Beyond the ladder-like structure described above ... Eukaryotes accomplish this feat by wrapping their DNA around special proteins called histones, thereby compacting it enough to fit inside ...

The information DNA contains is the instructions that the cell uses to make proteins. Proteins play a big part in determining the characteristics of specialised cells and whole organisms.

Histones are a family of small, positively charged proteins termed H1, H2A, H2B, H3, and H4 (Van Holde, 1988). DNA is negatively ... and not quite the uniform structure depicted in instructive ...

The sequence of amino acids in the chain determines how the chain will fold up to make the protein, so different proteins have different three-dimensional shapes. The three-dimensional shape of a ...

Every cell in your body contains the same genetic sequence, yet each cell expresses only a subset of those genes. These ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single-stranded RNA and a double ... It states that the genetic ...

ChromoGen: A quick method to determine 3D genomic structures using generative AI, enabling the prediction of thousands of ...

The new finding is published in Cell in an article titled, “ SMC motor proteins extrude DNA asymmetrically and can switch directions ,” and is key to understanding how these motors shape our genome ...

Rock and dust samples retrieved by NASA from the asteroid Bennu exhibit some of the chemical building blocks of life, ...

New AI model takes minutes rather than days to predict how a specific DNA sequence will arrange itself in the cell nucleus.

A new mega-database of half a million mutations may flag new ways of treating genetic disease, scientists say.

Scientists develop DNA nanorobots capable of modifying artificial cells. Scientists at the University of Stuttgart have successfully used "DNA origami" to control the structure and function of ...
