Which statement is accurate regarding transgenic techniques?

Pronuclear injection is indeed less specific than gene-targeted methods. This technique involves introducing a foreign gene into a fertilized egg by injecting it into one of the pronuclei. While it has been widely used for creating transgenic organisms, the integration of the transgene can occur randomly within the genome, which may lead to unpredictable expression patterns and potential disruptions of endogenous genes.

In contrast, gene-targeted methods, such as homologous recombination, allow for more precise modifications by replacing or integrating genes at specific loci within the genome. This specificity can enhance the accuracy of the genetic modification and beneficially influence the study of gene function and disease modeling.

Thus, C accurately reflects the difference in specificity between these two techniques and underscores the broad celebration of gene-targeted methods for their precision compared to pronuclear injection.
