Detailed explanation-1: -The strand that runs in the 5’ to 3’ direction in the replication fork is referred to as the leading strand. The strand is replicated discontinuously. The strand is replicated continuously. Short stretches called okazaki fragments are formed during replication.
Detailed explanation-2: -The leading strand is a single DNA strand that, during DNA replication, is replicated in the 3’ – 5’ direction (same direction as the replication fork). DNA is added to the leading strand continuously, one complementary base at a time.
Detailed explanation-3: -During DNA replication, one new strand (the leading strand) is made as a continuous piece. The other (the lagging strand) is made in small pieces.
Detailed explanation-4: -One strand is synthesized continuously in the direction of the replication fork; this is called the leading strand.
Detailed explanation-5: -The parent strand that runs in the 3’ to 5’ direction can be easily read by DNA polymerase and as a result, this newly synthesized strand of DNA is called the leading strand. The leading strand is synthesized continuously in the forward direction (same direction as the movement of the replication fork).
