The phrase "a pool of organisms" is correct and usable in written English.
It can be used in contexts related to biology, ecology, or discussions about biodiversity, referring to a group or collection of different organisms in a specific area.
Example: "The researchers discovered a pool of organisms thriving in the newly formed wetland, showcasing a diverse range of species."
Alternatives: "a collection of organisms" or "a group of organisms".
If the ancestor was a pool of organisms as Dr. Woese suggests, and not a definable species, it may be even harder to capture its likeness.
Recent experiments in metagenomics (also known as community genomics or environmental genomics) have proposed that genetic sequences from previously uncatagologued species can be discovered/recovered and investigated by subjecting large samples of RNA or DNA taken from a pool of organisms representative of a set of different species to shotgun sequencing and assembly [1] [7].
In the second we design an experiment in which the goal is to obtain appropriately sized contigs simultaneously from each of a large (but specified) number of novel species of equal genome size and representation in a pool of organisms containing no known species.
One challenge when screening an unknown pool of organisms for biological activity is capturing the greatest variation in a reasonable number of samples.
Genomes of the major microbial model organisms have been sequenced, some multiple times; projects to sequence new genomes will select from a pool of increasingly obscure organisms.
This suggests that a pool of partial persists organisms persist long after withdrawal of selective pressure at a relatively constant proportion.
Our results show that selective pressure is likely to result in resistance with respect to the selective pressure and a pool of partial resistant organisms is likely to persist long after withdrawal of selective pressure.
RNA was extracted from each replicate, which contained a pool of 20 and 40 organisms, for soil and water exposure, respectively.
This procedure is based on the optimization model that Kumar and Maranas [ 39] developed to resolve FP inconsistencies in the E. coli metabolic network by adding a minimum number of reactions from a pool of reactions collected from multi-organism databases (MetaCyc [ 43] and KEGG [ 44]).
However, it remains unclear whether or not the symbionts were repopulated from the standing intracellular pool of organisms or reacquired from the environment.
The remainder of any given E. coli bacterium's genome is drawn from a pool of about 20,000 other genes that the organisms swap with gay abandon.
