Scientists have mapped out the molecular structure of a key part of our chromosomes called telomeres, which play a pivotal part in aging and cancer. Scientists from Nanyang Technological ...

When people think of DNA, they usually think of genes, the parts that code for proteins and drive inherited traits. But there ...

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA—its genome—and segregate it equally ...

If measured from beginning to end, the DNA in our cells is too long to fit into the cell's nucleus, explaining why it must be ...

A deeper understanding of how DNA changes over generations helps scientists learn why people differ and how diseases develop. Until recently, many fast-changing parts of the human genome remained ...

New imaging tools reveal how within an hour of infection, the virus begins to alter our chromosomes to kick-start its own replication.

DNA is a resolutely three-dimensional molecule.In animals and plants, long strands are coiled and folded into chromosomes, which store genetic information inside the nucleus of a body’s cells.

Cytosine is one of the four main nitrogenous bases found in DNA and RNA, along with adenine (A), guanine (G), and thymine (T) or uracil (U). It is a pyrimidine derivative, meaning it has a single-ring ...

Studying how single DNA molecules behave helps us to better understand genetic disorders and design better drugs. Until now however, examining DNA molecules one-by-one was a slow process.
