What event immediately precedes anaphase?

The end of metaphase gets anaphase to start.


Why is it necessary for the organelles to double during interphase?

Interphase precedes prophase and metaphase. Metapase is associated with cell growth and division. When cells divide, there should be enough organelles and genetic material to support both the daughter cells formed. Therefore, it is essential the organelles double so as to divide equally into the daughter cells.


Anatomical term for forehead?

Forehead means, literally, the front of your head. Fore means "front", so where the word fore precedes another word, chances are it means in the front of, e.g. foreground, foresight, forerunner.


How does prophase you differ from prophase II?

At the beginning of telophase I, each half of the cell has a complete haploid set of chromosomes, but each chromosome is still composed of two sister chromatids. Cytokinesis usually occurs simultaneously with telophase I, forming two haploid daughter cells. No chromosome replication occurs between the end of meiosis I and the beginning of meiosis II, as the chromosomes are already replicated. In telophase II, the nuclei form and the chromosomes begin decondensing. The meiotic division of one parent cell produces four daughter cells, each with a haploid set of (unreplicated) chromosomes.


What stage of the cell cycle is a cell's DNA copied?

The stage in the cell cycle where DNA is replicated is actually in interphase, before the nuclear membrane dissolves in prophase. * The DNA is replicated at mid-interphase (in the S phase), between the two growth phases (G1 and G2). So replication precedes division by several hours in a typical cell.
