What are two differences between DNA replication in prokaryotes vs eukaryotes?
What are two differences between DNA replication in prokaryotes vs eukaryotes?
Both prokaryotic and eukaryotic DNA undergo replication by the enzyme DNA polymerase. The main difference between prokaryotic and eukaryotic DNA is that prokaryotic DNA is found in the cytoplasm whereas eukaryotic DNA is packed into the nucleus of the cell.
What is one major difference in prokaryotic replication vs eukaryotic replication?
Prokaryotic Replication vs Eukaryotic Replication
| Prokaryotic Replication | Eukaryotic Replication |
|---|---|
| It is a continuous process. | This process occurs in the S-phase of cell cycle. |
| Circular, double-stranded DNA | Linear, double-stranded DNA with end |
| The DNA replicates in the cytoplasm | The DNA replicates in the nucleus |
How does replication occur in prokaryotes?
DNA Replication in Prokaryotes: A replication fork is formed when helicase separates the DNA strands at the origin of replication. On the leading strand, DNA is synthesized continuously, whereas on the lagging strand, DNA is synthesized in short stretches called Okazaki fragments.
Why DNA is packaged?
DNA is tightly packed up to fit in the nucleus of every cell. As shown in the animation, a DNA molecule wraps around histone proteins to form tight loops called nucleosomes. Condensing DNA into chromosomes prevents DNA tangling and damage during cell division.
What is the difference between DNA and chromosome?
DNA is the smallest part that, together with proteins, forms a chromosome. A chromosome is therefore, nothing but a chain of DNA that has been made compact enough to fit into a cell. 2. A chromosome is a subpart of a person’s genes, while DNA is a part of the chromosome.
What is the function of each chromosome?
Chromosomes are located inside of the nucleus of cells. Each chromosome is one long single molecule of DNA. This DNA contains important genetic information. Chromosomes have a unique structure, which helps to keep the DNA tightly wrapped around the proteins called histones.
Why is everyone’s DNA different?
Why is every human genome different? Every human genome is different because of mutations—”mistakes” that occur occasionally in a DNA sequence. When a cell divides in two, it makes a copy of its genome, then parcels out one copy to each of the two new cells. These genome variations are uniquely yours.
Are 11th cousins blood related?
No, not at the 11th cousin degree is everyone related. A great many people are 11th cousin or closer to you, but not all. Many of these, if not most of them, are related to you in more than one way. Those are people who have a common ancestor with you where the common ancestor was living about 500 years ago.
How many descendants will I have in 100 years?
It is not uncommon for some to find five generations in the past 100 years, although four will be an average for this example. Conversely, your future generations will wait longer to have children; therefore, expect only three generations in the next 100 years.
