Question

Which of the given statements is incorrect?

(a) Before using a sequence file in a sequence analysis program, it is important to ensure that computer sequence files contain only sequence characters and not special characters used by text editors

(b) Computer sequence files might contain special characters used by text editors

(c) Editing a sequence file with a word processor can introduce such changes if one is not careful to work only with text or so-called ASCII files

(d) Most text editors normally create text files that include control characters in addition to standard ASCII characters

I have been asked this question by my school teacher while I was bunking the class.

I'd like to ask this question from Sequence Formats & Computer Storage of Sequences topic in chapter Collecting & Storing Sequences in Laboratory of Bioinformatics

Answer 1

The incorrect statement is:

(d) Most text editors normally create text files that include control characters in addition to standard ASCII characters.

Most basic text editors (like Notepad or simple text editors) create plain text files that generally only include standard ASCII characters and do not typically introduce control characters unless the user specifically inserts them (such as for formatting purposes in word processing programs). Control characters are not typically part of standard text files unless the file has been processed or saved in a format that includes them (like rich text formats). Therefore, statement (d) is incorrect, as it implies most text editors add control characters by default, which is not the case for plain text files.
