This contrasts with "traditional" genetically modified organisms created by transferring existing genes from one cell type to another. Major goals of synthetic biology include re-designing genes, cells, or organisms for gene therapy ; development of minimal cells and artificial protocells ; and development of organisms based on alternative ...
Acute ecotoxicity refers to harmful effects that occur from exposure to a hazardous substance for up to 15 days. These effects are caused by the interaction of the chemical with an organism's cell membranes, often leading to cell or tissue damage or death (Peake, 2016).
Explosions of cyanobacteria known as algal blooms can produce cyanotoxins harmful to both the ecosystem and human health. These harmful algal blooms are more likely to be produced at a dangerous amount when there is an excess of nutrients, the temperature is 20 °C, there is more light, and calmer waters. [17]
All cells have a plasma membrane. In a protist, the plasma membrane is also known as the plasmalemma. Just below the plasma membrane, and in the inner fluid region, cytoplasm can be found. The pellicle structure in the protist is a thin layer of protein that helps provide the cell with some support and protection.
Degradative organisms can be engineered to increase mobility in order to access these compounds, including enhanced chemotaxis. [8] One limitation of the bioremediation process is that optimal conditions are required for proper metabolic functioning of certain microorganisms, which may be difficult to meet in an environmental setting.

“The belief that exogenous electromagnetic field radiation is not harmful to biologic cells, systems, or organisms is to ignore over a hundred years of science that has understood the direct ...
Specific concerns include mixing of genetically modified and non-genetically modified products in the food supply, [1] effects of GMOs on the environment, [2] [3] the rigor of the regulatory process, [4] [5] and consolidation of control of the food supply in companies that make and sell GMOs. [2]
When there is too much damage, apoptosis is triggered in order to protect the organism from potentially harmful cells.7 p53, also known as a tumor suppressor gene, is a major regulatory protein in the DNA damage response system which binds directly to the promoters of its target genes. p53 acts primarily at the G1 checkpoint (controlling the G1 ...
