DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Environmental factors significantly impact gene expression through epigenetic modifications

Epigenetics, the study of changes in gene function that do not involve alterations to the DNA sequence, plays a pivotal role in understanding the complex interplay between genetics and the environment. The review article "Epigenetics and Environmental Health" provides an in-depth analysis of how epigenetic modifications can influence the onset and progression of various diseases, particularly cancer and cardiovascular diseases.

Overcoming CRISPR's side effects for therapeutic applications

CRISPR is a revolutionary tool that allows scientists to precisely modify the genome and gene expression of cells in any organism. It's a reagent - a substance that facilitates a reaction - that combines an enzyme with a programmable RNA capable of locating specific genetic sequences. Once guided to the correct spot, the enzyme acts like a pair of scissors, cutting, replacing, or deleting sequences of DNA.
