The relatively short lifespans of mice means it’s possible to determine the effects of a gene knockout from birth right through old age. Knockout (KO) mice contain a gene inserted or deleted using embryonic stem cells or more recently, CRISPR. Provides important clues about what that gene normally does because human share many genes with mice. Disadvantages: Incomplete loss of gene function due to remaining functional mRNA. Soon people found ways to make more precise changes to the mouse genome, including changes that could disrupt the function of a single gene to create knockout mice. Not only are they difficult, costly, and time-consuming, many people feel it’s unethical to use animals in laboratory research. Thanks to animal models, research on genetics has advanced further than we ever anticipated. Against those disadvantages are several important advantages to using knockout mice in behavioral research: (1) disabling a gene is often a very precise and "clean" ablation, (2) the effects of the gene product can be abolished without the side-effects of drugs, … Facebook While knockout mice technology represents a valuable research tool, some important limitations exist. 2018 May 8;9:906. doi: 10.3389/fmicb.2018.00906. some advantages, disadvantages and ethical considerations spacecraft (Dubinin et al.
