Web4 okt. 2024 · Chromosome Definition A chromosome is a string of DNA wrapped around associated proteins that give the connected nucleic acid bases a structure. During interphase of the cell cycle, the chromosome exists in a loose structure, so proteins can be translated from the DNA and the DNA can be replicated. WebSuch is the current state of Huntington's disease (HD), an adult-onset autosomal dominant disorder. Today, researchers can literally "measure" the HD-associated gene , called huntingtin ( HTT ), by determining the number of repeats of a set of three specific bases within this gene.
