Which type of DNA replication occurs in a eukaryotic cell?
semiconservative DNA replication
These daughter copies each contain one strand from the parental duplex DNA and one nascent antiparallel strand. This mechanism is conserved from prokaryotes to eukaryotes and is known as semiconservative DNA replication.
What is the origin of replication in eukaryotes?
The origin of replication successively binds the origin recognition complex (ORC) and the Cdc6 protein. Together with Cdt1, these then recruit two MCM helicase complexes. This forms the pre-replicative complex (pre-RC). The origin recognition complex recognizes the origins of eukaryotic chromosomes.
What element of replication is used in both prokaryotes and eukaryotes?
coli DNA replication. Instead, it is now clear that both prokaryotic and eukaryotic cells contain several different DNA polymerases that play distinct roles in the replication and repair of DNA. The multiplicity of DNA polymerases was first revealed by the isolation of a mutant strain of E.
What are the characteristics of eukaryotic DNA replication?
Features of Eukaryotic DNA Replication DNA replication uses a semi-conservative method that results in a double-stranded DNA with one parental strand and a new daughter strand. It occurs only in the S phase and at many chromosomal origins. Takes place in the cell nucleus. Synthesis occurs only in the 5′to 3′direction.
How does eukaryotic DNA replication work?
The mechanism of eukaryotic DNA replication is similar to that of prokaryotic DNA replication. However, eukaryotic DNA replication requires special consideration due to differences in DNA sizes, unique linear DNA end structures called telomeres, and distinctive DNA packaging that involves complexes with histones.
How are eukaryotic chromosomes replicated?
As in prokaryotes, the linear chromosomes of eukaryotes replicate by strand separation and complementary base pairing of free deoxyribonucleotides with those on each parent DNA strand. As with prokaryotes, DNA replication in eukaryotic cells is bidirectional.
How is DNA replication different in prokaryotes and eukaryotes?
Eukaryotic DNA replication requires multiple replication forks, while prokaryotic replication uses a single origin to rapidly replicate the entire genome. DNA replication always occurs in the nucleus. Eukaryotic DNA replication involves more polymerases than prokaryotic replication.
What is difference between DNA replication in prokaryotic and eukaryotic?
The main difference between prokaryotic and eukaryotic DNA replication is that prokaryotic DNA replication occurs through a single origin of replication whereas eukaryotic DNA replication occurs through multiple replication origins.
How does DNA replication differ between prokaryotes and eukaryotes?
In prokaryotic cells, there is only one point of origin, replication occurs in two opposing directions at the same time, and takes place in the cell cytoplasm. Eukaryotic cells on the other hand, have multiple points of origin, and use unidirectional replication within the nucleus of the cell.
How does DNA replication differ between eukaryotes and prokaryotes quizlet?
How does DNA replication differ in prokaryotic cells and eukaryotic cells? In most prokaryotic cells, replication starts from a single point, and it continues in two directions until the whole chromosome is copied. In eukaryotic cells, replication may begin in hundreds of places on the DNA molecule.
What features are unique to eukaryotic DNA replication?
However, eukaryotic DNA replication requires special consideration due to differences in DNA sizes, unique linear DNA end structures called telomeres, and distinctive DNA packaging that involves complexes with histones.
What is used in DNA replication?
One of the key molecules in DNA replication is the enzyme DNA polymerase. DNA polymerases are responsible for synthesizing DNA: they add nucleotides one by one to the growing DNA chain, incorporating only those that are complementary to the template.
What does each eukaryotic chromosome contain?
Each eukaryotic chromosome is composed of DNA coiled and condensed around nuclear proteins called histones. Humans inherit one set of chromosomes from their mother and a second set from their father.
What is a major difference between eukaryotic DNA replication and prokaryotic DNA replication quizlet?
What is a major difference between eukaryotic DNA replication and prokaryotic DNA replication? Prokaryotic chromosomes have a single origin of replication, while eukaryotic chromosomes have multiple origins of replication. In E. coli, which enzyme catalyzes the elongation of a new DNA strand in the 5′ → 3′ direction?
How does DNA replication compare between prokaryotes and eukaryotes quizlet?

What are the differences in DNA replication between prokaryotes and eukaryotes?
How DNA replication in eukaryotes is different from prokaryotes?
Which of the following components is required for DNA replication?
DNA replication requires other enzymes in addition to DNA polymerase, including DNA primase, DNA helicase, DNA ligase, and topoisomerase.
