Question

In Organization of the GenBank database and the search procedure used by ENTREZ—each row is another sequence entry and each column another GenBank field.

(a) True

(b) False

This question was posed to me in an interview for job.

Question is taken from Sequence Formats & Computer Storage of Sequences in chapter Collecting & Storing Sequences in Laboratory of Bioinformatics

Answer 1

Right option is (a) True

To explain I would say: When one sequence entry is retrieved, all of these fields will be displayed. Search for the term “SOS regulon and coli” in all fields will find two matching sequences. Finding these sequences is simple because indexes have been made listing all of the sequences that have any given term, one index for each field. Similarly, a search for transcriptional regulator will find three sequences.
