In the initial step of EM algorithm, the 20-residue-long binding motif patterns in each sequence are aligned as an initial guess of the motif.

In the initial step of EM algorithm, the 20-residue-long binding motif patterns in each sequence are aligned as an initial guess of the motif. Correct Answer True

The base composition of each column in the aligned patterns is then determined. The composition of the flanking sequence on each side of the site provides the surrounding base or amino acid composition for comparison. Each sequence is assumed to be the same length and to be aligned by the ends.

In EM algorithm, as an example, suppose that there are 10 DNA sequences having very little similarity with each other, each about 100 nucleotides long and thought to contain a binding site near the middle 20 residues, based on biochemical and genetic evidence. the following steps would be used by the EM algorithm to find the most probable location of the binding sites in each of the ______ sequences.
Refer to the figure given below. AB, CD and EF are three parallel paths. A person starts from AB to reach EF by moving in four steps - moving from AB to O1 in step 1, from O1 to CD in step 2, from CD to O2 in step 3 and from O2 to EF in step 4. If he takes a curved path in one step, he cannot take a curved path in the next step. In how many ways the person can reach EF from AB?
In a lake, there are 10 steps labelled using alphabets from A to J. Starting from step A, every minute a frog jumps to the 4th step from where it started - that is from the step A it would go to the step E and from E it would go to the step I and from I it would go to C etc. Where would the frog be at the 60th minute if it starts at the step A ?
