> do bacteria have telomeres?
Linear chromosomes, due to the nature of DNA polymerase, shorten after
every successive replication by a couple bases. Therefore those organisms
with linear chromosomes have an enzyme call telomerase which adds
repetative sequences onto the ends of the chromosomes called telomeres so
no genes are lost by the shortening of the chromosomes.
Since it's the eucaryotes that have the linear chromosomes not the
eubacteria (ie bacteria) which have circular chromosomes,
bacteria do not have telomeres.
