1. In eukaryotic cells replication forks make several start sites along the DNA strand which forms replication "bubbles" which get larger the more DNA is copied, and stop when DNA replication is complete.
In prokaryotic cell's DNA is formed in a loop, two replication forks start along one part of the loop (origin replication) and the replication forks copy DNA in opposite directions until they meet at the other side of the loop, making an exact copy of DNA.
What else can I help you with?
Why does replication in prokaryotes differs from replication in eukaryotes?
Replication in prokaryotes differs from replication in eukaryotes for prokaryotic chromosomes have a single origin of replication, whereas eukaryotic chromosomes have many. Eukaryotes and prokaryotes for replication double stranded DNA, four kinds of dNTPS, primers, and origins.
In prokaryotes where does DNA replication occur in the cell?
In prokaryotes, DNA replication occurs in the cytoplasm. The replication process begins at the origin of replication on the DNA molecule and proceeds bidirectionally. Multiple replication fork structures are formed to speed up the replication process.
What structure is present in eukaryotes but not in prokaryotes?
dna
Is DNA contained within a nucleus for both prokaryotes and eukaryotes?
No, in prokaryotes like bacteria, the DNA is not contained within a nucleus. Instead, it is found in a region called the nucleoid within the cell. Eukaryotes, on the other hand, have their DNA located within a membrane-bound nucleus.
What are enzymes that have a proofreading role in DNA replication?
DNA polymerases, such as DNA polymerase III in prokaryotes and DNA polymerase delta in eukaryotes, have proofreading activities during DNA replication. These enzymes possess exonuclease activity, allowing them to detect and correct errors in newly synthesized DNA strands by removing misincorporated nucleotides. This proofreading function helps maintain the fidelity of DNA replication.
Why does replication in prokaryotes differs from replication in eukaryotes?
Replication in prokaryotes differs from replication in eukaryotes for prokaryotic chromosomes have a single origin of replication, whereas eukaryotic chromosomes have many. Eukaryotes and prokaryotes for replication double stranded DNA, four kinds of dNTPS, primers, and origins.
How is the DNA in prokaryotes different from from the DNA in a eukaryotes?
dna in eukaryotes is located in the nucleus
What sets of materials are required by both eukaryotes and prokaryotes for replication?
Both eukaryotes and prokaryotes require nucleotides (A, T/U, C, G) for DNA replication, DNA polymerase enzymes for synthesizing new DNA strands, and primers to initiate the replication process. Other materials like ATP for energy and various cofactors and proteins are also necessary for efficient DNA replication.
Who has dna domains- prokaryotes or eukaryotes?
I think prokaryotes
In prokaryotes where does DNA replication occur in the cell?
In prokaryotes, DNA replication occurs in the cytoplasm. The replication process begins at the origin of replication on the DNA molecule and proceeds bidirectionally. Multiple replication fork structures are formed to speed up the replication process.
There are differences and similarities between prokaryotes and eukaryotes the similarities are?
Similarities between prokaryotes and eukaryotes include both having DNA as genetic material, ribosomes for protein synthesis, and cell membranes to contain their contents. Additionally, they both carry out essential cellular processes such as metabolism and replication.
What structure is present in eukaryotes but not in prokaryotes?
dna
How is the DNA prokaryote different from the DNA in a eukaroyte?
In Prokaryotes like bacteria DNA is in the form of clusters of chromosomes and in eukaryotes DNA is concentrated in the nucleus as they have it .
How is the DNA in a prokaryotes different from the DNA in a eukaryote?

How is the DNA in a prokaryotes different from the DNA in the eukaryote.?

How many DNA fragments result from 2 site digestion?
Three in eukaryotes and two in prokaryotes. Think of it this way: suppose you had a string and you cut it in two different places. How many resulting strings would you have? The difference in eukaryotes and prokaryotes is due to the shape of DNA - in eukaryotes, DNA is linear; in prokaryotes, DNA is circular.
How are eukaryotes and prokaryotes the different?
Prokaryotic cells do not have a nucleus and eukaryotic cells do. The main difference to remember is that everything in a eukaryotic cell is much larger and more complex than what would be fouind in a prokaryotic cell. Bacteria is made of prokaryotic cells. Plants and animals are made of eukaryotic cells. In addition to not having a nucleus (the main difference), prokaryotes also have circular DNA while eukaryotes have linear DNA. As such, prokaryotes do not have okazaki fragments formed during DNA replication. Eukaryote genes have introns and exons while prokaryotes do not, and eukaryotes have more "junk" DNA in general.
