Answer:
1) Altering the DNA of organisms is considered controversial because we do not know what circumstances might occur if the DNA which is being altered turns out to have adverse effect on the organism. There are also concerns that altering the genome and producing organisms with better traits might eradicate the particular wild type organisms on the whole.
2)Yes, there should definitely be a guideline as to who can you the recombinant DNA technology and up to what limits. If guidelines are not set up then it can lead to serious devastating results. We might end up making manipulations which can be very harmful for life. Hence, recombinant DNA technology should be used with much care and under strict guidelines.
3) The techniques in recombinant DNA technology has enable us to make precise changes in the DNA at a higher frequency but certain guidelines shall be set up to control the devastating results which might occur. The concern related to life shall be the first and foremost concern while practicing such techniques.
