Is the word "gene" a countable noun? I'm asking you this question to answer the problem below:
"Proponents argue that this particular strain is altered only by the removal of the gene responsible for the strain's propensity to cause frost damage, thereby rendering it safer than the phytopathogen from which it was derived."
Q) Is the statement below true or false?
The altered bacteria had a genetic constitution differing from that of the normal strain only in that the altered variety had one less gene.
It is confusing Because of the word "one" in the problem. If it says "gene" in the passage, does it mean one gene or could it be several genes?
