Question

1. short pieces of rna called micrornas (mirnas) play a role in cellular differentiation by acting in synchrony with protein transcription factors. together, the mirnas and protein transcription factors – prevent proteins that regulate gene expression within the cell from affecting the cell destroy proteins that regulate gene expression within the cell produce proteins that regulate gene expression within the cell capture proteins outside the cell to regulate gene expression within the cell clear all

Explanation:

miRNAs and protein transcription factors work together to regulate gene - expression during cellular differentiation. They do not prevent, destroy, or capture proteins as described in the incorrect options. They are involved in producing or modulating the production of proteins that regulate gene expression.

Answer:

produce proteins that regulate gene expression within the cell.
