Capitolo 10
Ciclo e divisione cellulare
Cos'è il ciclo cellulare
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 ...
DNA genomico nei procarioti
The genome of most prokaryotic organisms consists of double-stranded DNA organized into one circular chromosome in a region of cytoplasm called the ...
Fissione binaria
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 ...
DNA genomico negli eucarioti
Eukaryotes have large genomes compared to prokaryotes. To fit their genomes into a cell, eukaryotic DNA is packaged extraordinarily tightly inside the ...
Interfase
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 ...
Mitosi e citochinesi
In eukaryotes, the cell division cycle is divided into distinct, coordinated cellular processes that include cell growth, DNA replication/chromosome ...
Molecole regolatrici positive
To consistently produce healthy cells, the cell cycle—the process that generates daughter cells—must be precisely regulated.
Internal ...
Molecole regolatrici negative
Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a ...
Cancro
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and ...
