細胞周期と分裂
細胞周期とは？
The cell cycle refers to the sequence of events occurring throughout a typical cell’s life. In eukaryotic cells, the somatic cell cycle has two ...
原核生物のゲノムDNA
The genome of most prokaryotic organisms consists of double-stranded DNA organized into one circular chromosome in a region of cytoplasm called the ...
二体分裂
Fission is the division of a single entity into two or more parts, which regenerate into separate entities that resemble the original. Organisms in the ...
真核生物のゲノムDNA
Eukaryotes have large genomes compared to prokaryotes. To fit their genomes into a cell, eukaryotic DNA is packaged extraordinarily tightly inside the ...
インターフェーズ
The cell cycle occurs over approximately 24 hours (in a typical human cell) and in two distinct stages: interphase, which includes three phases of the ...
有糸分裂と細胞質分裂
In eukaryotes, the cell division cycle is divided into distinct, coordinated cellular processes that include cell growth, DNA replication/chromosome ...
正の制御分子
To consistently produce healthy cells, the cell cycle—the process that generates daughter cells—must be precisely regulated.
Internal ...
負の制御分子
Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a ...
がん
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and ...
