The two strands of DNA in animal cells are arranged backwards to each other - the start of one is paired with the ending of the other. However, the enzyme that replicates DNA (DNA polymerase) can only work from start to finish. On one strand, DNA polymerase can work front to back in a continuous chain - the strand that allows this is called the leading strand because it "leads" in completion status. On the other strand, the DNA polymerase has to work backwards in pieces and then put the pieces back together into a single chain - the strand that causes this is called the lagging strand because it "lags behind" the other in completion status.
What else can I help you with?
Which strand (leading or lagging) will have the okazaki fragments?
The lagging strand will have the Okazaki fragments. These short fragments are created as the DNA replication machinery synthesizes the new DNA strand discontinuously in the 5'-3' direction away from the replication fork.
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.
Which DNA polymerase is responsible for removing primers and replacing them with DNA on the lagging strand during DNA replication?
The DNA polymerase responsible for removing primers and replacing them with DNA on the lagging strand during DNA replication is called DNA polymerase I.
What are the fragments making up the noncontinuous strand called?
The fragments making up the noncontinuous strand in DNA replication are called Okazaki fragments. These are short DNA fragments that are synthesized discontinuously on the lagging strand during DNA replication.
How does DNA ligase function in the replication of the lagging strand?
DNA ligase functions in the replication of the lagging strand by joining together the Okazaki fragments, which are short segments of newly synthesized DNA. This enzyme helps to seal the gaps between the fragments, creating a continuous strand of DNA.

The fragments making up the noncontinuous strand in DNA replication are called Okazaki fragments. These are short DNA fragments that are synthesized discontinuously on the lagging strand during DNA replication.
Where does ssb protein bind on lagging strand or on leading strand?
ssb protein bind to the lagging strand as leading strand is invovled in dna replication and lagging strand is invovled in okazaki fragment formation

DNA ligase functions in the replication of the lagging strand by joining together the Okazaki fragments, which are short segments of newly synthesized DNA. This enzyme helps to seal the gaps between the fragments, creating a continuous strand of DNA.
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
What are the small segments synthesized in the lagging strand of DNA?
Okazaki fragments are the small DNA fragments synthesized on the lagging strand during DNA replication. They are later joined together by DNA ligase to form a continuous strand.
What DNA replication enzyme attaches okazaki fragments as a continuous strand of DNA?
Ligase joins okazaki fragments to each other to form a continuous strand of DNA
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.
Are the leading strand and lagging strand of DNA replication copied in the same direction?
No, both will be synthesized in opposite directions
The enzyme that restores the phosphodiester linkage between adjacent fragments in the lagging strand during DNA replication is?
DNA ligase. It plays a crucial role in DNA replication by creating a phosphodiester bond between the Okazaki fragments in the lagging strand to complete the DNA synthesis process.
