because it has its own modification and restriction system which prevents its own DNA from degradation as telomeres are mainly responsible to protect the DNA from exonuclease activity of DNase.
In prokaryotes, their chromosomes are circular, so they do not have ends; thus, they do not have telomeres.
Prokaryotes don't have chromosomes, only circular DNA. Prokaryotes have no telomeres because DNA have no ends.
The telomere is the protective cap of DNA on the tip of chromosomes. You lose a small amount of these telomeres each time the cell divides. Eventually the telomeres be lost as you age. Short chromosomes because of lack telomeres are one reason aging occurs.
There are two telomeres for each chromosome, so you need to figure out how many chromosomes there are at each stage and multiply that by two. G1-- growth phase: 14 chromosomes = 28 telomeres G2-- growth phase after replication in S phase: 28 chromosomes= 56 telomeres Mitotic Prophase-- before cell division, nuclear membrane disappears: 28 chromosomes= 56 telomeres Mitotic telophase-- nuclei separate: 14 chromosomes = 28 telomeres
Chromosomes
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.
During mitosis and meiosis, kinetochores move chromosomes across the spindle fibers. The kinetochores serve as vehicles and the fibers serve as roads.

Telomeres.
No
No,they do not have.They have plasmids.Only eukariyotes have chromosomes.
Histone
Chromosomes are only in eukariyotes.Can not be seen in prokariyotes.
Telomerase is an enzyme that adds nucleotides to the ends of telomeres in chromosomes. They do not solve any problems in replication
Prokaryotic organisms such as Bacteria have circular form of chromosomes
Eukaryotic chromosomes are formed primarily of chromatids and telomeres
