Re: where should I start from, for a career in genetic engineering?

There are many areas of speciality in what you're calling genetic
engineering and many levels at which you can develop a career.  Given you
already have a business degree, you could try applying to biotech
companies.  Many hire for the business side but do offer inhouse training
to get employees up to speed.  You could also try community colleges, some
have training programs for people who want to work in the industry.  There
are a number of very good masters level programs, masters of public health,
masters of human genetics (genetic counselling). Most universities and
colleges offer part time classes, you can find out if you can audit the
classes.  Most science centers also have outreach educational programs --
these are a lot less formal.  If it's getting informed, there are general
texts, biographies, TV shows etc.  We have produced a number of online
educational resources -- Internet sites:  DNA from the Beginning
(www.dnaftb.org), DNA Interactive (www.dnai.org).  These would certainly
give you a good overview and introduce you to certain concepts.  Good luck.
