Use figure 2 to answer this question The model shown in figure two can best be used to explain to answer to which question
A. what happens when an activator protein binds to the working enhancer in a strand of DNA
B. When a coding region of a gene becomes inactive is the deactivation of the enhance of proteins the only cause
C. Why did some individuals develop the Mutation of the disrupts a working enchaner
D. when working a enhancer binds to a gene does it aect the amount of protein that can be produced

You will create a molecular clock model for an arthropod gene. follow these guidelines to make your model: . your timeline will span from 90 million years ago to the present. the common ancestor in your model is an arthropod that lived 90 million years ago. the gene that you'll track codes for a protein in the species venom . the dna sequence youll track contains 10 nitrogen bases. you can choose the order of the bases and where the mutations occur. this gene mutates at a rate of approximately 0.76 base pairs every 17.1 million years. to build your model,/ calculate the estimated time period it takes for 1 base pair to mutate. the first time period will only show the common ancestor. at the beginning of the second time period, three lineages will diverge from the common ancestor, each with a different mutation in their gene sequences. the first and third descendant species will survive for the rest of the timeline. the second descendant species was extinct 50 million years ago. calculate how long it will take for one full base pair mutation to occur. explain your reasoning by constructing a mathematical equation
