Which organisms have circular chromosomes?
Prokaryotic organisms such as Bacteria have circular form of chromosomes
How are prokaryotic and eukaryotic alike and diffrent?
Prokaryotic cells have no nuclei and eukaryotic cells have a true nuclei. prokaryotic DNA is circular where eukaryotic DNA is linear.
How is eukaryotic chromosomes similar to a prokaryotic chromosome?
Simplified version that an intro biology course would look for: Eukaryotes have multiple pairs of linear chromosomes. The gene-coding sequences are interspersed with non-coding regions that may control gene regulation. Within a gene sequence, there are exons (coding regions) and introns (non-coding regions that will be removed from the mRNA). Prokaryotic chromosomes are tightly wrapped around proteins called histones. Eukaryotic chromosomes are contained in a nucleus. Prokaryotes have 1 circular chromosome, and may have smaller extrachromasomal DNA in the form of plasmids. Prokaryotic DNA does not have the non-coding regions or introns. Bacteria do not have histones, but archaea have histone-like structures associated with their chromosomes. Prokaryotic chromosomes exist in the cytoplasm. Reality about Bacterial Chromosomes: Although many have only the 1 circular chromosome, there are many exceptions to this rule Borrelia burgdoferi (corkscrew-shaped bacteria that causes Lyme Disease) has 17 linear chromosomes and many plasmids.
What is a circular chromosome?
A circular chromosome is, essentially, exactly what it sounds like: a chromosome (strand of DNA that carries the genetic information of an organism) that is circular. Circular chromosomes are found in prokaryotes such as bacteria, as well as in mitochondria and chloroplasts. Eukaryotic cells, on the other hand, typically have chromosomes that are linear, meaning they have two ends that do not connect.
How DNA control cellular functions?
The chromosome(s). In eukaryotic cells there are several linear chromosomes enclosed in an organelle called the nucleus. In prokaryotic cells there is one circular chromosome and several tiny circular plasmids, but no nucleus.
Which organisms have circular chromosomes?
Prokaryotic organisms such as Bacteria have circular form of chromosomes
DNA in Eukaryote long and linear?
DNA in Eukaryotic cells are linear. DNA in Prokaryotic cells are circular.
How are prokaryotic and eukaryotic alike and diffrent?
Prokaryotic cells have no nuclei and eukaryotic cells have a true nuclei. prokaryotic DNA is circular where eukaryotic DNA is linear.
Is DNA present in both prokaryotic cells and eukaryotic cells?
Eukaryotic DNA is linear, whereas most prokaryotic DNA is circular.

The chromosomes of eukaryotic cells have more what than do the chromosomes of prokaryotic?
The chromosomes of eukaryotic cells have more DNA than the chromosomes of prokaryotic cells. Prokaryotes usually only have 1 circular chromosome and no "junk DNA", while eukaryotes are multi-chromosomal.
The chromosomes of eukaryotic cells have more what than do the chromosomes of prokaryotic cells?
The chromosomes of eukaryotic cells have more DNA than the chromosomes of prokaryotic cells. Prokaryotes usually only have 1 circular chromosome and no "junk DNA", while eukaryotes are multi-chromosomal.
How do chromosomes function in a prokaryotic cell?
In a prokaryote there is no designated nucleus and the genetic mass is free floating. As there is one chromosome it is circular.
Prokaryotes have what kind of DNA molecule?
prokaryotic DNA is "naked," meaning that it has no histones associated with it, and it is not formed into chromosomes
Why plasmid are circular?
Plasmids are genetic structures in a cell that can replicate independently of the chromosomes. They are circular because linear DNA requires a way to copy its ends.
How many chromosomes do they contain?
Bacteria contain one circular chromosome (and several tiny circular plasmids), some slime molds contain hundreds of thousands of linear chromosomes. Other organisms contain various numbers of chromosomes depending on the species.
Is protists DNA linear or circular?
Straight(isn). It's not circular, the DNA is organized in chromosomes like eukaryotes. So circular is not correct, since that applies to things like bacteria and mitochondria.
