammoth gestation time is likely too short to allowing cloning A living surrogate mother would have to be used, which could pose problems since the closest relative to mammoths is endangered elephants A living oocyte would have to be obtained from an extant species, which could pose problems since the closest relative to mammoths is endangered elephants Mammoths lived so long ago that they used a different genetic code than modern animals There are no enzymes in existence that could ligate together mammoth DNA sequence with elephant sequence Mammoths probably had egg shells, which would be hard to penetrate with a needle
Follow these directions to access the entries for PTGS1 and PTGS2 in the “Gene” database at the NCBI Website:A. First, go to the NCBI homepage using the link on the lab webpage, or by going to: http://www.ncbi.nlm.nih.gov Select “Gene” from the database pulldown menu. Type “PTGS” in the search box, then click “Go.” Scan the results for the “Homo sapiens” entries. There should be one called “PTGS1” and one called “PTGS2.” Select each entry by clicking on its name, then read the paragraph under the “Summary” section for each entry. The drug Celebrex selectively inhibits PTGS2 while aspirin and other NSAID’s inhibit both PTGS1 and PTGS2 in the same way. Why do you think researchers wanted to discover a selective inhibitor to PTGS2? 2. Describe how studying 3-D structures of PTGS1 and PTGS2 could help researchers design a drug that binds to PTGS1, but not to PTGS2.
Go to the NCBI’s website at https://ncbi.nlm.nih.gov On the database dropdown menu, select “Gene” and search for “RB1.” The first entry should be on the Homo sapiens version; click the gene name. Use the information to answer the following: Go back to the RefSeq (back click once) section in the Gene Database entry for RB1. Click on “NP_000312.2” to access the protein’s amino acid acid sequence information: How many amino acids make up the RB protein? Does this value match your prediction in part d.ii.3? Scroll down to “Features.” List two examples of post-translational modifications that can happen to the RB protein
Which of the following is not a reason we often perform metagenomics studies by doing PCR using long degenerate primers for the 16S gene? Eliminates issue of having to randomly fragment DNA for sequencing (which can sometimes be tricky to optimize) All microorganisms have a 16S gene It is taxonomically informative and allows you to identify taxa using a database You can estimate relative taxa abundance by relative read abundance, avoiding genome size bias. You can make a phylogeny allowing you to do diversity analyses 16S has conserved regions and the primers used allow for some sequence variation, so we can amplify the region from different taxa efficiently using PCR
An ancestral gene "Stacin" is involved in initiating parental care in both males and females. The stacin gene duplicates and mutations arise in both copies that change the function. One copy becomes specialized to function in male parental care "Patristacin" and the other copy becomes specialized to function in female parental care "Matristacin". Which of the following terms best describes this change in function in the two sequences? Group of answer choices Profunctionalization Prefunctionalization Subfunctionalization Neofunctionalization
What is the program Finch TV used for? Viewing next generation sequencing data Opening sequencing files with the .bam file extension Opening sanger sequencing files with the .ab1 file extension Opening NGS files with the .ab1 file extension
DNA fingerprinting involves using restriction enzymes to cut DNA at a specific sequence, resulting in many fragments of different lengths. Gel electrophoresis then separates the fragments according to size. DNA fingerprints produced from four different individuals is shown below.The DNA for Individuals 3 and 4 could NOT be Select one: a. mitochondrial DNA from two people who have the same maternal grandmother (both their mothers had the same mother) b. mitochondrial DNA from two people who have the same paternal grandmother (both their fathers had the same mother) c. nuclear DNA from identical twins d. nuclear DNA isolated from a hair left at a crime scene and a buccal swab from a suspect who was present at the crime
The CRISPR-CAS system Choose an answer below: enables an adaptive immune response in bacterial cells against virus infections. is used by researchers to introduce targeted disruptions of genes in mammalian genomes. can be used for gene correction by homologous recombination. targets a specific DNA sequence with a complementary RNA molecule. all of the above
Identify the technology portrayed by the examples that follow Starting 1998, Apligraf, an engineered artificial skin has been used to replace the traditional skin grafts. The first bird genome to be sequenced is that of the chicken, Gallus gallus. It was completed in February, 2004. This databank has been useful in the study of human diseases transmitted from birds such as the Avian flus.
