If it killed the top level of an ecosystem it would damage the whole ecosystem because it's connected. An organism depends on that top organism which would mean that is that organism dies it would affect the organism that depends on it.
• Genes can contain more than one polyadenylation site, which alters the 3' of the mRNA transcript and the inclusion/exclusion of exons.
• mRNA transcripts from the same gene can be differentially spliced to include/exclude exons.
Using Natural predators to reduce insect numbers caused the least harm to the environment.
