Particles functionalized with deoxyribonucleic acid (2), polysaccharides (3), or glycoproteins (4, 5) are used in a wide variety of applications, including gene therapy and pathogen-specific antibiotic and tumor-selective chemotherapeutic delivery.
Also, regucalcin has been demonstrated to transport into the nucleus of cells, and it can inhibit nuclear protein kinase, protein phosphatase, and deoxyribonucleic acid and ribonucleic acid synthesis.
Although by then scientists understood that deoxyribonucleic acid was most likely the molecule of life, absolute certainty eluded them, because key components were still missing.
