DNA in Eukaryote long and linear?
DNA in Eukaryotic cells are linear. DNA in Prokaryotic cells are circular.
Do eukaryotic cells have the same shape?
No. Almost all plant and animal cells are Eukaryotic, and there are a wide variety of shapes, from the long and slender sperm to a rigid cuboid epithelial cell.
What makes it challenging to package genetic material in eukaryotic cells?
Packaging genetic material in eukaryotic cells is challenging because the DNA is wrapped around histone proteins to form chromatin, which must be tightly regulated to allow for processes like transcription and replication. Additionally, eukaryotic cells have a larger genome size compared to prokaryotic cells, requiring more sophisticated mechanisms to organize and compact the DNA. The presence of introns, repetitive sequences, and regulatory elements also add complexity to packaging genetic material in eukaryotic cells.
How is DNA packing in eukaryotic and prokaryotic cells different?
In a prokaryotic cell, there is no nuclear membrane surrounding the chromotin, while in a eukaryotic there is one. in both, the DNA is attached to proteins which create long fibers of chromotin.
Are eukaryotic cells larger than prokaryotic cells?
They generally are due to the fact that they are much more complex than prokaryotic cells, but there are some very small Eukaroytic cells (such as the sperm: 40 microns), that are smaller than some large Prokaryotic cells (the largest found so far is 660 microns long). As a rule of thumb, though, Eukaryotic cells are larger than Prokaryotic cells.
How long the prokaryotes populated Earth before the evolution of eukaryotic cells which are more complex?
Prokaryotes populated Earth for about 1.5 billion years before the evolution of eukaryotic cells, which are more complex. Eukaryotic cells are believed to have evolved around 2 billion years ago through a process called endosymbiosis.
Are plant and animal cells eukaryotic or prokaryotic?
Plant and animal cells are both eukaryotes. However, some animal cells may be prokaryotes, like red blood cells. RBC do not have nucleus. They are considered prokaryotes, so they do not live long.
What are long fibers of DNA and protein called?
Long fibers of DNA and protein are called chromatin. Chromatin is the material that makes up chromosomes in eukaryotic cells and is composed of DNA wrapped around histone proteins.
Did they have cancer in the 1930s?
Yes. They didn't have the same diagnosis tools and treatments but cancer has been around for as long as there have been cells.
What is the difference in a eukaryotic and a prokaryotic cell?
One of the main differences is in what the names mean. Pro- means before. Cary- means nut (nucleus) and -otic means the process of. So Procaryotic means before the process of the nut (nucleus). These cells are rather primitive and where here long before eucaryotic cells. The word eucaryotic means the process of the new nut. The eucaryotic cell has a membrane around the nucleus and the procaryotic cell does not. Bacteria are procaryotic and our cells are eucaryotic.
Is an animal cell a prokaryote or a eukaryote?
A Animal Cell is both a Eukaryotic and Prokaryotic Cell. The Blood cells have no nucleus so they are considered Prokaryotic. That is also why they cannot divide and they do not live very long. The other cells are all Eukaryotic.Added:The above is totally wrong. Red blood cells may have no nucleus, as they mature to not have one, but they are still eukaryotic cells and all animal cells are eukaryotic.
What does one long strand of DNA would be found in what?
One long strand of DNA would be found in the nucleus of eukaryotic cells, where it is organized into structures called chromosomes. In prokaryotic cells, such as bacteria, DNA exists as a single circular strand located in a region called the nucleoid. Additionally, DNA can also be found in the mitochondria and chloroplasts of eukaryotic cells, where it is involved in energy production and photosynthesis, respectively.
