The organism which gets hunted or killed is termed as prey, for example, the insect is prey in this case.
Answer:
RNA polymerase
Explanation:
The RNA polymerase is an enzyme used in the transcription of genes in DNA to make mRNA. RNA polymerase binds on the promoter region based on the sequences that can be identified by the enzyme’s active site. A mutation can distort the interaction between the promoter region and the enzyme’s active site hence throttle up or inhibit transcription.
