Which of the following is the protein structure databases

• SWISS-PROT

• GenBank

• PDB

• DDBJ

BankIt and Sequin are sequence submission tools at

• DDBJ

• PIR

• EMBL

• GenBank

Which of the following are the sequence retrieval system of EMBL

• Entrez

• Saqura

• SRS

• BankIt

The information retrieval system at NCBI is

• Entrez

• Prosite

• SRS

• STAG

Knowing ________ should be enough to find the required entry quickly.

• publication date, protein name, journal name

• accession number, protein name, or name of gene

• publication date, protein name, or volume

• publication date, protein name, or volume

Which of the given statements is incorrect about Database Types?

• Relational databases are more useful in the development of biological databases

• The tables in relational database are carefully indexed and cross-referenced with each other, sometimes using additional tables, so that each item in the database has a unique set of identifying features

• The relational database orders data in tables made up of rows giving specific items in the database, and columns giving the features as attributes of those items

• The two principal types of DBs are the relational and object-oriented databases

Which of the following is wrong about GenBank DNA Sequence Entry?

• The information is organized into fields, each with an identifier, shown as the first text on each line

• In some entries, these identifiers may be abbreviated to two letters, e.g., RF for reference

• Some identifiers may have additional subfields

• The CDS subfield in the field FEATURES does not offer the amino acid sequence

Which of the following is wrong about European Molecular Biology Laboratory Data Library Format?

• EMBL maintains DNA and protein sequence databases

• As with GenBank entries, a large amount of information describing each sequence entry is given

• Sequence entry includes literature references and information about the function of the sequence, but not locations of mRNAs and coding regions

• Information is organized into fields, each with an identifier, shown as the first text on each line

Which of the following is wrong about FASTA Sequence Format?

• The FASTA sequence format includes a comment line identified by a “>” character in the first column followed by the name and origin of the sequence

• The FASTA sequence format includes the sequence in standard one-letter symbols

• This format provides a very convenient way to copy just the sequence part from one window to another because there are no numbers or other nonsequence characters within the sequence

• The presence of ‘*’ is not quite essential for reading the sequence correctly by some sequence analysis programs

SCOP is

• it is primary database

• it is nucleotide sequence database

• SCOP database is ahierarachial classification of protein 2D domain structures

• structural databse, which identity strual and evolutionary relationships
