Answer:
In multicellular organisms, which begin their life with an egg or zygote cell, mitotic cell division is important in the development and maintenance of the various tissues, organs and systems that form it. The new cells caused by mitosis are genetically identical to the stem cell; This is achieved thanks to complex regulatory mechanisms that ensure the integrity of the genomic material and its proper segregation.
Explanation:
Segurine is important because it is responsible for keeping sequestered protease separase; when it is released, thanks to the degradation of segurin, the degradation of the cohesin that holds the sister chromatids together takes place. This cohesin allows chromosomal segregation, while degradation of cyclin results in the inactivation of CDK1 (cyclin dependent kinase).
When the alignment of the chromosomes does not satisfy the SAC (spindle assembly control point), the signal from non-anchored kinetocores induces protein recruitment to the control point. This signal leads to the formation of two independent complexes. The union of the two complexes will lead to the formation of a mitotic control complex. In this way, the segurin will not be marked for degradation and the separase will not be released and the chromosomes will not secrete until the requirements of the SAC are met.
The process of fusion is when two atoms combine to form a lager atom, releasing energy.
Fusion is defined as the mixing of two lighter nuclei to form one bigger and heavy nuclei. For example, two atoms of hydrogen combine together to form the helium atom. It is also termed as transmutation, as one form of element is transformed into another.
An atom is the smallest unit of any substance. It cannot be further broken down into simpler units. The composition of an atom includes various subatomic particles. These are: a nucleus surrounded by various electrons. Nucleus itself is made up of two subatomic particles: protons and neutrons.
