Ciclo e Divisão Celular
O que é o Ciclo Celular?
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 Genômico em Procariontes
The genome of most prokaryotic organisms consists of double-stranded DNA organized into one circular chromosome in a region of cytoplasm called the ...
Fissão Binária
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 Genômico em Eucariontes
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 ...
Mitose e Citocinese
In eukaryotes, the cell division cycle is divided into distinct, coordinated cellular processes that include cell growth, DNA replication/chromosome ...
Moléculas Reguladoras Positivas
To consistently produce healthy cells, the cell cycle—the process that generates daughter cells—must be precisely regulated.
Internal ...
Moléculas Reguladoras Negativas
Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a ...
Câncer
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and ...
