The 5? end of the DNA growing strand during DNA replication

(I answered \'d) is the part of the strand that is added first.\', which is wrong... Can anyone tell me the correct answer? If possible explain.)

The 5? end of the DNA growing strand during DNA replication

a)		does not contain a phosphate group on the ribose.
b)		could contain the base uracil.
c)		is the part of the strand that is added last.
d)		is the part of the strand that is added first.
e)		is the end of both strands of DNA in a double helix.

(I answered \'d) is the part of the strand that is added first.\', which is wrong... Can anyone tell me the correct answer? If possible explain.)

The synthesis of DNA takes place only in 5’to 3’end however during replication one strand grows at its 3’end while the other strand grows at its 5’end. On the lagging strand, DNA grows in the 3’to 5’direction using okazaki fragments. Then the 5’end of the DNA growing strand would be the last part on the strand.

Therefore, the correct answer is option (c).
