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.)
How long should antiviral drugs be taken? To treat the flu, oseltamivir and zanamivir are usually prescribed to be taken twice daily for 5 days, although people hospitalized with the flu may need antiviral treatment for longer than 5 days. Peramivir is given one time intravenously over a period of 15 to 30 minutes. Top of Page
