opines为土壤根瘤菌提供碳源或氮源,转化植物细胞合成opines供细菌利用。 1. 题目明确提到冠瘿碱(opines)被土壤根瘤菌用作唯一碳源或氮源,且转化后的植物细胞合成这些物质供细菌利用。2. 分析题干信息,核心点在于opines的功能:细菌利用其作为营养,植物被转化后生产它们。3. 质粒类型决定了opines的特异性,合成与代谢基因...
What is the composition of the cell wall of a plant cell? What is turgidity in a plant cell? How many membranes surround a chloroplast from a plant cell? Which type of cell, if any, does not have a plasma membrane? What are all the organelles in a plant cell?
What type of cell is enterocytes? Enterocytes are themajor villus epithelial cell type. They are highly specialized tall and columnar cells, with an oval nucleus located basally (Fig. 3). Is protein losing enteropathy fatal? PLE stands for Protein-Losing Enteropathy. Rather than a specific disea...
(SCD) and editing them in vitro before infusing them back into the body - a method known as cell therapy. After the success of SCD cell therapy trials,a CRISPR treatment was injected directly into human patients for the first time in 2020. This technique is known as gene therapy, and ...
In addition to your needs for food, water, and oxygen, you are both made of cells. Cells are small units of living material that make up all living things. You have billions of cells in your body, while a single bacterium is made up of one cell. Cell biology is the field of ...
[#highlight3]The light microscope cannot resolve detail finer than 0.2 micrometers, about the size of the smallest bacterium; consequently, no matter how many times its image of such a bacterium is magnified, the light microscope cannot show the details of the cell’s internal structure.[/...
Cell 141, 1241–1252 (2010). This work sheds light on a mechanism by which diet shapes the microbiota and proposes that genetic and structural analyses of Bacteroides species can infer their metabolic capacity and predict competitiveness in the presence of specific dietary polysaccharides. Article ...
The filament is a threadlike part extending outside the cell wall. It is made up of flagellin protein. The hook is a short curved structure that joins filament with the basal body. It produces repulsion like the propeller during the revolving of flagella. ...
An organism that diminishes the reproductive fitness of another organism or benefits from another organism without reciprocity. Pathogen In medicine, any organism that causes disease. In biological terms, a pathogen is a microorganism that has the inherent capacity to cross anatomical barriers and resist...
