Which daughter strand elongates away from the replication fork?
Which daughter strand elongates away from the replication fork?
The Leading and Lagging Strands The “lagging strand” is synthesized in the direction away from the replication fork and away from the DNA helicase unwinds.
Does the lagging strand grow away from the replication fork?
The other strand, known as the lagging strand, forms away from the replication fork in small fragments. DNA replication occurs both continuously and discontinuously at the same time. Nucleotides can only be added to a new strand of DNA on the 3′ end, so the process has to start with the 5′ end.
What elongates the lagging strand?
Lagging strand DNA elongation proceeds by discontinuous synthesis of short stretches of DNA, known as Okazaki fragments, from RNA primers; these fragments are then joined by DNA ligase.
Which of the following is a reason that a new DNA strand elongates only in the 5 to 3 direction during DNA replication?
why does a new DNA strand elongates only in the 5′ to 3′ direction? DNA polymerase can only add nucleotides to the free 3′ end.
What is the difference between and leading and lagging strand?
The separated DNA strands form a replication fork, where both the DNA strands get replicated forming a lagging and leading strand. The major difference between a lagging and leading strand is that the lagging strand replicates discontinuously forming short fragments, whereas the leading strand replicates continuously.
Which strand is synthesized towards the replication fork?
the leading strand
One strand is synthesized continuously in the direction of the replication fork; this is called the leading strand. The other strand is synthesized in a direction away from the replication fork, in short stretches of DNA known as Okazaki fragments. This strand is known as the lagging strand.
What is the difference between the leading strand and the lagging strand in DNA replication quizlet?
What is the difference between the leading strand and the lagging strand in DNA replication? The leading strand is synthesized in the 3′ → 5′ direction in a discontinuous fashion, while the lagging strand is synthesized in the 5′ → 3′ direction in a continuous fashion.
How does replication of the leading and lagging strands differ?
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. The leading strand is synthesized at twice the rate of the lagging strand.
Which of the following enzymes elongates in DNA replication?
DNA polymerase
DNA polymerase elongates the DNA during replication. RNA polymerase makes RNA from a template strand of DNA.
What is the lagging strand in DNA replication?
The lagging strand is a single DNA strand that, during DNA replication, is replicated in the 5′ – 3′ direction (opposite direction to the replication fork). DNA is added to the lagging strand in discontinuous chunks called ‘okazaki fragments’.
Why does a new DNA strand elongates only in the 5 to 3 direction quizlet?
A new DNA strand elongates only in the 5′ to 3′ direction because? DNA polymerase can only add nucleotides to the free 3′ end.
Why can new nucleotides only be added in a 5 to 3 direction?
DNA polymerase adds nucleotides to the deoxyribose (3′) ended strand in a 5′ to 3′ direction. Lagging strand is synthesised in fragments. Nucleotides cannot be added to the phosphate (5′) end because DNA polymerase can only add DNA nucleotides in a 5′ to 3′ direction.
