When scientists replace a gene (DNA) from one species with the same gene (DNA) from a different species, the same amino acids will be produced. This happens because all organisms have nucleic acids, so they all produce amino acids
all organisms have DNA, so they produce the same biological molecules
all organisms carry out transcription the same way, so translation produces the same amino acids
all organisms share a common ancestor, so their genetic code is universal

Despite the differences in mature plant cells, all of them are derived from meristem cells. the three major types of tissue systems develop from the meristem. meristems develop cells in all but which tissue?
