Gene order can be inferred from gene expression patterns since
A)proteins that act first in a pathway are ususally expressed before proteins that act later in a pathway.
B)mRNA for proteins in a pathway are produced at the same time but then are translated only when the proteins are needed.
C)proteins in a pathway are produced at the same time but the proteins that are not needed are degraded.
D)mRNAs for proteins in a pathway are produced at the same time and thost that are not needed are destabilized by miRNAs.

Proteins that act first in a pathway need to be present before proteins that act later in the pathway. Therefore, their expression usually occurs first, which can be inferred from gene expression patterns.
