If we have the assumption that the residues at individual positions in a family of DNA sequences are independent and have the identical probabilities, what would be the maximum likelihood estimates (MLE) of the probabilities of having different bases at each residue in this family: P(A), P(G), P(C), and P(T) if we have already known that the following five sequences belong to this family? P(A) = 0.03, P(G)=0.6, P(C) = 0.3, P(T)=0.07

We consider two DNA sequences with the letters A; G; T; and C. Suppose that the letters on different locations are independent with probability P[A] = P[G] = P[C] = 2 and P[T) = }. The sequences both have infinite length (here we idealized of course..) and the two sequences are independent. When the letters are read by a sequence processor an error is made with probability 10-4. Whenever an error is made, the 'wrong' letters are read with equal...

Return to the original model. We now introduce a Poisson intensity parameter X for every time point and denote the parameter () that gives the canonical exponential family representation as above by θ, . We choose to employ a linear model connecting the time points t with the canonical parameter of the Poisson distribution above, i.e., n other words, we choose a generalized linear model with Poisson distribution and its canonical link function. That also means that conditioned on t,...

Assume that we have three independent observations: where Xi ~ Binomial(n 7,p) for i E { 1.2.3). The value of p E (0, 1) is not known. When we have observations like this from different, independent ran- dom variables, we can find joint probabilities by multiplying together th ndividual probabilities. For example This should remind you the discussion on statistical independence of random variables that can be found in the course book (see page 22) Answer the following questions a...

The big idea behind hypothesis testing is that we have an assumption about reality, and we see if the data fits that assumption. The whole process gets complicated by all the notation and calculations, but essentially we’re deciding if the assumption is possible, or if the data leads us to reject it. 1.

Question 33 2 pts Which of the following statements about the process of DNA replication is true? It involves the enzyme DNA ligase, which corrects point mutations. It utilizes DNA polymerase, which catalyzes the reaction that adds a new nucleotide to the growing strand. The sequence on the new strand is always identical to one of the old parent strands. Adenine pairs with guanine, and cytosine pairs with thymine. Question 34 2 pts The DNA base...
