1. What is the primary purpose of accession numbers in biological databases?

To provide a complex coding system for data encryption.
To track and manage changes in biological data over time.
To categorize data based on the geographical location of its source.
To indicate the physical location of a sample in storage.

2. Which of the following best describes the role of primary databases in bioinformatics?

They store processed and interpreted data, such as protein domain structures.
They serve as foundational layers storing raw data from experimental outputs.
They are sophisticated visualization platforms integrating genomic information.

3. What is a major challenge in handling biological data as mentioned in the text?

The simplicity and uniformity of biological data.
The rapid and consistent format of biological data.
The significant diversity in size and type of biological data.
The decreasing volume of biological data over time.

4. Which of the following is a significant concern related to the interconnectedness of biological databases?

The speed of data retrieval becomes too fast to manage.
The spread of inaccuracies and errors through multiple databases.
The databases become too isolated and unable to communicate.
The data becomes too simple and lacks detail.
None of the above
All of the above

5. What distinguishes composite databases from primary and secondary databases?

They store only genetic information specific to diseases.
They provide raw, unprocessed data without any annotations.
They merge features of both primary and secondary databases, offering comprehensive data access.
They are used exclusively for storing information about protein structures.
