What are the characteristics of the most highly expressed genes in the ocean? How abundant are they in microbial genomes (across all microbes) and what sorts of metabolic processes are they involved in?
What will be an ideal response?
The most highly expressed DNA sequences in the open ocean are microbial genes that happen to be most rare in microbial genomes. They include elements of photosynthesis (light harvesting proteins and Rubisco) and genes for DNA repair (likely due to UV damage).
