Chromosome behaviour in mitosis — practice question

The diagram illustrates a human cell $(2n = 46)$ at the close of prophase of mitosis (cell 1) and daughter cells immediately after telophase (cells 2 and 3). How many DNA molecules are present in the nucleus of cell 1 and cell 2?

  • Acell 1: $46$, cell 2: $23$
  • Bcell 1: $46$, cell 2: $46$
  • Ccell 1: $92$, cell 2: $23$
  • Dcell 1: $92$, cell 2: $46$
