A biologist who is trying to find open reading frames in a section of DNA is working in the field of
A) functional genomics.
B) comparative genomics.
C) metagenomics.
D) biodiversity.
E) proteomics.

Question

Quizplus · Accepted Answer

The identification of open reading frames (ORFs) in DNA is a key step in functional genomics, which aims to understand how genes function and interact to produce biological traits and disease states. Comparative genomics compares genome sequences across different species or groups to identify similarities and differences in gene structure, function, and evolution. Metagenomics studies the genomes of microbial communities found in environmental samples, such as soil or water. Biodiversity is the study of the variation of life forms within a given ecosystem, while proteomics is the study of the structure and function of proteins. While each of these fields may involve the analysis of DNA, the specific task of finding open reading frames is most closely associated with functional genomics.
