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.

Eukaryotic DNA sequences called enhancers have a function similar to the of prokaryotic operons?
Eukaryotic DNA sequences called enhancers have a function similar to the operators of prokaryotic operons. In eukaryotic cells, repressor proteins inhibit transcription by binding to silencers.
What are pair of similar chromosomes called?
HomologousWe receive one complete set of chromosomes from each parent. This means that for each chromosome, say chromosome 7, there are two copies in every cell of our bodies: the maternal and paternal copies of chromosome 7.The two copies of one chromosome are called a pair of homologous chromosomes.
Are prions prokaryotic?
No. Prions are neither prokaryotic nor eukaryotic. They are similar to viruses - nonliving. However, they are more "nonliving" than viruses in the respect that they are just protein sans nucleic acid or anything cell-like.
What are chromosomes that have similar genetic information called?
Chromosomes that are similar are called homologous chromosomes. Chromosomes that have similar paired genes are called homolegous chromosomes. These copies have the same loci. These loci provide points along each chromosome that enable a pair of chromosomes to align.
How are human chromosomes 21 and 22 similar?
Chromosomes 21 and 22 are the smallest human autosomes. Chromosome 22 contains approximately 43 million DNA base pairs. Chromosome 21 contains roughly 32 million base pairs. These were the first two hu8man Chromosomes whose sequences were determined.
Eukaryotic DNA sequences called enhancers have a function similar to the of prokaryotic operons?
Eukaryotic DNA sequences called enhancers have a function similar to the operators of prokaryotic operons. In eukaryotic cells, repressor proteins inhibit transcription by binding to silencers.
Similarities and differences between prokaryotic and eukaryotic cells?
The similarities between prokaryotic and eukaryotic cells include that they both have vesicles and vacuoles. The differences between them include the fact that eukaryotic cells have a nucleus, mitochondria and a cytoskeleton whereas prokaryotic cells do not.
What are the similarities of prokaryotes and eukaryotes?
Prokaryotic and eukaryotic cells are similar in which of the following ways?
What eukaryotic organelle is functionally similar to the prokaryotic cell membrane and its infoldings?
Hup li
How are autosomes similar to sex chromosomes?
Sex chromosomes and autosomes are from the same chromosome, The chromosome has 46 chromosomes and 2 of them are sex chromosomes and the rest are called autosomes
How are are binary fission and mitosis similar how are they different?
they are different because Binary is a prokaryotic cell and mitosis is a eukaryotic.
Whats the same about eukaryotic cells and prokaryotic cells?
Prokaryotic and eukaryotic cells are similar in which of the following ways?
What are pair of similar chromosomes called?
HomologousWe receive one complete set of chromosomes from each parent. This means that for each chromosome, say chromosome 7, there are two copies in every cell of our bodies: the maternal and paternal copies of chromosome 7.The two copies of one chromosome are called a pair of homologous chromosomes.
How are prokaryotic cells and eukaryotic cells similar?
Both are cells. Both contain ribosomes, DNA......
Three things both eukaryotic and prokaryotic cells have?
The similarities between prokaryotic and eukaryotic cells are; They both contain ribosomes They are both enclosed by plasma membranes They are both filled with cytoplasm and they both have DNA.
Which is used as evidence for the idea that multicellular organisms evolved from prokaryotes?
Mitochondria and chloroplasts have their own DNA
Homologous chromosomes are similar but not identical?
homologous chromosomes are chromosome pairs that code for the same features such as eye color or hair color, one chromosome of the pair comes from your mom and one from your dad so no they are not identical
