DNA STRUCTURE – Review…… DNA is made of monomers called nucleotides. Nucleotides consists of 5 carbon sugar Phosphate group Nitrogenous base (A,T,C,G) Backbone- made of covalent bonds between bonds between the phosphate and sugar “Rungs of Ladder” – made of pairs of nitrogenous bases. ...

DNA — a new twist on life The determination in 1953 of the structure of deoxyribonucleic acid (DNA), with its two entwined helices and paired organic bases, was a tour de force in X-ray crystallography. But more significantly, it also opened the way for a deeper understanding of perhaps ...
Molecular Biology is the field of biology that studies the composition, structure and interactions of cellular molecules such as nucleic acids and proteins that carry out the biological processes essential for the cells functions and maintenance. ...

An innovative technique called HORNET uses atomic force microscopy and a machine-learning architecture called a deep neural network to recapitulate the 3D structures of individual RNA molecules. This method enables the study of the structure and dynamics of RNAs that adopt flexible and variable conforma...
