USLME Biochem - First Aid Exam Questions With Accurate Answers. Chromatin structure - answerDNA exists in condensed chromatin form in order to fit in nucleus Negatively charged DNA loops twice around positively charged histone octamer (2 sets of H2A, H2B, H3 and H4) to form nucleosome "bead" Octomer subunits consist primarily of lysine and arginine amino acids (positively charged). H1 ties nucleosome beads together in a string Heterochromatin - answerCondensed, transciptionally inactiv...

Most of the inherited changes in our DNA arise because of unavoidable endogenous errors in cellular mechanisms and harmful effects of certain natural molecules and atoms within our cells correct answers True Most of the inherited changes in our DNA arise because of exposure to extracellular mutagens, including radiation sources and chemical mutagens. correct answers False Errors in DNA replication and DNA repair are a major source of mutations in our cells. correct answers True Signific...
