The answer may be, Replication, but I am unsure.
The enzyme that breaks down H2O2 is called catalase.
<span>My pea plant has an unknown genotype for flowers, whether it has two dominant traits for white flowers (WW) or one dominant and one recessive (Ww) leading to white flowers; therefore I am doing a testcross in order to determine the genotype of my pea plant. The best plant to do this with is one that has a phenotype of purple flowers (ww) - that is, it is homozygous for the recessive trait.
If I use a homozygous recessive plant, I know exactly what its genotype is. I don't have to worry about whether it's got one or two dominant alleles; I know that at least half of my alleles are going to be the recessive w.
This makes identifying the offspring's genotype very simple. If I find that the offspring have at least some purple flowers among them, I know that my original plant had to be Ww; that is it had to have one dominant and one recessive allele for the flower color gene. If, however, all of the offspring are white flowers, I know that my original pea plant had both dominant alleles (WW).</span>

FULL ANSWER<span>The five main phases of mitosis are prophase, prometaphase, metaphase, anaphase and telophase. Some mitosis timelines include interphase, where the cell begins preparing to undergo mitosis. Prophase is the official start of mitosis, and during this step duplicated DNA strands condense into a more compact form and take on the traditional X shape of chromosomes.During prometaphase, the membrane around the cell's nucleus dissolves so that the chromosomes can move into place at the center of the cell. Spindle fibers align the chromosomes in the center of the nucleus during metaphase. This phase is essential to the health of the daughter cells, since it lines the chromosomes up evenly so they can be easily split in the next phase.Anaphase is the phase where two different cells start truly forming. The chromosomes are pulled apart, and half of each chromosome is pulled to separate ends of the cell, creating two bundles of chromosomes.In telophase, these bundles of chromosomes are enclosed in a new nuclear membrane. Once safely enclosed, the chromosomes break up again and lose their compact look. Finally, in cytokinesis the two sides break apart to create two new identical daughter cells.</span>
