People in an Iowa family affected with an early-onset autosomal dominant form of Parkinson disease have a triplication of the alpha-synuclein gene (SNCA) on chromosome 4q21.This may be another genetic route to PARK1. PARK1 is an autosomal dominant trait and is due to mutation in the alpha-synuclein gene (SNCA) on chromosome 4q21; 2  PARK2 is an autosomal recessive trait and is due to mutation in the gene encoding parkin on chromosome 6q25.2-q27; 3  PARK3 is an autosomal dominant trait and is due to a gene on chromosome 2p13;
Nucleotides are the true building blocks of DNA. There are three components of a single nucleotide: one deoxyribose sugar, one phosphate, and one of the four bases. To make a complete DNA molecule, single nucleotides join to make chains that come together as matched pairs and form long double strands.This article walks you through the assembly process.here are three components of a single nucleotide: one deoxyribose sugar, one phosphate, and one of the four bases.
