Which case best fits the description of functional genomics?
A) Collecting sequence data of bacteria from various soil samples to examine how the presence of nematodes affects bacterial diversity
B) Collecting sequence data of the microbiome from the stools of people with irritable bowel syndrome and healthy controls
C) Examining the sequences of bacteria that live inside aphids compared with free-living bacteria
D) Examining the genomes of domesticated animals compared with their nondomesticated relatives to look for genomic signatures of domestication
E) Examining which sequences in genomes are involved in regulation of transcriptional activity

Question

Quizplus · Accepted Answer

Functional genomics involves studying the functions of genes and their interactions in a genome. Examining which sequences in genomes are involved in the regulation of transcriptional activity falls under this definition. Therefore, option E is the best choice for functional genomics. The other options involve studying the diversity of genomes, microbiota, or the genetic changes that occurred during evolution, but they do not necessarily focus on gene function and interaction.
