Draw the E-R diagram for the database of a departmental
store having the following relational database scheme
Employees(e-no, address)
Department(d-name)
work-n(e-no, d-name)
Looking-after(d-name, e-no)
Item (item-no, brand-name, model-no, cost-price, sale-price)
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?
Which of the following sequences contains the pattern [AG]-x
(4)-G-K-[ST] from the PROSITE database?
seq. A: VAGWGKST
seq B: GVLKRGKS
seq. C: AGVLKGRT
seq. D: AGVGKSTP
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?

(2x-1)(2x-3)(2x-5)(2x-7)=9?
