Encoded within this DNA are the directions for traits as diverse as the color of a person's eyes, the scent of a rose, and the way in which bacteria infect a lung cell. DNA is found in nearly all ...

cell organelles include mitochondria, ribosomes and chloroplasts in plants. Cytoplasm, ribosomes present; there are no mitochondria or chloroplasts. Genetic material DNA in a nucleus, plasmids are ...

The transfer of this principle to artificial cells is a challenge in synthetic biology. Advances in DNA nanotechnology now offer promising solutions. They allow the creation of novel transport ...

Along the way you'll also see the intricate bending and winding that takes place within a chromosome, which allows more than five feet of DNA to fit within the nucleus of a tiny cell.

Replication of DNA DNA replication is the process by which a cell makes an identical copy of its DNA. Gene expression Only a fraction of the genes possessed by any particular cell will be expressed.

While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows.

Unleashing the patient's immune system to kill cancer cells and clear tumors is a major goal of cancer treatment. "The surprising result of our research is that DNA repair, which normally protects ...
