Answer #1

1. False: because we can say that the content of DNA in non specific or specific cell is same but the level of expression of genes are different. In same kind of cells some genes express and some genes are appeared as inactive form.

Every cell of a body of specific organism have same DNA content but each and different cell have different level of gene expression.

2. True: a define media is the artificial nutrition medium used for the growth of cell lines. The content of defined media is pre defined.

It enhances the possible genetic variations or changes in genetic composition.
