Question 81. Which of the given statements is incorrect about Block multiple sequence alignment format?

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
The identifier is terminated by a comma, and “BLOCK” indicates the entry type
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
The block number is a 5-digit number preceded by BL (BLOCKS database) or PR (PRINTS database)

Discuss Question

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

Question 87. Each DNA or protein sequence database entry has much information, including ______

an assigned accession number(s)
source organism
name of locus
reference number type(s)

Discuss Question

Answer: Option D. -> reference number type(s)
Answer: (d).reference number type(s)

Question 88. Which of the following is an incorrect statement?

The last column contains the sequences themselves
It is quite tough making an index of the information in each of these fields so that a search query can locate all the occurrences through the index
If one imagines a large table with each sequence entry occupying one row, then each column will include one of the above types of information for each sequence, and each column is called a FIELD
The DNA, protein, and reference databases have all been cross-referenced so that moving between them is readily accomplished

Discuss Question

Answer: Option B. -> It is quite tough making an index of the information in each of these fields so that a search query can locate all the occurrences through the index
Answer: (b).It is quite tough making an index of the information in each of these fields so that a search query can locate all the occurrences through the index

Question 89. Which of the given statements is incorrect about Database Types?

Relational databases are more useful in the development of biological databases
The tables in relational database are carefully indexed and cross-referenced with each other, sometimes using additional tables, so that each item in the database has a unique set of identifying features
The relational database orders data in tables made up of rows giving specific items in the database, and columns giving the features as attributes of those items
The two principal types of DBs are the relational and object-oriented databases

Discuss Question

Answer: Option A. -> Relational databases are more useful in the development of biological databases
Answer: (a).Relational databases are more useful in the development of biological databases

Question 90. The FASTA format is readily converted into other formats and also is smaller and simpler.
