What are the lin-4 and lin-14 genes of C. elegans?

#Unit 5. Developmental Biology
  1. lin-4 encodes a miRNA that represses lin-14 translation, which in turn regulates the timing of larval development
  2. lin-4 and lin-14 are genes that are named for their control of the first division, and hence the lineage of the AB and P1 cells
  3. lin-4 and lin-14 are C. elegans versions of the HOX genes
  4. lin-4 and lin-14 both encode miRNAs that serve as cell-cell signaling molecules in C. elegans

#Unit 12. Applied Biology

Glyphosate resistance in plants can be generated by expressing in them transgenes that serve one of the following three purposes: 
(1) Overproduction of EPSPS enzyme 
(2) Encode an EPSPS enzyme that is tolerant to glyphosate
(3) Produce an enzyme that inactivates glyphosate
(4) Use a combination of the strategies (2) and (3)
Which of the above strategies can be used to make plants glyphosate resistant?
