A scientist is using an ampicillin-sensiitive strain of bacteria that cannot use lactose because it has a nonfunctional gene in the lac operon. She has to plasmids. One contains a functional copy of the affected gene of the lac operon, and the other contains the gene for ampicillin resistance. Using restriction enzymes and DNA ligase, she forms a recombinant plasmid containing both genes. She then adds a high concentration of the plasmid to a tube off the bacteria in a medium for bacterial growth that contains glucose as thee only energy source. This tube (+) and a control tube (-) with similar bacteria but no plasmid are both incubated under the appropriate conditions for growth and plasmid uptake. The scientist then spreads a sample of each bacterial culture (+ and - ) on each of the three types of plates indicated below.

With frozen embryos,invitrofertilization techniques perfected in 2007,genetic code pre dertermined by picking the sex,hair and eye color,and possibly cloning off of people who lived thousands of years ago. Is it possible that some mad scientist are out there creating creatures such as half horse,half man,such as in Greek Mythology for war time purposes,or perhaps half gorilla,half man,for scientific research.
Crazy scientific mad research,could have been done during WWII,so why not today in this crazy society we live in now . Do you think it is going on ?

If I complete 3 years of experience working as a clinical lab tech, take chemistry/biochem/biology free online courses offered by major universities such as MIT's at http://ocw.mit.edu/OcwWeb/Global/all-courses.htm#Biology , If I complete an associates degree in Medical lab, and if I have a BS degree in computer engineering.

Any comments will be greatly appreciated
