WebThis means that that when you look (after staining) at the condensed chromosomes in a cell you can see chromosomes with chromatids that look like they only have one arm, others that have one long and one short arm, and some that will look like the two arms are of … WebDNA can unwind from histones. When DNA is wrapped around histones, the genes cannot be transcribed into RNA (and, eventually in protein). So these enzymes come along called HATs, which chemically modify the histones in effect loosening their grip on the DNA. read file into buffer c++
