In contrast to forward genetic screens, which start with a mutant phenotype and hunt for the responsible gene, reverse genetic screens take the opposite approach. They begin with a known gene and aim to identify the phenotypic effects caused by disrupting its function. This targeted approach allows ...
RNA interference, often abbreviated as RNAi, is a remarkable biological process where small RNA molecules act as cellular volume knobs, regulating gene expression by silencing specific genes. It's a natural defense mechanism found in many organisms, including plants and animals, and has become a pow...
The carrying capacity of an ecosystem is the maximum population size of a species that the ecosystem can sustain indefinitely, given the food, water, and other resources available. What are the key characteristics of carrying capacity?
- Dynamic: Carrying capacity is not a fixed number, ...
Density-dependent death rate is a phenomenon in population ecology where the death rate of a population increases as the population density increases. This occurs because as the population density increases, there is an increase in competition for resources such as food, water, and space. This leads...
