WU-BLAST

C

BLAST

D

FASTA

You are the administrator of a SQL Server 2000 computer. The server contains a database named FinanceData that is used by a client/server application. Each employee has a SQL Server login that the application uses to access the server.Your company hires a new employee named Andrew. You create a SQL Server login named Andrew. You also create a database user named Andrew in the database and grant the database user full permissions in the database.Whenever Andrew runs the client/server application, he receives the following error message: "Invalid object name." Andrew also reports that he cannot access the database by using the application.You need to ensure that Andrew can use the application. Which Transact-SQL statement should you execute?

A

EXEC sp_defaultdb 'Andrew','FinanceData'

B

GRANT ALL ON FinanceData TO Andrew

C

EXEC sp_addlogin 'Andrew'

D

EXEC sp_grantdbaccess 'FinanceData','Andrew'GOsp_addrolemember 'db_datareader','Andrew'

In protein/domain analysis, each protein in the predicted proteome is again used as a query of a curated protein sequence database such as ____ in order to locate similar domains and sequences. To find orthologs, very low E value scores (E<10<20) for the alignment score and an alignment that includes 60–80% of the query sequence are generally required in order to avoid matches to paralogs.

A

PubChem

B

Genbank

C

MeSH

D

SwissProt

Phytase, an enzyme produced by Aspergillus niger can be adsorbed on microcrystalline cellulose powder (MCCP). The adsorption follows a Langmuir isotherm and the maximum concentration of the protein that can be obtained on the adsorbent is 70 mg cm^-1. At a concentration of 50 mg L^-1 of protein in the solution, the concentration of protein on the adsorbent reaches 35 mg cm^-1. It is desired to recover 90% of the protein from 1.5 liter of the cell free culture filtrate containing 220 mg L^-1 protein by addition of MCCP to the solution. The concentration of the protein adsorbed on the solid at equilibrium will be:

A

21.4 mg cm-3

B

214 mg cm-3

C

2.14 mg cm-3

D

None of the above

Directions : In each of the following questions a statement is given, followed by two conclusions. Give answer :

Statements : About 50 per cent of the animal by-products - hair, skin, horns etc. is edible protein. American chemists have developed a method of isolating 45 per cent of this protein. They used an enzyme developed in Japan to break down soya protein.

Conclusions :
I. Americans have not been able to develop enzymes.
II. Animal by-products protein has the same composition as soya protein.

A

Only conclusion I follows

B

Only conclusion II follows

C

Either I or II follows

D

Neither I nor II follows

E

Both I and II follow
