The lagging strand is called the lagging strand because, unlike the leading strand, DNA polymerase can not replicate in a 5' to 3' uninterrupted flow on this strand. Remember, DNA has two strands that run ANTIPARALLEL, one to the other; in other words they run in opposite directions.
No, DNA replication does not take place in the same direction along both strands of the DNA. It occurs in opposite directions on the two strands, known as the leading and lagging strands.
The antiparallel nature of DNA strands allows for simultaneous synthesis of leading and lagging strands. One polymerase moves in the 5' to 3' direction along the leading strand, while a second polymerase moves in the opposite direction on the lagging strand to create short Okazaki fragments.
which statement about dna replication is correct? A. the leading strand is one of the strands of parnetal Dna b. the leading strand is built continuously, and the lagging strand is built in pieces c. the lagging strand is one of the strands of parental Dna d. Dna ligase helps assemble the leading strand e. the lagging strand is built continuously
The leading strand is synthesized continuously in the 5' to 3' direction, making replication faster and more efficient. The lagging strand is synthesized discontinuously in short fragments called Okazaki fragments, which are later joined together by DNA ligase. This process of replication is slower and requires additional steps compared to the leading strand.
The leading strand is created continuously, but the lagging strand is created as small fragments, known as Okazaki fragments. These fragments are later joined together to form one complete strand.
No, RNA polymerase is not used in both leading and lagging strands of DNA replication. RNA polymerase is responsible for transcribing DNA into RNA during gene expression, while DNA polymerase is responsible for synthesizing new DNA strands during replication. DNA polymerase is used on both the leading and lagging strands during DNA replication.

No, DNA ligase does not help assemble the leading strand. DNA ligase is primarily involved in the final stages of DNA replication, where it seals the nicks in the phosphodiester backbone between Okazaki fragments on the lagging strand. DNA polymerase is responsible for assembling both the leading and lagging strands during DNA replication.
Reiji and Tsuneko Okazaki, along with colleagues, discovered short DNA fragments called Okazaki fragments that are synthesized discontinuously during DNA replication on the lagging strand. Their work helped to elucidate the process of DNA replication and how it occurs on both the leading and lagging strands, leading to the development of the Okazaki fragment model for DNA replication.
A DNA molecule has two complementary strands, the top (leading) one is 5' to 3' and the bottom (lagging) one is 3' to 5'. The 5' carbon has a phosphate group linked to it and the 3' carbon has a hydroxyl group. During replication, both strands get replicated however DNA strands due to their molecular structure can only be replicated from 5' to 3' so the lagging strand is replicated in 5' to 3' pieces called Okazaki fragments. However, even with this, replication still happens in both strands, even if in the same direction (5' to 3').
The leading strand is created continuously, but the lagging strand is created as small fragments, known as Okazaki fragments. These fragments are later joined together to form one complete strand.
A lagging strand is one of two strands of DNA found at the replication fork, or junction, in the double helix; the other strand is called the leading strand. A lagging strand requires a slight delay before undergoing replication, and it must undergo replication discontinuously in small fragments.
Leading and lagging strand primers are removed during DNA replication because they are only needed temporarily to initiate the synthesis of new DNA strands. Once the Okazaki fragments are synthesized, the primers are no longer necessary and must be removed to allow for the joining of the fragments into a continuous DNA strand.
No, both will be synthesized in opposite directions
