Evolution as a process Microevolution: changes in allele frequencies. Observing change at the level of the gene Evolution as a pattern Macroevolution: descent with modification. Proven with fossil records, anatomical comparison 3 Requirements for Natural Selection Variation, heritability, and differences in fitness (survival/reproduction). ONLY EVOLUTIONARY FORCE THAT LEADS TO ADAPTATION Evidence for Evolution 1.Direct observation of evolutionary change 2.Homology 3.Fossil Record Homology Si...

CPPS 325 FINAL EXAM QUESTIONS WITH COMPLETE SOLUTIONS What is src? - Answer-Src is a non-receptor TK, so it does not span a membrane. It is a tyrosine kinase. And although it is cytoplasmic TK it can still bind to activated RTKs. What is contact inhibition confluency? - Answer-Stops Src domains signalling and therefore cells stop dividing. If there is an issue then cancer can result and mutation causes an inhibition of the stop signal so the cells keep growing and dividing. What are...

BIO 148 EXAM2 PRACTICE TEST 63 Questions with Verified Answers . A doctor is trying to identify the mutant gene that causes her patient to be colorblind. To do this she takes a swab of the patient's cheek cells to send off for DNA sequencing. Did she sample the correct cells? a. No, because the cells of the eye have different genes than the cells of the cheek. b. No, because the cells of the eye have different chromosomes than the cells of the cheek. c. Yes, because both cells have the s...
