Scientists studied isolated cells at various stages of the cell cycle and found that some cells have 1.5 times more dna than the parental cell. these cells were in which phase of the cycle?

S- phase of cell cycle

Explanation:

Cell cycle is a cyclical process taken place in a cell leading to duplication of its DNA and division of cytoplasm to form two daughter cells.

The S phase of a cell cycle is an important part of the cycle which is found during interphase stage before either mitosis or meiosis.

The S phase of cell cycle is responsible for the replication of DNA. This replication DNA causes it to double before it enters mitosis or meiosis.
