Using the Genome Sequencing Data from Each of the Kingdoms

Using the genome sequencing data from each of the kingdoms, it is currently possible to

A) to genetic differences between species very directly, examining DNA changes and identifying unknown genes.
B) to build, from scratch, complex organisms with trans-kingdom genomes using newly-sequenced genes.
C) to sequence genes and build, from scratch, simple organisms with trans-kingdom genomes.
D) to design humans with a variety of inter-kingdom abilities built into their DNA.
