Question

1. at first, interphase was called the “resting phase” of the cell cycle. what did scientists learn about interphase as new techniques and tools to study cells were developed?

Explanation:

With new techniques like electron - microscopy and biochemical assays, scientists found that interphase is a highly active phase. During this phase, the cell grows, replicates its DNA in the S - phase (synthesis phase), and synthesizes proteins and organelles needed for cell division. It is a crucial preparatory stage for mitosis or meiosis.

Answer:

Scientists learned that interphase is a highly active phase where the cell grows, replicates DNA, and synthesizes proteins and organelles for cell division.
