is there is any feild in biotechnology in Korean or they both are different?
There are no specific field such as biotechnology in Korean. Biotechnology is a science subject while Korean in a language. It depends on the place from where you are pursuing your course. If you do it from colleges in South or North Korea then you will get the biotechnology course explained to you in Korean. Else you can learn biotechnology and an additional language course in Korean (Hangul).
