Explain the general structure of DNA. Deoxyribonucleic Acid (DNA) DNA is a very long, thin molecule. It is one of two types of biological macromolecules called nucleic acids. It is composed of smaller subunit molecules called nucleotides that have a three-part structure that includes a sugar (...
Describe the structure and function of DNA. Describe how the structure of DNA (double helix and base pair rule) is correlated with its role as the molecular basis of inheritance and uniqueness. Describe the structure of DNA and its correlation to its role as the molec...
In this activity, students are asked to use their understanding of noncovalent interactions to explain (a) why the boiling point differs for two pure substances (chemistry phenomenon) and (b) why temperature and base pair composition affects the stability of DNA (biological phenomenon). The ...
Explain the function of the cell membrane in a cell structure. Describe an organelle and its functions. Describe the structure and function of each of the eukaryotic organelles. Explain the function of endoplasmic reticulum in a cell. Describe the structure and functions of...
Previous studies focusing on the age disparity in COVID-19 severity have suggested that younger individuals mount a more robust innate immune response in the nasal mucosa after infection with SARS-CoV-2. However, it is unclear if this reflects increased
The key is in the disorder Studying the structure of pseudogapped superconductors at microscopic level showed that these materials are strongly disordered. This means that their atoms are not arranged in a perfect crystal lattice, or the structure of this lattice is strongly impaired. Examples of ...
Our results collectively showed the molecular signature of an endothelial/epithelial-mesenchymal (EndMT/EMT) transition-like process, associated with instability of intimal cell junctions and activation of RHOA pathway in the intima and media layers of ascending aorta in BAV patients. We propose that ...
Several years ago, Rajapakse approached him during a visit to U-M, where Smale earned his undergraduate and graduate degrees. They began exploring how to study the human genome—the set of genes in an organisms DNA—as a dynamical system. ...
A virus, the simplest physical object in biology, consists of a protein shell called the capsid, which protects its nucleic acid genome—RNA or DNA. The capsid can be cylindrical or conical in shape, but more commonly it assumes an icosahedral structure, like a soccer ball. ...
