CMMB 403 Midterm 1 Question and answers already passed 2024Describe the RTK signal transduction pathway when activated by the FGF ligand FGF ligand dimerizes RTK receptor. Receptor is phorphorylated and attracts adaptor/GEF. GEF begins phosphorylation cascade: GEF to Ras to Raf to Mek to Erk to TF. TF transcribes gene Describe the JAK-STAT pathway when activated by FGF FGF ligand dimerizes RTK. JAK2 proteins cross-phosphorylate. Both JAK2s phosphorylate a STAT5 (which is a cytoplasmic tyr...

what does CRISPR use in order to generate changes in genome? is CRISPR forward or reverse genetics? - nuclease - 20 nucleotide RNA sequence to target specific sites in the genome - reverse genetics what is the role of Cas9 in CRISPR endonuclease that catalyzes double stranded breaks what are the two repair paths cells can use to repair double stranded breaks from CRISPR- Cas9 1. non-homologous end joining (NHEJ) - naturally try to repair - imperfect, creates indels causing frameshift mut...
