Q21.
Which of the following is wrong about GenBank DNA Sequence Entry?

a.

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

b.

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

c.

Some identifiers may have additional subfields

d.

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

Discuss
Answer: (d).The CDS subfield in the field FEATURES does not offer the amino acid sequence
Q22.
A consecutive set of three-letter words that could be codons specifying the amino acid sequence of a protein. The sequence entry is assumed by computer programs to lie between the identifiers “ORIGIN” and “//”.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True
Q23.
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

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True
Q24.
Which of the following is wrong about European Molecular Biology Laboratory Data Library Format?

a.

EMBL maintains DNA and protein sequence databases

b.

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

c.

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

d.

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

Discuss
Answer: (c).Sequence entry includes literature references and information about the function of the sequence, but not locations of mRNAs and coding regions
Q25.
The format of an entry in the SwissProt protein sequence database is very similar to the EMBL format.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True
Q26.
Which of the following is wrong about FASTA Sequence Format?

a.

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

b.

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

c.

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

d.

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

Discuss
Answer: (d).The presence of ‘*’ is not quite essential for reading the sequence correctly by some sequence analysis programs
Q27.
Which of the following is wrong about National Biomedical Research Foundation/Protein Information Resource Sequence Format?

a.

Sequences retrieved from the PIR database are not in this compact format, but in an expanded format with much more information about the sequence

b.

The NBRF format is similar to the FASTA sequence format but with significant differences

c.

This is different than PIR format

d.

The first line includes an initial “>” character followed by a two-letter code such as P for complete sequence or F for fragment, followed by a 1 or 2 to indicate type of sequence, then a semicolon, then a four- to six-character unique name for the entry

Discuss
Answer: (c).This is different than PIR format
Q28.
In Stanford University/Intelligenetics Sequence Format At the end of the sequence, a 1 is placed if the sequence is linear, and a 2 if the sequence is circular.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True
Q29.
Which of the following is wrong about Genetics Computer Group Sequence Format?

a.

Earlier versions of the Genetics Computer Group (GCG) programs require a unique sequence format and include programs that convert other sequence formats into GCG format

b.

Information about the sequence in the GenBank entry is not included but the line information is carried out

c.

If one or more sequence characters become changed through error, a program reading the sequence will be able to determine that the change has occurred because the checksum value in the sequence entry will no longer be correct

d.

Lines of information are terminated by two periods, which mark the end of information and the start of the sequence on the next line

Discuss
Answer: (b).Information about the sequence in the GenBank entry is not included but the line information is carried out
Q30.
Which of the following is wrong about Abstract Syntax Notation Sequence Format?

a.

The information is much more difficult to read by eye than a GenBank formatted sequence

b.

Abstract Syntax Notation (ASN.1) is a formal data description language that has been developed by the computer industry

c.

All the information found in other forms of sequence storage, e.g., the GenBank format, is present. For example, sequences can be retrieved in this format by ENTREZ

d.

Taxonomic information and bibliographic information cannot be encoded with this format

Discuss
Answer: (d).Taxonomic information and bibliographic information cannot be encoded with this format
