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...

CMMB Tutorial Quiz 1WISH - correct answer Whole-mount Insitu Hybridization -> involves staining whole embryos with complementary RNA probe with label (DIG). Probe is detecting using anti-DIG antibody. *Causes embryos to shrink B-Galactosidase/LacZ reporter assay - correct answer Dna containing enhancer, promoter and reporter injected into embryo creating a transgenic animal.

OSMT Exam Questions with verified Solutions 100% Solved 2024 Why doesn't phylogenetic systematics have a fixed number of hierarchical categories like Linnaean systematics? - answerEach branching point is a hierarchical level in the nested structure of phylogenetic systematics. The number of branching points—and therefore the number of possible hierarchical levels—varies substantially from one lineage to another. What aspect of evolution does phylogenetic systematics represent more cle...
