This is a big hint about one of the differences between these two cell types. Prokaryotic cells have no nuclei, while eukaryotic cells do have true nuclei. This is far from the only difference between these two cell types, however. A eukaryotic cell contains a number of chromosomes; a prokaryotic cell contains only one circular DNA molecule and a varied assortment of much smaller circlets of DNA called plasmids.. 2  The smaller, simpler prokaryotic cell requires far fewer genes to operate than the eukaryotic cell.
Most women and men with chlamydia do not have symptoms. The time between exposure to chlamydia and the start of symptoms-the incubation period-may range from days to months. If symptoms appear, it is usually 1 to 3 weeks after sexual contact with an infected person.
Chlamydia is spread from person-to-person during unprotected sex. It can be passed through vaginal, anal, and oral sex. It can also be passed to the eye by a hand or other body part moistened with infected secretions. Chlamydia can be passed from a woman infected with chlamydia to her fetus during birth. Chlamydia cannot be spread by kissing, toilet seats, bed linens, doorknobs, swimming pools, hot tubs, bathtubs, sharing clothes, or eating utensils. Reply.
