Your DNA is what makes you uniquely you. It's that double helix that your genes are made of. Your DNA accounts for why you resemble your parents and it distinguishes you from your pet frog and from everybody else. DNA stands for deoxyribonucleic acid, sometimes called the molecule of life, as almost all organisms have their genetic material codified as DNA. Since each personâs DNA is unique, DNA typing is a valuable tool in connecting suspects to crime scenes.
Most of the time, a cold or the flu will resolve on its own, with time. There are prescription drugsâTamiflu and Relenzaâthat can treat the flu if given within two days of getting sick. (These are recommended for those at high risk of flu complications, such as infants, the elderly, and people with weak immune systems, among others, and most otherwise-healthy people don't need them.)
Tamiflu (oseltamivir) and another prescription drug called Relenza (zanamivir) are approved by the Food and Drug Administration to treat the flu. Unlike flu drugs you can buy without a prescription, Tamiflu and Relenza don't just treat flu symptoms but can shorten how long you have the illness, by inhibiting the growth of the virus. And they can reduce the risk of complications such as pneumonia and respiratory failure, if you take them within 48 hours of the onset of symptoms.
