What evidence suggests that a cell spends the majority of its time in interphase? A. Only a small percentage of cells in a tissue or cell culture are seen to be in mitosis at any given time. B. A large percentage of cells in a tissue or cell culture are seen to be in mitosis at any given time. C. A moderate percentage of cells in a tissue or cell culture are seen to be in mitosis at any given time. D. Mitosis is too intricate a process to last very long.

A. Only a small percentage of cells in a tissue or cell culture are seen to be in mitosis at any given time.

Explanation:

The evidence that suggests that a cell spends the majority of its time in interphase is the fact that only a small percentage of cells in a tissue or cell culture are seen to be in mitosis at any given time.

If such is not the case, a moderate to a large number of cells in tissue or cell culture should be seen in active mitosis.

Because of the longer nature of interphase when compared to mitosis, more cells are caught in the interphase stage of the cell cycle than the mitotic phase.

The correct option is A.

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
