What term describes DNA in G1 phase? Chromatin

What happens to the DNA in S Phase? What is DNA called? Doubled, duplicated, copied Chromatin

What happens to DNA in G2? What is DNA called at the end of this phase? DNA is coiled, condensed, and joined to its duplicate Duplicated chromosome Label the centromere. Label the sister chromatids

What happens to centrioles and everything else in the cytoplasm during G2 phase? Centrioles double Everything doubles

How would you describe sister chromatids? Joined, identical chromosomes

What is the first phase of mitosis? prophase

What happens to the nuclear envelope during prophase? dissolves

What is produced from the centrioles during prophase? Spindle Fibers

Where do spindle fibers attach to chromosomes? centromere

What happens by the end of prophase? Centrioles have moved to opposite poles Spindle fibers have attached to the centromere of the duplicated chromosomes

Name the second phase of mitosis. Metaphase What does “meta” mean? middle

Where do chromosomes align themselves during metaphase? At the equator

Name the third phase of mitosis. Anaphase What does “ana” mean? To separate

What marks the beginning of anaphase? Spindle fibers begin to separate duplicated chromosomes (sister chromatids)

What do we call the DNA being pulled towards the poles? Unduplicated chromosomes

Name the fourth phase of mitosis. Telophase What does “telo” mean? The end

What marks the beginning of telophase? Unduplicated chromosomes have reached the poles

What happens to chromosomes during telophase? Contained inside the nuclear membrane

What happens to spindle during telphase? Break down

What happens to the nuclear envelope during telophase? Two new nuclear envelopes form

How many nuclei are produced after mitosis? How many cells? 2 nuclei 1 cell

What happens during cytokinesis? Everything outside the nucleus in the cytoplasm split into two separate cells
