A) modern vertebrate species all evolved from very different ancestral species,so there is little similarity between their genomes.
B) modern vertebrate species all evolved from the same ancestral species,but they have changes so that their genomes are very different in modern times.
C) ancestral species contained very similar genomes,but modern vertebrate species have significant differences in their genomes.
D) modern vertebrate species evolved from the same ancestors and a large portion of their genome is conserved.
E) neither the ancestral species nor the modern one resemble each other genetically.

Multiple Choice
A) The foreign DNA enters the cell through self-healing holes in the membrane but it could not pass through the cell wall.
B) The cell wall prevents the transgenic cell from growing into a mature plant.
C) The cell wall makes it difficult for the biotechnician to determine if the foreign DNA has been incorporated into the cell's genome.
D) The cell wall prevents the microinjection of foreign DNA into the cell because the needle cannot pass through it.
E) The foreign DNA passes through the plasmodesmata of the plant cell,which is blocked by the cell wall.
