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.
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
How many stands make up DNA double helix?
The DNA double helix contains two coiled biopolymer strands. The double helix was discovered by James Watson and Francis Crick.
Why does Dna have both leading and lagging Strands?
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.
At each replication fork one new strand of DNA is made of many small pieces. what is the strand of DNA called?
When the two parent strands of DNA are separated to begin replication, one strand is oriented in the 5' to 3' direction while the other strand is oriented in the 3' to 5' direction. DNA replication, however, is inflexible: the enzyme that carries out the replication, DNA polymerase, only functions in the 5' to 3' direction. This characteristic of DNA polymerase means that the daughter strands synthesize through different methods, one adding nucleotides one by one in the direction of the replication fork, the other able to add nucleotides only in chunks. The first strand, which replicates nucleotides one by one is called the leading strand; the other strand, which replicates in chunks, is called the lagging strand. The lagging strand replicates in small segments, called Okazaki fragments. These fragments are stretches of 100 to 200 nucleotides in humans (1000 to 2000 in bacteria).
Is RNA polymerase used in both leading and lagging strands of DNA replication?
the leading strand is synthesized in the same direction as the movement of the replication fork, and the lagging strand is synthesized in the opposite direction
How many strands are replicated in DNA replication?
Two - the leading strand and the lagging strand.

In the replication of DNA what is the name of the enzyme which joins the lagging strands together?
DNA ligase

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').
What happens when a helicase doesn't work?
Replication would be hard pressed to take place. Helicase is the enzyme that splits the double helix and unwinds this helix so that DNA polymerase can do it's job of running the leading and lagging strands of DNA in the replication process.

What are three types of strands in replication?

The continually elongating strand of new dna at one side of a replication fork during dna replication is known as?
The strand of DNA that is being continually created is known as the leading strand. The strand that is being created in sections/loops is known as the lagging strand. The reason that these two strands are created differently is because the two strands of DNA run in different directions (they are anti-parallel). This means that because new nucleotides can only be added in a 5'-3' direction, the two strands cannot be created in the same method.
