1. What is the cell membrane? 2. What does it contain? How does it function? 3. Is it prokaryotes or eukaryotes? What are the structures found in both eukaryotes and prokaryotes? What are the main parts of a eukaryotic cell? What type of organelles do prokaryotes ...
The theory of topological BOs in 3D HOTIs We consider a 3D lattice model consisting of cubic stacked unit cells, with each unit cell consisting of 8 lattice sites, as shown in Fig. 1a, b. These lattice sites are distributed in space at equal intervals δ. As a result, the lattice cons...
Plant growth results from both the cell proliferation and growth of the cell size. The cellulose wall of plant cells restraints the cell growth, but cell wall in plants expands under the action of cell loosening enzymes, such as expansins, which disrupt hydrogen bonds between cellulose microfibri...
We identified 3 previously unreported structural phenomena in the cell ontogeny of O. oeni sampled in northern China. We show that budding and binary fission (BBF) occur simultaneously in the growth process; that a novel ‘pomegranate-shaped structure’ (PSS) occurs mainly in the stationary and ...
A complete theory of ligand discrimination would be able to describe the types of motions and energetic connections that define selectivity for a particular ligand within a particular system. In molecular simulations, binding calculations usually focus on a circumscribed region of the protein near the ...
Answer to: Briefly describe the three types of chemical inhibition of enzyme activity. Which of these are used in the cell to control enzymatic...
Unlike regular elastic materials, when auxetic materials are compressed, they become thinner in the direction perpendicular to the applied force. Despite their outstanding mechanical properties, a systematic design of new and controlled auxetics remains underdeveloped. Here we establish a unified framework...
Chiral LC mixtures were then introduced into the cell by capillary forces. To achieve electric control of LC background fields and solitons, the electrodes of the LC cells were connected to a function generator (DS345; Stanford Research Systems) operating at 1 kHz carrier frequency with ...
