In genetic engineering, why are genes usually transferred to an organism at an early stage of its development?
So that the organism will not pass the new gene on to its offspring
So that the organism develops with the wanted characteristic in it
So that the gene can be taken out again if it is no longer wanted
So that the cells of the organism can divide by meiosis more often
