Question

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

This question was addressed to me in quiz.

The origin of the question is Sequence Formats & Computer Storage of Sequences topic in division Collecting & Storing Sequences in Laboratory of Bioinformatics

Answer 1

Right choice is (b) Information about the sequence in the GenBank entry is not included but the line information is carried out

The best I can explain: Information about the sequence in the GenBank entry is first included, followed by a line of information about the sequence and a checksum value. This value (not shown) is provided as a check on the accuracy of the sequence by the addition of the ASCII values of the sequence. If the sequence has not been changed, this value should stay the same.
