Webb16 juni 2024 · Ribonucleic acid (RNA) is a molecule consisting of a long linear chain of nucleotides. Each nucleotide unit is comprised of a ribose sugar, a phosphate group and a nitrogenous base (also called nucleobase ). Ribose is a pentose sugar whose carbons are numbered 1′ through 5′. The phosphate group is connected to the 3′ of the ribose and the … WebbParkinson’s disease (PD) is a neurodegenerative disorder characterized by fibrillar cytoplasmic aggregates of α-synuclein (i.e., Lewy bodies) and the associated loss of dopaminergic cells in the substantia nigra. Mutations in genes such as α-synuclein (SNCA) account for only 10% of PD occurrences. Exposure to environmental toxicants including …
