The nurse would most likely disagree with the patient. Pap smear is a diagnostic test that screens pre-cancerous or cancerous cells on the cervix, which is the opening of the uterus. It is recommended for women starting from the age 21 to regularly undergo this test, especially when sexually active. For the 49 year-old patient, she needs to undergo Pap smear test every 3 to 5 years. The patient should note that this test is used to track any abnormal cells in the cervix. When they do, early treatment would still be done in the hospital before it becomes even more serious. Hence, whether the patient took Pap smear tests regularly, she would still need the help of the hospital to treat it. It would only differ in the time of admittance.
Answer:
The 5' end has free phosphate group while the 3' end has free OH group.
Explanation:
Each DNA strand has two ends that differ from each other with respect to the functional group. The nucleotide present at the 5' end of a DNA strand has a free phosphate group. This phosphate group of other nucleotides of the DNA strand is bonded in phosphodiester bonds. Likewise, the 3' end of a DNA has a free OH group. This makes the two ends of a DNA strand quite different from each other. A DNA new nucleotide can be added to the 3' end due to the presence of a free OH group.
