What is the error in above diagram?

Arrows are wrongly depicted

Polarity is incorrect

Both arrows and polarity are incorrect

None of the above

(AIIMS-2009)

Solution

The figure below is the replicating fork of $DNA$. The $DNA$ replication takes place in $5'$ to $3'$ direction always. On the leading strand $DNA$ replication is continuous while on lagging strand $DNA$ replication is discontinuous. The polarity of lagging strand is incorrect in the given figure. The correct figure should be

Both the strands are antiparallel. In one strand carbon of sugar are in $3' -5'$ direction and in other the carbon of sugar are in $5' -3'$ direction.
