Yes, it is true that the elongation of the lagging strand during DNA replication does not require a template strand in the same way that the leading strand does. While the lagging strand is synthesized in short fragments called Okazaki fragments, each fragment is initiated by an RNA primer, which provides the necessary 3' hydroxyl group for DNA polymerase to extend the strand. However, the synthesis of these fragments is still directed by the template strand to ensure accurate base pairing.
What else can I help you with?
What is primer in pcr?
A primer (oligonucleotide of a specific sequence) is required for Taq polymerase to extend the template strand by adding complementary nucleotides. The function of the primer is to anneal to the template strand at a very specific site and facilitate the initiation of strand elongation mediated by Taqploymerase.
What strand needs multiple primers?
The strand that needs multiple primers is the lagging strand during DNA replication. This strand is synthesized discontinuously in short segments called Okazaki fragments, each requiring a separate RNA primer. These primers are essential for initiating DNA synthesis at various points along the lagging strand template. In contrast, the leading strand is synthesized continuously from a single primer.
What letter indicates the strand that will require the function of DNA ligase?
The letter that indicates the strand requiring the function of DNA ligase is "Lagging strand." During DNA replication, the lagging strand is synthesized in short fragments called Okazaki fragments, which need to be joined together by DNA ligase to create a continuous strand.
What is required to required to replicate the lagging strand of DNA?
To replicate the lagging strand of DNA, several key components are necessary: DNA polymerase, which synthesizes the new DNA strand; RNA primase, which lays down short RNA primers to provide a starting point for synthesis; and DNA helicase, which unwinds the double helix to allow access to the template strand. The lagging strand is synthesized in short segments called Okazaki fragments, which are later joined together by DNA ligase. Additionally, the presence of nucleotide triphosphates (dNTPs) is essential for the formation of the new DNA strand.
How do you measure strand elongation?
Strand elongation is typically measured by comparing the length of the strand before and after stretching or extending. This can be done using instruments like a ruler, calipers, or specialized equipment for accurate measurements. The elongation is usually calculated as a percentage increase in length from the original strand dimension.
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

The function of the primer is to anneal to the template strand at a very specific site and facilitate the initiation of strand elongation mediated by Taqploymerase.
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
In which direction does replication occur 3 to 5 or 5 to 3?
Replication occurs in the 5' to 3' direction. The new DNA strand is synthesized in the 5' to 3' direction, while the parental template strand acts as the template for this synthesis. This directionality allows for continuous synthesis on one strand (leading strand) and discontinuous synthesis on the other strand (lagging strand).
What strand needs multiple primers?
The strand that needs multiple primers is the lagging strand during DNA replication. This strand is synthesized discontinuously in short segments called Okazaki fragments, each requiring a separate RNA primer. These primers are essential for initiating DNA synthesis at various points along the lagging strand template. In contrast, the leading strand is synthesized continuously from a single primer.

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.
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.
There is a y shaped replication fork on each side of each replication bubble what are the sides of the replication fork called?
One is known as the Leading strand, and the other is known as the Lagging strand.
What is required to required to replicate the lagging strand of DNA?
