Conditional gene knockout is a technique used to eliminate a specific gene in a certain tissue, such as the liver. [1] [2] This technique is useful to study the role of individual genes in living organisms. It differs from traditional gene knockout because it targets specific genes at specific times rather than being deleted from beginning of life.
The International Knockout Mouse Consortium (IKMC) is a scientific endeavour to produce a collection of mouse embryonic stem cell lines that together lack every gene in the genome, and then to distribute the cells to scientific researchers to create knockout mice to study.
Bobcat urine repels moles, mice, voles and other rodents. Wolf urine is used to repel moose. Used cat litter is also effective. Domestic dogs can be repelled by vinegar. [4] Other repellents are not chemical. A simple electrified or barbed-wire fence can mechanically repel livestock or predator animals. Some electrical repellent systems have ...
Oil of lemon eucalyptus is a long-lasting, effective way to repel mosquitoes and ticks, according to the CDC. A half-ounce bottle of lemon eucalyptus oil costs less than $7, and only a small ...

A complete gene knockout permanently inactivates the gene, while a conditional gene knockout allows for the gene to be turned off and on at specific times or in specific tissues. Conditional knockouts are particularly useful for studying developmental processes and for understanding the role of a gene in specific cell types or tissues.
