Information within sequence databases, such as GenBank, could be used to perform which of the following tasks?
A) Determine the expression pattern for specific human genes.
B) Construct a tree to determine the evolutionary relationships between various bird species.
C) Search for genes that have not yet been identified in eukaryotic genomes.
D) Compare patterns of gene expression in cancerous and non-cancerous cells.

Question

Quizplus · Accepted Answer

Sequence databases like GenBank store nucleotide sequences and their annotations. These databases can be used to compare sequences across different species, which is essential for constructing phylogenetic trees to determine evolutionary relationships, as described in option B. Other tasks listed involve gene expression analysis, which typically requires additional data types and methods beyond sequence databases.
