WebWhen 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. This allows the transcriptional machinery access to the DNA, creating RNA (and, eventually, protein). WebThe DNA wrapped around histones is further organized into higher-order structures that give a chromosome its shape. For most of the life of the cell, chromatin is decondensed , …

WebStrands of the backbone of DNA are parallel. false Uridine is a nucleotide in DNA false Replication of DNA is semi-conservative. true The DNA polymerase that replicates the parental strand of DNA reads the parental DNA from 5' to 3" and makes a new DNA strand from 3' to 5' DNA replication in eukaryotes is sped up by multiple origins of replication. WebHistones act like “spools” around which DNA is wrapped. In humans, each cell contains approximately 2 meters of DNA; however, because of the wrapping of DNA around histones, the condensed DNA is approximately 120 micrometers long! This DNA “packaging” in the form of chromatin plays a key role in the regulation of gene expression.
