Re: what is the best way that I can be a genetic engenier ??

Just get your first university/college degree in biochemistry or molecular biology, or 
even biology. (ie. a B.Sc.).

Then I recommend going into graduate level programs, again at university. You can 
get M.Sc or a Ph.D.  If you want to be the person in charge of a lab of your own, 
guiding the research, getting the funding.. then you want to train as a Ph.D.  Your 
Ph.D. can be in biochemistry, or molecular biology, or molecular and cell biology, 
or genetics, or human genetics ...etc.  Just make sure you do graduate level training 
in a lab that does molecular biology.. ie.  research that uses DNA.  In north america, 
students in graduate science programs usually get a stipend or salary, so you do 
not have to go into more debt to get your graduate education.

If you want to be a lab technician, working under a PhD boss, then you can get that 
kind of work with only a B.Sc. 

To follow  what is interesting in molecular biology, when you are in university.. read 
journals like nature, sceince, nature genetics, cell, etc. They have research papers 
but also have good review articles that teach you a large subject area.

Good luck.
