Bio 203 exam 4 - Study guides, Class notes & Summaries

Bio 203 Exam 4 practice test questions & answers (100% Correct) What is the reason that closely linked genes are typically inherited together? The likelihood of a crossover event between these two genes is low All female mammals have one active X chromosome per cell instead of two. What causes this? Activation of the XIST gene on the X chromosome that will become the Barr body In his transformation experiments, what did Griffith observe? Mixing a heat-killing pathogenic strain of bacteri...

How did evidence from the study of metabolic defects contribute to the fundamental relationship between genes and proteins? - ANSWER -Garrod suggested that genes dictate phenotypes through enzymes that catalyze specific chemical reactions -Symptoms of an inherited disease reflected inability to synthesize a certain enzyme. -Linking genes to enzymes required understanding that cells synthesize and degrade molecules in a series of steps called the metabolic pathway. Describe the experiment by...
