Scientists still needed to figure out this molecule's structure to be sure, and to understand how it worked. In 1948, Linus Pauling discovered that many proteins take the shape of an alpha helix ...

to argue that DNA actually takes the form of a double helix, a ladder-like structure that is twisted along its entire length (Figure 6). Franklin, Watson, and Crick all published articles ...

based on the three-dimensional structure of the tRNA molecule. Other classes of RNA species include microRNAs, small interfering RNAs, and sRNAs—all of which are not translated into proteins but ...

The two strands of the DNA helix are unzipped ... the correct shape and becomes a protein. Peptide bonds form between the adjacent amino acids to finalise the structure.

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single ... which is then translated into proteins. This process is ...

University of Iowa-led study has revealed the unexpected structure adopted by the DNA repair protein RAD52 as it binds and protects replicating DNA in dividing cells. A University of Iowa-led study ...

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.
