The first discovery of homeotic genes was in Drosophila fruit flies. Homeotic genes control differentiation of tissues and organs in embryos. Altering homeotic genes can result in impaired limb and tissue development and, in some cases, the death of offspring. Which of the following is true of homeotic genes?
They direct the process of cell division within the embryo
They direct proteins to bind to RNA, increasing gene expression at certain times
They were prominent in prokaryotes because they are very conserved when passed down to eukaryotes
They promote cell
differentiation of liver cells
