2 авг. 2018 г. · Being circular, prokaryotic DNA behaves kind of like a giant plasmid. Most circular DNA is supercoiled, either negatively or positively.

12 нояб. 2018 г. · Actually histones are there in some prokaryotes (i.e. archea).Histones in eukaryotes help store the DNA in condensed form (i.e. nucleosomes).

4 дек. 2020 г. · Yes. All cells have at least one chromosome. Prokaryotes typically have one circular chromosome made up of double stranded DNA and lots of plasmids.

2 сент. 2019 г. · Prokaryotes lack a nucleus to store their DNA, which instead is found free in the cytoplasm in a circular form (called genophore) within the cytoplasm.

30 июн. 2017 г. · Do prokaryotes have a nucleus? No prokaryotes lacks nucleus.In addition to not having a nucleus, prokaryotic cells do not have nuclear ...

11 нояб. 2021 г. · A basic repeating unit of DNA organization is the nucleosome, in which DNA is wrapped around eight histone proteins. In eukaryotes a chromosome ...

13 мая 2017 г. · These cells has incipient nucleus and do not possess nuclear membranes. Hence the genetic material of the cell is just scattered in the cell.

28 сент. 2017 г. · While Eukaryotes have special proteins called histone to package nuclear DNA into smaller spaces, prokaryotes do that with the mechanism of supercoiling.

4 авг. 2020 г. · Nucleosome model is a scientific model which explains the organization of DNA and associated proteins in the chromosome.

10 мая 2016 г. · Prokaryote chromosomesare (typically) one or more strings of circular DNA(the DNA proper called a nucleoid), free-floating in the cytosol.
