Hello,

If you want to be an space research biologist then it's very good career dear. Every space like ISRO, NASA have the space biologist. They want cell and molecular biologist for checking the stresses of the space light environment affect living systems. So if you go for this zone then after 12th you have to study in BSC in molecular biology or BSC in microbiology in this department. Then you will get more chances to join the space research centre.

All the best.
