Nucleic acid sequence Nucleic acid sequence A nucleic acid sequence is a succession of letters that indicate the order of nucleotides forming alleles within a DNA (using GACT) or RNA (GACU) molecule. By convention, sequences are usually presented from the 5' end to the 3' end. For DNA, the sense strand is used. Because nucleic acids are normally linear (unbranched) polymers, specifying the sequence is equivalent to defining the covalent structure of the entire molecule. For this reason, the nucleic acid sequence is also termed the primary structure. The sequence has capacity to represent information. Biological deoxyribonucleic acid represents the information which directs
Acetic acid (medical use) 25 USD. Acetic acid is more commonly used for external ear infections in the developing world than the developed. Acetic acid may be applied to the cervix to help detect cervical cancer during screening in many areas in the developing world. Acetic acid is applied to the cervix and if an area of white appears after about a minute the test is positive. Acetic acid (medical use) Acetic acid, which at low concentrations is known as vinegar, is used as a medication to treat a number of conditions. As an eardrop it is used to treat infections of the ear
