- A
Statistical visualization
- B
Sequence alignment
- C
Genome assembly

Database annotation
A researcher records the organism, tissue, and experimental method associated with a biological sample. This contextual information is .
A researcher needs to retrieve sequencing reads from a biological database. Which database listed in the material is designed for sequencing reads?
True or false: If two biological sequences are similar, that alone proves they share an ancestor.
- A
True
- B
False
A database record assigns a biological function to a protein, but the supporting evidence is unclear. What is the most responsible next step?
- A
Accept the function as certain because it appears in a database
- B
Discard the record because annotations can be incomplete
- C
Check the record's source, references, and supporting evidence
- D
Use the annotation without considering how it was produced

Important analysis parameters
A study measures RNA activity across several tissues and experimental conditions. What type of biological data are these measurements?
Genomics studies the full set of DNA in an organism, called its .
A researcher is studying an unfamiliar protein and wants computational clues about its possible function. What can protein sequence and structure tools help identify?
- A
Prove a protein's function without additional evidence
- B
Identify related proteins or conserved domains to support a function hypothesis

- A
SRA
- B
GenBank
- C
UniProt
- D
A database used only for genomic coordinates

A researcher has defined a biological question but has not yet obtained any data. According to the basic bioinformatics workflow, what should they do next?
- A
Share the analysis reproducibly
- B
Interpret the result in context
- C
Find or generate data
- D
Choose a computational method
A database record includes the organism, tissue, experimental method, and evidence supporting a functional claim. What is the main purpose of including this information?
- A
They replace the biological measurements with a summary.
- B
They provide context that helps users understand a sample or record.
- C
They prove that every functional claim in a record is certain.
- D
They convert all biological records into protein sequences.
If two biological sequences are similar, that similarity by itself proves that they have the same function.
- A
True
- B
False
