The protein-coding sequence of a gene doesn't matter much to determining what an animal looks like or how the gene functions. Regulatory genes such as promoters do that.

The AquAdvantage salmon is a genetically modified salmon. A growth hormone regulator from the chinook salmon and a promoter from an ocean pout were added to the Atlantic salmon. This enables them to grow year-round.

A Tyrannosaurus rex weighed between 6 and 7.5 tons, depending on the estimate. An African bush elephant can weigh up to 6 tons, if such estimations are reliable.

I know this is probably very simplistic, but if we wanted our chickenosaurus to grow to the size of a low-estimate Tyrannosaurus, could we do that by adding growth hormone regulating genes from the African bush elephant to the chickenosaurus genome?
