Respuesta :
By deacetylating the histone tails, the DNA becomes more tightly wrapped around the histone cores, making it harder for transcription factors to bind to the DNA. This leads to decreased levels of gene expression and is known as gene silencing.
What is DNA?
The hereditary substance in humans and virtually all other animals is DNA, or deoxyribonucleic acid. Almost single cell in a person's body contains the same DNA. DNA is composed of molecular building components known as nucleotides. These building blocks are composed of three components: a phosphate group, a sugar group, and one of four different forms of nitrogen bases. Nucleotides are linked together in chains, with the phosphate and sugar groups alternating. DNA is an organic molecule that includes genetic information as well as instructions for protein creation. It can be present in the majority of cells in all organisms. DNA is an important component of reproduction in which genetic inheritance is passed down from parent to offspring.
