Genetically speaking, prokaryotes are different from eukaryotes because (1 of 2) a.prokaryotes usually have one main circular chromosome, whereas eukaryotes have multiple linear chromosomes. b.many prokaryotes do not have histone proteins to package their DNA. c.prokaryotes do not have a nucleus to house their DNA as eukaryotes do. d.prokaryotes have less total DNA than do eukaryotes. e.All of the above.

Compare and contrast the similarities and differences between eukaryotic and prokaryotic DNA. a. Eukaryotes have a single, circular chromosome, while prokaryotes have multiple, linear chromosomes. Prokaryotes pack their chromosomes by super coiling, managed by DNA gyrase. Eukaryote chromosomes are wrapped around histone proteins that create heterochromatin and euchromatin, which is not present in prokaryotes. b. Prokaryotes have a single, circular chromosome, while eukaryotes have multiple, linear chromosomes. Prokaryotes pack their chromosomes by super coiling, managed by DNA gyrase. Eukaryote chromosomes are wrapped around histone proteins that could form heterochromatin, which is not present in prokaryotes. c. Prokaryotes have a single, circular chromosome, while eukaryotes have multiple, linear chromosomes. Eukaryotes pack their chromosomes by super coiling, managed by DNA gyrase. Prokaryotes chromosomes are wrapped around histone proteins that could form heterochromatin, which is not present in eukaryotes. d. Prokaryotes have a single, circular chromosome, while eukaryotes have multiple, linear chromosomes. Prokaryotes pack their chromosomes by super coiling, managed by DNA gyrase. Eukaryote chromosomes are wrapped around histone proteins that could form heterochromatin, which is present in prokaryotes.
In order to fit within a cell, DNA becomes more compact by breaking apart into separate genes, extending to form very long, thin molecules, wrapping tightly around associated proteins, and being enzymatically changed into a protein. Chromatids are dense patches within the nucleus, bacterial chromosomes, joined strands of duplicated genetic material, prokaryotic nuclei. The protein disk that attaches two chromatids to each other in a chromosome is called a(n) chloroplast, centromere, gamete, centriole. Which of the following is not a true difference between the chromosomes of eukaryotes and those of prokaryotes? Eukaryotic chromosomes are linear, while those of prokaryotes are circular. Eukaryotic chromosomes are associated with histones, while those of prokaryotes are not. Eukaryotes usually have more than one chromosome, while prokaryotes have only one chromosome. Eukaryotic chromosomes contain DNA, while prokaryotic chromosomes contain a different form of genetic material. The chromosomes in your body exist in 23 pairs, each contain thousands of genes, are about 40 percent DNA and 60 percent protein. All of the above.

Which of the following is a correct statement about the genomes of prokaryotes? Prokaryotic chromosomes are sometimes called "genochromes." Prokaryotic cells have multiple chromosomes packaged with a relatively large amount of protein. Prokaryotic genomes are composed of circular chromosomes of DNA. Instead of a nucleus, prokaryotic cells have a "nucleoid" region. Prokaryotic genomes are haploid throughout most of the cell cycle.
