How can you determine whether a particular gene is being transcribed in different cell types?

Select two that apply.

   (a) In situ hybridization of a labeled probe that binds the transcript can be used to visualize transcript abundance in various cell types.
   (b) If protein products of a given gene are present in different cell types, it can likely be assumed that the gene is being transcribed.
   (c) In situ hybridization of a labeled probe that binds the genomic DNA that contains the gene of interest can be used to visualize the presence of the gene.
   (d) In situ hybridization of a labeled probe that binds the transcript can be used to visualize transcript abundance in the zygote. Gene expression is unlikely to change after this cell stage.
