Bio 202 EXAM 3 QUESTIONS AND CORRECT DETAILED ANSWERS How is recombinant DNA technology used to clone the human GH gene? 1st step! - ANSWER 1. use PCR to obtain the gene (Simply cutting the DNA with restriction enzymes would not be an effective way to isolate a specific gene. The genome would be cut into so many fragments, if you ran a gel it would be a smear! Which fragment is yours? You would need hybridization to isolate your fragment. Wouldn't have much DNA- not like the amo...

CMMB 343 FinalHow does phi6 penetrate the host cell? - correct answer - because it is an enveloped phage, it uses the entry and uncoating model that relies upon spike-protein mediated endocytosis - once in the vesicles, it releases the viral particles and proteases digest the capsid coat, lysing the vesicle, and releasing the phage genome into the cytoplasm Which protein is the plug at the end of the tail tube in T4, preventing DNA from leaving the tail tube to enter the host? - correct a...
