Place the steps of generating a gene - knockout mouse in order from the dis- ruption of the target gene to generat- ing homozygous knockouts. Suppose in 1. Disrupt target gene by insert- ing neo+ and link tk+ to disrupted gene 2. transfer disrupted gene into one experiment, the stem cells used are stem cells from a black mouse from a black coated mouse, and the earl3y. allow recombination with mouse embryo ...

Explain how auxotrophic mutants can be isolated and how they inform us about metabolic pathways CORRECT ANSWER - screen for mutations in prototrophs (an organism capable of synthesizing all its metabolites from inorganic material) that cause them to become auxotrophic for a certain metabolite - map the mutation to a particular enzyme, then match enzyme to metabolic pathway - accumulations of the intermediate made before the blocked pathway help us piece together the biosynthetic pathways p...

Primavera Biology B Unit 3: Genomics (2023/2024) Already Graded A CHECKPOINT 12 Genes located close together on a chromosome tend to be inherited together. What is this called? genetic linkage Which of the following genes are linked in pea plants? flower color and pollen-grain shape A Punnett square incorrectly predicts the outcome of a dihybrid cross. There are only two phenotypes in the F2 offspring instead of four. Why? The genes are completely linked. A Punnett square predicts that the...
