Explain about needleman-wunsch algorithm?
What does the ultrametric property of a tree tell us about the evolutionary process?
What is the difference in terms of connectivity between a scale free network and random network?
What two possibilities are there to describe how gene fragments may have evolved?
Suppose you used the NCBI Blast server to look for a match to a fruit-fly gene. Suppose further that the best alignment contained this section of an alignment: Hit from database: XXXXXXXXXXXXXXNFSTSQ User sequence: SLEAEAAPASISPSNFSSSQ What do the Xs signify?
Suppose the Blast search returned 100 hits. Of these, 17 were false positives and we knew that there were 165 sequences in the database which should have returned a hit with our sequence. How many false negatives were there, and what is the sensitivity and selectivity of Blast in this instance?
What is the idea behind ?weighting? sequences in the package CLUSTAL W for multiple alignment? How are these weights calculated?
Integrate 3x + 5 / (x3-x2-x+1)?
An electron is injected into a region of uniform magnetic flux density with the components of velocity parallel to and normal to the flux. What is the path of the electron?
Define perl and clustalW problem?
What is C-compliator?
How to caculate coordinates of each atoms on 3 D HP model?
How to find coexpressed genes on NCBI GEO?
How to run DOCK 6 using cygwin?
Bootstrap analysis evaluates evolutionary trees by sampling columns from the original alignment with replacement (multiplying or removing some of them) and computing a proportion of times that a particular branch appears in the resulting trees. What is the main idea behind this approach?
