Question

FASTA format contains

• A. Only sequence
• B. Only annotation
• C. Header line and sequence
• D. Alignment scores

Hint:

Basic FASTA format: \[ \boxed{ \begin{array}{l} >\text{Sequence identifier} \text{ATGCGATCGATCG\ldots} \end{array} } \] The first line is the header, and the remaining lines contain the biological sequence.

Answer 1

The Correct Option is C

Step 1: Recall the FASTA format. A FASTA file begins with a header line starting with the symbol \[ \boxed{>} \] followed by an identifier or description.

Step 2: Identify the remaining content. The header is followed by the nucleotide or protein sequence. Thus, a FASTA file contains \[ \boxed{\text{Header line and sequence}.} \] Therefore, \[ \boxed{(C)} \] is the correct answer.
