what is the nuclear content of the daughter cell in mitosis and in amitosis?!?

Answer 1

Each daughter cell will have the same nuclear content as the mother cell, irrespective of whether it undergoes mitotic or amitotic division.When a cell prepares for division its DNA content is already duplicated in S phase of interphase.
The difference between the mitotic and amitotic division lies in the existence/nonexistence of the mitotic apparatus. In amitotic division there is no mitotic apparatus. Otherwise both are equational.

Answer 2

Well, DNA organized in condensed chromosomes which rapidly decondense in loose chromatine filaments at the end of telophase. At the beginning of mitosis each chromosome consists of 2 sister chromatides, which become separated at anaphase, so that at the end of mitosis (telophase), each chromosome will have a 'one-chromatide' structure, and the daughter cell will contain a 2N amount of DNA.
