The strand of DNA made of many small pieces at each replication fork is called the lagging strand. It is synthesized discontinuously in the form of short fragments known as Okazaki fragments. These fragments are later joined together by DNA ligase to generate a continuous strand.

Explain the function of replication?
DNA replication requires the opening of the 'zipped up' DNA strand. This is so a 'new' strand of DNA can be inserted and have a template strand to 'read' off. DNA polymerase analyses the bases on the template strand and adds each complementary base to synthesise the 'new' strand. In order for DNA polymerase to be able to do this the DNA has to be opened up by helicase to reveal the bases of the template strand. The unzipping of the DNA by helicase forms the replication fork. Thus the function of the replication fork is to reveal template strands for DNA replication to actually occur.
What base sequence would be produced through DNA replication?
DNA replication is a semi-conservative process. The DNA is split into two strands. Nucleotides are then attached to each strand by complementary base pairing, where A attaches to T and G attaches to C. The newly formed strand is hence identical to the old strand and the base sequence of DNA can hence be conserved during replication.
Can DNA be described as conservation?
DNA replication is semi-conservative. This means that each new DNA molecule has one original strand of DNA and one new strand of DNA.
During DNA replication each strand of DNA is used as a template to produce a complementary strand of DNA. This process is shown below. Which base will attach to location 1?
Guanine
A single DNA acts acts as a template for strand?
the progeny of each cellular replication gets the same genetic information
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.
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).
At the end of replication each new DNA molecule is composed of?
After DNA replication, each new molecule has one strand of the original DNA molecule and the other strand is composed of new nucleic acids. This is due to the semi-conservative replication of DNA.
What does semi conservation mean in terms of DNA replication?
DNA Replication is semi-conservative because each DNA molecule is composed of 1 old strand and 1 new strand
What happens after replication?
each new DNA double helix consists of one old strand and one new strand
What is the name of the DNA replication process that produces two identical DNA molecules each consisting of one parent strand and one daughter strand?
I'm not an expert on this subject but as I've learned, DNA is split into two replication forks where the complimentary base pairs and other backbones are added on, so ideally it would be 50% of the original strand in each daughter strand.
Why is DNA replication caled semiconverative?
Because when the two strands of the double helix are unwound for replication each strand acts as a template to replicate a new strand onto. So, you get four strands, two pair. One of that pair is a new strand and one of the pair is the old strand that was the template strand.
During dna replication each double helix produced consists of?
one parent strand and one new strand of DNA.
What is an end replication problem?
The two strands of a DNA molecule are antiparallel to one another (the backbone of one strand runs from 5'-3' while the complimentary strand runs 3'-5'). Unfortunately, DNA polymerase, the enzyme responsible for replicating DNA, can only make DNA in a 5'-3' direction (and read DNA in the 3'-5' direction). Also, it needs a "primer" to give it a place to bind and start replication. So this creates a problem when synthesizing the 3'-5' stand because your enzyme will only synthesize 5'-3'. During replication this is solved by synthesizing small pieces of DNA ahead of the replication fork on the 5'-3' mother strand. Thus we have one daughter strand which is synthesized as a continuous piece of DNA (called the leading strand) and one daughter strand which is synthesized in small, discontinuous pieces (called the lagging strand). However, at the extreme end of the DNA, we run into another problem. The leading stand can be made to the very end, but the lagging strand cannot because you need the RNA primer upstream to begin each piece of the lagging strand DNA but at the end of the DNA there is nothing for this piece to attach to. Thus, the last section of the lagging strand cannot be synthesized and after several rounds of DNA replication, the DNA molecule gets smaller and smaller. This is "the end of replication problem" and it is solved by putting a DNA cap on the ends of DNA called a telomere which does not code for any protein, thus when this information is lost it does not have severe consequences for the cell.
IMPORTANT After DNA replication does half of the old strand leave with half of the new strand?
The process of DNA replication is described as being semi-conservative. The complementary DNA strands are pulled apart, new matching nucleotides are connected to each separate strand, and the result is two new strands that each contain exactly one-half of the original DNA strand.
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
In the semi-conservative hyposistyesis of DNA replication what proportion of a parent DNA strand is contained by each daughter DNA strand?
The replication is semiconservative. Each strand acts as a template for the synthesis of a new DNA molecule by the sequential addition of complementary base pairs, thereby generating a new DNA strand that is the complementary sequence to the parental DNA. Each daughter DNA molecule ends up with one of the original strands and one newly synthesized strand.
