What are the key differences between prokaryotic chromosomes and eukaryotic chromosomes in terms of structure and organization?
Prokaryotic chromosomes are simpler and circular, found in the cytoplasm, while eukaryotic chromosomes are more complex and linear, found in the nucleus. Eukaryotic chromosomes are organized with histone proteins into chromatin, while prokaryotic chromosomes lack histones.
How do prokaryotic cells differ from eukaryotic cells?
Prokaryotic cells do not have a membrane-bound nucleus or other organelles, while eukaryotic cells have a nucleus and membrane-bound organelles. Prokaryotic cells are generally smaller and simpler in structure compared to eukaryotic cells. Additionally, prokaryotic cells typically have a single circular chromosome, while eukaryotic cells have multiple linear chromosomes.
What do eukrayotic calls have that prokaryotic cells do not?
Eukaryotic cells have a true nucleus, membrane-bound organelles, and a more complex internal structure compared to prokaryotic cells. Additionally, eukaryotic cells are typically larger and have multiple linear chromosomes, whereas prokaryotic cells have a single circular chromosome.
Name two differences between the heredity material of a prokaryotic cell and a eukaryotic cell?
Prokaryotic cells have a single circular chromosome, while eukaryotic cells have multiple linear chromosomes. Prokaryotic cells lack a nucleus and their DNA is not associated with histone proteins, whereas eukaryotic cells have a nucleus where their DNA is stored and packaged with histone proteins.
How does the structure of chromosomes in prokaryotic cells and eukaryotic cells affect the DNA replication processes in a cell?
In prokaryotic cells, which have a single circular chromosome, replication initiates at a single origin of replication and proceeds bidirectionally until the entire chromosome is copied. In contrast, eukaryotic cells have multiple linear chromosomes that replicate from multiple origins of replication simultaneously. The linear nature of eukaryotic chromosomes poses challenges during replication, such as the need to overcome end-replication problem and preserving telomeres.
What structure is DNA found in?
DNA is found in the nucleus of eukaryotic cells, where it is tightly packaged into chromosomes. In prokaryotic cells, DNA is found in the nucleoid region, a less organized structure than eukaryotic chromosomes.
What are the differences between prokaryotic nucleoid and eukaryotic nucleus?
In prokaryotic cells DNA is present in the bacterial chromosome. This chromosome forms the nucleoid. The nucleoid is the mass of DNA that makes up the chromosome of cells Archaea and bacteria. The nucleus is a structure enclosed in a membrane containing the chromosomes of eukaryotic organisms. In other words the eukaryotic cell has a nucleus but the prokaryotic does not.
How does the structure of a chromosome differ in a prokayote and eukaryote?
Eukaryotic cells have a double membrane, surrounding the nucleus, the organelle that contains several chromosomes. The prokaryote chromosomes are dispersed within the cell and is not enclosed by a separate membrane
What are 5 differences between prokaryotics and eukaryotics?
prokaryotic:-1 True nucleus not present. 2 membrane bound organelles are lacking. 3 size- 1-10mm 4 single chromosomes. 5 nucleus absence. Eukaryotic:- 1True nucleus present. 2 organelles are membrane bounded. 3 size- 5-100mm 4 more than 1 chromosomes. 5 nucleus present.
In a eukaryotic cell what is one of the structures in the nucleus that is made up of DNA and protein in a prokaryotic cell is the main ring of DNA?
In a eukaryotic cell, the structure made up of DNA and proteins in the nucleus is the chromosome. In prokaryotic cells, the main ring of DNA is called the nucleoid, which lacks a membrane-bound nucleus.
How prokaryotes chromosomes differ from eukaryote?
A prokaryotic chromosome consists of a single molecule of DNA in the form of a closed loop. The chromosome is described as circular. A prokaryotic cell has only one chromosome. A eukaryotic chromosome is linear, not circular, in other words it has two ends, like a sausage. Each chromosome contains one molecule of DNA for the first half or so of interphase, then the DNA replicates, and the two DNA molecules remain together (as sister-chromatids) in the same chromosome for the rest of interphase. This does not happen in prokaryotic cells. Eukaryotic cells have more than onechromosome. A further difference: prokaryotic chromosomes consist only of a naked DNA molecule, but eukaryotic chromosomes also contain many molecules of proteins (mostly histones). The DNA is wound around these proteins.
Michelle has been given a microscope slide that contains a eukaryotic cell and a prokaryotic cell What should she look for to distinguish the eukaryotic cell from the prokaryotic cell?
Michelle can look for several distinguishing features: eukaryotic cells typically have a nucleus, membrane-bound organelles, and are generally larger and more complex compared to prokaryotic cells. On the other hand, prokaryotic cells lack a defined nucleus and membrane-bound organelles, often have a cell wall, and are generally smaller and simpler in structure. Additionally, eukaryotic cells may have multiple linear chromosomes while prokaryotic cells typically have a single circular chromosome.
