Applications of Bioinformatics

What are the key features of the GenBank database?

• Contains DNA, RNA, and genome sequences from different species.

• Provides annotations such as gene locations, functions, and protein translations.

• Works in collaboration with ENA and DDBJ to share global sequence data.

• All of the above.

What is the main function of the European Nucleotide Archive (ENA)?

• Stores nucleotide sequence data, including DNA and RNA.

• Provides easy-to-use submission tools for researchers.

• Enables retrieval of nucleotide sequences using keywords.

• All of the above.

What distinguishes primary databases from secondary databases in bioinformatics?

• Primary databases store original experimental results.

• Secondary databases store processed and curated data.

• Primary databases provide unprocessed data.

• All of the above.

What is the role of UniProt in bioinformatics?

• It is a primary database for nucleotide sequences.

• It provides detailed protein sequence and functional annotation data.

• It is a tool for sequence alignment.

• It stores raw sequencing reads.

What are the two key components of UniProt?

• Swiss-Prot and TrEMBL

• UniRef and InterPro

• Pfam and ENA

• DNA and RNA

What does a proteome refer to?

• The complete set of proteins expressed by an organism

• The complete set of DNA sequences in an organism

• The complete set of RNA sequences in an organism

• The complete set of genes in an organism

What is the purpose of UniRef?

• To organize protein sequences into clusters

• To provide a database of nucleotide sequences

• To classify proteins based on their functions

• To store raw protein data

What does InterPro provide?

• Functional classification of proteins

• A database of nucleotide sequences

• A collection of protein families

• A tool for sequence alignment

What is the main function of Pfam?

• To provide a collection of protein families and domains

• To classify DNA sequences

• To store raw protein data

• To provide a database of RNA sequences

What is sequence alignment?

• The process of arranging sequences to identify regions of similarity

• The process of translating nucleotide sequences

• The process of clustering protein sequences

• The process of annotating protein sequences
