The rapidity and cost-efficiency of DNA sequencing has made it possible to sequence virtually all of the genes present in the microbes of a given habitat. This generates a collective genome for that habitat, which has come to be called _________.
A)a metachron
B)a metagenome
C)a netagenome
D)a megagene
E)an exogenome

The term used to describe the collective genome of all the microbes present in a given habitat is a "metagenome". This term is derived from "meta-" meaning "beyond" or "transcending", and "genome" referring to the complete set of genes that an organism possesses. Therefore, the best choice is B, "a metagenome". The other answer choices are not accurate or appropriate descriptions for this concept.
