Read the following four statements (A-D) about certain mistakes in two of them: The first transgenic buffalo Rosie produced milk which was human alpha-lactalbumin enriched. Restriction enzymes are used in isolation of DNA from other macro-molecules Downstream processing is one of the steps of R-DNA technology. Disarmed pathogen vectors are also used in transfer of R-DNA into the host.
