Amongst the following four statements (A-D), some are wrong.
Unarmed pathogen vectors are also used in the transfer of DNA into the host.
Restriction enzymes are used in isolation of DNA from other macro-molecules.
Downstream processing is one of the steps of biotechnology.
The first transgenic sheep, Rosie, produced enriched milk with human alpha-lactalbumin.
Which of these statements are with mistakes?
Options:
Answer:
Solution:
First transgenic cow was named Rosie that produced milk with human alpha-lactalbumin. It wasper litre. Restriction enzymes are used to cut DNA at specific sequences. Downstream processing is an important step in biotechnology. It includes collection and purification of materials. The pathogens to be used in transfer of DNA should be unarmed or disarmed which means it should not be able to cause any disease.
