Chimera

Definition

In biology, a chimera refers to an organism that contains cells from two or more genetically distinct individuals. This can happen naturally, such as through the fusion of embryos, or artificially, such as in genetic engineering and transplantation. The concept of chimera plays a significant role in structural bioinformatics and protein structure prediction by allowing scientists to create and analyze hybrid proteins or structures that may exhibit novel properties.
