2.

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

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
Answer» 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
