Nucleic acid hybridization natural positions within a chromosome). In 1969, the two scientists published a paper demonstrating that radioactive copies of a ribosomal DNA sequence could be used to detect complementary DNA sequences in the nucleus of a frog egg. Since those original observations, many refinements have increased the versatility and sensitivity of the procedure to the extent that in situ hybridization is now considered an essential tool in cytogenetics. Nucleic acid hybridization In molecular biology, hybridization (or hybridisation) is a phenomenon in which single-stranded deoxyribonucleic acid (DNA) or ribonucleic acid (RNA) molecules anneal to complementary DNA or RNA. Though a double-stranded DNA
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
