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.
What else can I help you with?
Does DNA replication take place in the same direction along both strands of the DNA?
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.
What characteristic of DNA allows two connected DNA polymerases to synthesize both 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.
Is The lagging strand the strands of parental DNA?
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
Compare the leading and lagging strands during replication?
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.
Which of the following statements best explains why the leading and lagging strands are synthesized using two different mechanisms?
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.
Is RNA polymerase used in both leading and lagging strands of DNA replication?
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.
Does DNA replication take place in the same direction along both strands of the DNA?
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.

This process of replication is slower and requires additional steps compared to the leading strand.
Does dna ligase help assemble the leading strand?
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.
What was the contribution of reiji and tuneko okazaki and colleagues with regard to these replication models?
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.
What is birectional replication in DNA?
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').
Which of the following statements best explains why the leading and lagging strands are synthesized using two different mechanisms?
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.
What is the definition of a lagging 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.
Why are leading and lagging strand primers removed instead of being joined with Okazaki fragments during DNA replication?
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.
Are the leading strand and lagging strand of DNA replication copied in the same direction?
No, both will be synthesized in opposite directions
