03. Interphase

How much of the cell cycle is interphase?

90%

What are the phases of interphase?

Growth 1, synthesis, growth 2

What happens in growth 1?

Cell size increases and organelles replicate

What happens in synthesis?

DNA synthesis

What happens in growth 2?

Centrioles replicate

How do you know a cell is in interphase?

You can see a nucleus

What happens in interphase?

Replication of DNA + organelles which have their own DNA (mito and chloro), Making new organelles -> do not say replicate, Synthesis of ribosomal material, ATP and proteins, Increase in cell size -> do not say growth

What has not happened in interphase yet?

chromosomes have not condensed and chromatids not visible
