• D)During synthesis, the translocon inner lining orients the nascent polypeptide so the more positive end faces the mitochondrial intermembrane space.
• E)After synthesis, the translocon inner lining orients the nascent polypeptide so the more positive end faces the cytosol.

Definitions:

DNA Sequences

The order of nucleotides in a strand of DNA, which determines the genetic information carried by that DNA.

Gene Targeting

A genetic technique that uses homologous recombination to change an endogenous gene's sequence to study gene function or create specific animal models for human disease.

Knock-Out Gene

A gene that has been deliberately inactivated or deleted through genetic engineering to study its function by observing the resulting phenotype.

Orthologous Genes

Homologous genes found in different species because they were inherited from a common ancestor.
