QUESTION 10 points Save Answer Given the following alignment in context of motif finding problem, what is the consensus sequence? cggtacct ccatacgt ccattagt acatgcct ccatacgg ccataogt ecttacgt ccatacg caataogt QUESTION 2 10 points Save Answer Instead of four bases, let's assume that 6 bases are needed for constructing DNA. In this case, how many leaf nodes will be there in the tree that stores all possible 2-mers ? 64 16 QUESTION 3 10 points Save Answer Given DNA as the following two sequences in the context of Median String Finding Problem, ccatacg ccattag Which of the following 4-mer has the lowest value of TotalDistance(v,DNA) ? QUESTION 4 10 points Save Answer which of the 16 possible 2-mers has the highest value of totalDistance(v,DNA) from the DNA sequence ? cetgatagacgctatetggctatcc gc

Explanation / Answer

Answer. 1. The consensus sequence is determined by taking the how frequently the base is there. In this case if I align then comparing first base "C" is most common then again "C" then "a" as. such the answer is "ccatacgt"

Answer. 2 if 2 mer is on last and assumed bases in DNA are 6 then possibility is 26 i.e 64. So answer is 64.

Answer 3. Lowest value of total distance (v, DNA) can be obtained by aligning here in case of ccaa three matches which shows lowest total distance (v, DNA) so answer is "ccaa".

Answer 4. Highest value of total distance is "GC" as it come two times but cc also come two time but we can not consider it as cc occurs on starting of sequence.
