Bacteria are excellent candidates for genetic engineering because?

These prokaryotes, can be utilized for almost mass producing compatible human proteins, by placing a nucleotide sequence onto a plasmid, and placing it into the bacteria, letting the bacteria undergo reproduction, especially if the plasmid is integrated with the bacterial chromosome and undergoes transcription, more and more of the protein product can be made

Then can be extracted after lysing the cell, and using it for medical purposes for instance.

The process that makes it possible for all of the body's major organs to be formed by the tenth week of gestation is known as differentiation. This process of differentiation starts around week 5 of the pregnancy where the embryo begins to develop most of its internal organs as well as external body structures which includes the biological sex of the child. This process will continue until week 10 of the pregnancy and the only organs or parts of the body that are not developed at this point are the brain and spinal cord.
