Why do bacteria not have telomeres

Prokaryotes don't have chromosomes, only circular DNA. Prokaryotes have no telomeres because DNA have no ends. I dont really know, i need to find out about it for my homework!! We all begin as 1 cell and as it divides the telomeres become shorter. Larger people have more cells than smaller people and therefore have shorter telomeres. As telomeres get shorter a cell loses the ability to divide. There are many interesting facts about telomeres. It is a region of very repetitive DNA at the end of a chromosome.

They are usually only active in germ cells. Telomeres are made up of six nucleotide bases. No, bacteria are not vertebrates as they dont have a back bone. No they dont IDK i dont know but hurry up i need it for science class!!!!!!!!!!!!!! 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. Iam sorry i dont know ahahahahaha. No, bacteria does not need nitrogen, but only bacteria is capable of fixing nitogen into the usable form.

Why do prokaryotic chromosomes not have telomeres? How is bacteria used in agriculture? What is planktons favorite food? Is obesity related to telomeres? Without telomeres, important DNA would be lost every time a cell divides usually about 50 to 70 times. Both prokaryotic and eukaryotic cells are capable of repairing mismatched base pairs in their DNA. Candidates include vitamin D, omega-3 fatty acids, and TA, a product that purportedly contains extracts of astragalus membranaceus, a plant-based compound that demonstrates immunomodulatory, anti-oxidative stress, and anti-aging effects, the latter of which are associated with longer telomeres.

This is because each time a cell undergoes mitosis, the telomeres on the ends of each chromosome shorten. This is why some experts believe that retinol can actually speed up aging, by shortening the cell renewal cycle. Why do telomeres get shorter? Your DNA strands become slightly shorter each time a chromosome replicates itself. Telomeres help prevent genes from being lost in this process. But this means that as your chromosomes replicate, your telomeres shorten. Several extracts from the Astragalus membranaceus root have been studied as possible telomerase activators 22— Such an extract is TA, a natural product telomerase activator marketed since , that has been found to lengthen telomeres in humans The telomeres are special structures on the chromosome ends that are essential for providing protection from enzymatic end-degradation and maintaining chromosomal and genomic stability.
