The separation of strs using capillary electrophoresis: evolved from the flat-gel electrophoresis approach. decreases analysis time. is currently the preferred method. all of the above

Option D , All of the above

Explanation:

Capillary electrophoresis (CE) is used to separate STRs in a much effective way as compared to the traditional slab-gel electrophoresis method-  

a)CE method is a speedy process

b)It automates the DNA-typing procedures

Being an emerging technology, CE possesses following advantages –  

a)The critical processes such as injection, separation can be fully automated

b)These process can also be made speedy through appropriate and efficient heat dissipation

c)Waste is reduced  

Hence, option D is correct

really dont know just need some points
