9.Biotechnology Principals and Process
medium
The key tools required for the recombinant $DNA$ technology are
$I.$ Enzymes
$II$. RNA primer
$III.$ DNA probe
$IV.$ Vectors
$V.$ host organisms
Select the correct option
A
$I, II \;and \;III$
B
$I, IV\; and$ $\mathrm{V}$
C
$I, II, III\; and$ $\mathrm{V}$
D
$I, II, III, IV \;and\; V$
Solution
$3$ types of 'biological tool' are used in the formation of recombinant $DNA$. $(ii)$ Cloning vectors (vehicle vectors). $(iii)$ Complementary host (for transformation with recombinant $DNA$). Probes are used for detection of mutated/defect /samping of $DNA$. Primers are tools of $PCR$
