Question

Match the entries in column I with those of column II and choose the correct answer.
$\begin{array}{cc}ColumnI& ColumnII\\ A)Alkalitreatment& M)separationofDNAfragmentsongelslab\\ B)Southernblotting& N)splitDNAfragmentsintosinglestrands\\ C)Electrophoresis& O)DNAtransferredtonitrocellulosesheet\\ D)PCR& P)X-rayphotography\\ E)Autoradiography& Q)producefragmentsofdifferentsizes\\ F)DNAtreatedwithREN& R)DNAamplification\end{array}$

• A. A - N, B- Q, C- P, D- R, E- M, F - O
• B. A - P, B - R, C - M, D -O, E - N, F - Q
• C. A - Q, B - O, C - M, D - R, E - P, F - N
• D. A - N, B - O, C - M, D - R, E - P, F - Q

Answer 1

The correct option is D A - N, B - O, C - M, D - R, E - P, F - Q

Alkali treatment $\to$ split DNA fragments into single strands
Southern blotting $\to$ DNA transferred to nitrocellulose sheet
Electrophoresis $\to$ separation of DNA fragments on gel slab
PCR $\to$ DNA amplification
Autoradiography $\to$ X-ray photography
DNA treated with REN $\to$ produce fragments of different sizes
