Ribonucleic acid (RNA) (yeast) is a ribonucleic acid isolated from yeast, characterized as a polynucleotide containing primary and secondary phosphate groups, amino groups, and purine-pyrimidine hydroxyl groups per 4 corrected phosphorus atoms. Ribonucleic acid (yeast) is widely used in scientific research as a substrate for nuclease detection, a carrier in ethanol precipitation processes, and a standard control for molecular biology techniques.
