Q31.
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

Discuss
Answer: (b).Computer sequence files might contain special characters used by text editors
Q32.
Which of the given statements is incorrect about ASCII and Hexadecimal?

a.

Computers store sequence information as simple rows of sequence characters called strings, which are similar to the sequences shown on the computer terminal

b.

Each character is stored in binary code in the smallest unit of memory, called a byte

c.

Each character is stored in binary code in the smallest unit of memory, called a bit

d.

By convention, many of these combinations have a specific definition, called their ASCII equivalent

Discuss
Answer: (b).Each character is stored in binary code in the smallest unit of memory, called a byte
Q33.
Which of the given statements is untrue?

a.

Sequence and other data files that contain non-ASCII characters also may not be transferred correctly from one machine to another and may cause unpredictable behavior of the communications software

b.

The ASCII mode is useful for transferring text files, and the binary mode is useful for transferring compressed data files, which also contain non-ASCII characters

c.

ASCII and binary modes cannot be set by the user

d.

Most sequence analysis programs also require not only that a DNA or protein sequence file be a standard ASCII file, but also that the file be in a particular format such as the FASTA format

Discuss
Answer: (b).The ASCII mode is useful for transferring text files, and the binary mode is useful for transferring compressed data files, which also contain non-ASCII characters

Answer: (a).True
Q36.
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)

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