Biotechnology Chapter 6 Day 1 Questions Compare and contrast antigens and immunogens. Draw an antibody and label important parts. Describe the function of each part. Draw an antibody that has been digested with papain. How do the heavy and light chain fragments hold together following this cleavage event? When are DNA recombination and mRNA splicing … Continue reading B Cells and Antibodies

Biotechnology Chapter 5 Day 3 Questions How are snRNAs (snurps) involved in splicing? How does this differ from group II intron splicing?  What’s a lariat?  What’s a lariat structure? https://youtu.be/Dp_b9elTxdc Data from what method was used to identify many new alternative splice sites? How can an antisense therapeutic affect alternative splicing? Riboswitches are mostly found … Continue reading Artificial and Natural RNA Activities

Biotechnology Chapter 5 Day 2 Questions What are morpholinos? What would happen if you injected morpholinos into a frog egg? Discuss how siRNAs can “spread” systemically through a plant. What is PTGS? Describe miRNA maturation starting with transcription and ending with binding of an Argonaute protein to the target mRNA(s). A new category of RNA … Continue reading RNAi, PTGS, siRNA, miRNA, shRNA, but not piRNA…that was last time
