Question Answered step-by-step Accessing DNA Sequence Data from Large DatabasesLearning… Accessing DNA Sequence Data from Large DatabasesLearning objectives:Students can explain how different technologies are used to identify genomic differences within and across species.Students apply their understanding of genetics and bioinformatics to address human health and disease. IntroductionIn this week’s lab you’ll do a case study where you are provided information regarding the disease symptoms of a patient and investigate how blood tests are used to isolate viruses and bacteria. Many tests for viruses search for a particular protein on the surface of the virus, called an antigen, called the N protein. During lab, you’ll learn more about this particular protein and other viral antigens. Gene sequencing allows scientists to determine the order of base pairs in a segment of DNA or RNA. You’ll be using the NCBI Database to access and compare DNA sequences. Watch the tutorial below so you are prepared for using this technology during lab: https://app.vidgrid.com/view/AaVKpBVm3WwL/?sr=uPdHqa Recall from the Central Dogma lab that proteins are the product of transcription and translation. Viruses, in the most basic sense, are not much more than capsules of nucleic acids that use the host cell’s transcription and/or translation machinery to replicate and produce the viral proteins. Here’s the shaded Box code:What might occur when there is a mutation in the gene that codes for the N-protein? What factors do y0u predict might influence the likelihood of mutations occurring in viruses? After watching the tutorial video note how many sequences are found from the database. NCBI pulls from multiple databases and there are currently more than 1 trillion sequences in the database! What are some other significant uses you can think of for utilizing a large database of DNA sequences?      Biology Science cell biology BIO 101L Share QuestionEmailCopy link Comments (0)
