Scientists can “edit” sequences of DNA by locating and replacing certain nucleotides. Explain how and why these edits will have consequences on the resulting trait.

Gene editing can be used to modify DNA sequences at target genes, thereby regulating proteins encoded by them

Explanation:

Gene editing refers to the methodologies used in molecular genetics to discretionally modify the DNA sequence of targeted cells. Since genes control phenotypic features by specifying the synthesis of specific proteins, these methodologies have the potential to alter specific traits. Recently, a gene-editing methodology called CRISPR-Cas9 has emerged as a versatile programmable gene-editing system which can be used to easily change the DNA both in-vitro and in vivo. This gene-editing system has been adapted from a naturally occurring genome engineering system existent in bacteria.
