Question

which of the given statements is incorrect about Block multiple sequence alignment format?

(a) Identification starts contain a short identifier for the group of sequences from which the block was made and often is the original Prosite group ID

(b) The identifier is terminated by a comma, and “BLOCK” indicates the entry type

(c) AC contains the block number, a seven-character group number for sequences from which the block was made, followed by a letter (A–Z) indicating the order of the block in the sequences

(d) The block number is a 5-digit number preceded by BL (BLOCKS database) or PR (PRINTS database)

The question was asked by my school principal while I was bunking the class.

My doubt stems from Multiple Sequence Formats & Storage of Information in a Sequence Database in chapter Collecting & Storing Sequences in Laboratory of Bioinformatics

Answer 1

Correct option is (b) The identifier is terminated by a comma, and “BLOCK” indicates the entry type

The best explanation: The identifier is terminated by a semicolon, and “BLOCK” indicates the entry type. Min, max is the minimum, maximum number of amino acids from the previous blocks or from the sequence starting. DE describes sequences from which the block was made.
