Question

Readseq one of the most popular computer programs written by Don Gilbert at Indiana University used for

• A. Molecular viewer
• B. Molecular file format conversion
• C. Sequence format conversion
• D. Fold and domain recognization

Hint:

Remember "Readseq" as "Read Sequence". Its job is to read a sequence in any format and allow you to save it in another. It's the Swiss Army knife for dealing with the zoo of bioinformatics sequence file formats.

Answer 1

The Correct Option is C

Step 1: Introduction:
Bioinformatics relies on various text-based file formats (FASTA, GenBank, etc.) to store biological sequence data (DNA, RNA, proteins). Different analysis tools require specific formats. Readseq is a widely used utility addressing this need.
Step 2: Functionality:
Readseq's primary role is to convert biological sequence files from one format to another. It's a sequence file format translator.
Let's consider the options:
Molecular viewer: This is for viewing 3D structures (e.g., PDB files). Readseq does not perform this function.
Molecular file format conversion: This is too broad. Readseq specifically handles sequence file conversion, not general "molecular files."
Sequence format conversion: This is precisely what Readseq does: converting biological sequences between different formats.
Fold and domain recognition: This involves complex algorithms for predicting protein structure or identifying functional domains (e.g., BLAST, HMMER). Readseq is a simpler utility.
Step 3: Conclusion:
Readseq is a program for converting biological sequence formats.
