DNA strand. Computer artwork showing the double helix structure of a DNA (deoxyribonucleic acid) molecule. Each strand consists of a sugar-phosphate backbone attached to nucleotide bases. DNA contains sections called genes that encode the body's genetic information. The orange glow is depicting a CRISPR-Cas9 gene editing complex. The CRISPR-Cas9 protein is used in genome engineering to cut and replace certain sections of DNA. DNA is composed of two strands twisted into a double helix. The background shows generic molecules.
