Laying the Groundwork: Levene Investigates the Structure of DNA Meanwhile ... In other words, the total amount of purines (A + G) and the total amount of pyrimidines (C + T) are usually nearly ...

The novel feature of the structure is the manner in which the two chains are held together by the purine and pyrimidine bases. The planes of the bases are perpendicular to the fibre axis.

HPRT1, involved in the purine salvage pathway, likely becomes essential due to ... and 13 in galactose condition (Fig. 3D). In glucose media, 56 interactions out of the 2286 possible SLC-enzyme pairs ...

Earth—our tiny blue dot in the galaxy—is approximately 26,000 light years away from a fascinating and active region of the ...

NASA's James Webb Space Telescope made its public debut with a series of breathtaking images. Among them was an ethereal ...

Understanding how dislocations (line defects in the crystal structure) occur when 3D-printing metals has been unclear to materials scientists. Understanding when and how dislocations form in ...

But just as hope seems lost, a wave of innovation is crashing into the depths: 3D-printed reefs. These artificial structures are turning the tide in marine conservation, combining cutting-edge ...

MTX acts as a folate antagonist and interrupts the synthesis of purines and pyrimidines, as well as the remethylation of homocysteine to form methionine, and multiple methyltransferase enzymes.

The collective, led by architect and biodesigner Andrea Shin Ling, has created a fascinating exhibition consisting of several 3D printed living structures embedded with live cyanobacteria, a type of ...

Deciphering those structures experimentally is a time-consuming process, making it difficult to compare the 3D genome structures found in different cell types. MIT Professor Bin Zhang is taking a ...

What if a 3D printing defect could become the key to developing a new ... Using the DLP process, they have managed to replicate anisotropic structures similar to those of the legs of these reptiles, ...
