Q54.
Which of the following is incorrect about ENTREZ?

a.

There is no simple way to find the correct sequence without manually checking the information provided in each sequence, but this usually takes longer time

b.

Before leaving ENTREZ, it is often useful to check for sequence database entries that are similar to the one of interest, called “neighbors” by ENTREZ

c.

The expanded query searches other database entries of interest, such as the same protein in another organism, a large chromosomal sequence that includes the gene, or members of the same gene family

d.

While visiting the site, note that ENTREZ has been adapted to search through a number of other biological databases, and also through Medline, and these searches are available from the initial ENTREZ Web page

Answer: (a).There is no simple way to find the correct sequence without manually checking the information provided in each sequence, but this usually takes longer time
Q55.
Which of the following is incorrect about Retrieving a Specific Sequence?

a.

It can be difficult to retrieve the sequence of a specific gene or protein simply because of the sheer number of sequences in the Gen-Bank database and the complex problem of indexing them

b.

Other projects may benefit from the availability of better curated and annotated protein sequence databases, but not PIR and SwissProt

c.

For projects that require the most currently available sequences, the NR databases should be searched

d.

The genomic databases can also provide the sequence of a particular gene or protein. Protein sequences in the Genpro database are generated by automatic translation of DNA sequences

Discuss
Answer: (b).Other projects may benefit from the availability of better curated and annotated protein sequence databases, but not PIR and SwissProt
