(D) Statement $1$ is incorrect because Rosie was the first transgenic cow,not a buffalo.Statement $2$ is incorrect because restriction enzymes are used to cut $DNA$ at specific sites,not for the isolation of $DNA$ from other macromolecules (which is done by chemical treatment and centrifugation).Statement $3$ is correct as downstream processing is a vital step in $R-DNA$ technology.Statement $4$ is correct as disarmed pathogen vectors are commonly used to transfer $R-DNA$ into host cells.Therefore,statements $1$ and $2$ contain mistakes.

Read the following four statements $(1-4)$ and identify the two statements that contain mistakes:
$1.$ The first transgenic buffalo,Rosie,produced milk which was human alpha-lactalbumin enriched.
$2.$ Restriction enzymes are used in the isolation of $DNA$ from other macromolecules.
$3.$ Downstream processing is one of the steps of $R-DNA$ technology.
$4.$ Disarmed pathogen vectors are also used in the transfer of $R-DNA$ into the host.
Which are the two statements having mistakes?
