    Genetic mutations are the source of numerous hereditary diseases. This has been discovered by the comparison of two DNA sequences with bioformatic software. Two sequences are aligned and compared in order to locate mutations in the DNA (Module 4 Protocol,1). Escherichia coli aka E. coli was used as the test subject in this lab because it employs lac operons while transcribing mRNA. An operon is a unit of linked genes that regulates genes in charge of protein synthesis. A lac operon requires the presence of lactose to function. E. coli will only transcribe mRNA for specific enzymes when a certain sugar is detected in the surrounding environment. Lac operons are made up of a CAP binding site, -35/-10 sites, operator region, the start site…

    Coli is used very commonly by other researchers and companies. Pharmaceutical companies use it to go drugs like insulin in large quantities to sell to the public. Researchers use it to invent most of the drugs that the pharmacy companies are using but also to see how other traits would act in different bacteria. Another procedure that could be done in the same manner as this one could be the LUX operon, which is the transcriptions of genes to create bioluminescent products (Swarztman, 1990).…

    Reflection Two Things I Didn’t Know The first thing I learned about the social work practice while at Mille Lacs County is that not all situations will play out how you want them to. Of course I knew that in a general sense; however, there were many situations that I was a part of and/or heard about at the county where things didn’t go down how they were expected to, wanted to, or maybe even should have. This job can be unpredictable with clients as well as with judges and that is something that…

Because of Mille Lacs residing in central Minnesota, Anglers cannot justify a long drive to only take a single fish home each day. However, increasing the limit allows local business to thrive with an influx of anglers spending at gas stations, bait shops, and guide services. We also see an increase in the overall fishing industry with extensive purchases of tackle and…

    Prokaryotes can be recognized as a single-celled organism that lack the extensive internal compartments. Unlike eukaryotes, the prokaryotes concentrated their genetic materials in a small portion of cell’s cytoplasm known as nucleoid. Almost entire prokaryotic genome is contained in a single circular DNA strand that is supercoiled. Some additional genes are located on an independent small, circular or linear plasmids which coding for extra properties likes antibiotic resistance (Brown, 2002).…

    Bacterial genes regularly found in operons. Genes in an operon were transcribing as a group. They have a particular promoter. One another operon consist regulatory sequence of DNA. This can act as binding site for regulatory proteins. They stimulate or inhibit the transcription. Regulatory proteins often bind to the minor molecules. Which able to make the protein active/ inactive. By varying the capability to bind DNA. Some operons are inducible. That they be able to turn on by the presence of…

    1. What are proinsulin and insulin? How different is proinsulin from insulin? A: Insulin is a polypeptide hormone, protein, that is produced by the beta-cells of the pancreas. Proinsulin is a single peptide chain that is a precursor to insulin. It is produced by the beta-cells of the pancreas as well. The structure of proinsulin differs from insulin in that it contains a C-chain that forms a single peptide chain with other chains A and B. Insulin does not contain the C-chain and the A and B…
