Cell Cycle and Division
מהו מחזור התא?
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 ...
דנ״א גנומי בפרוקריוטים
The genome of most prokaryotic organisms consists of double-stranded DNA organized into one circular chromosome in a region of cytoplasm called the ...
ביקוע בינארי
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 ...
דנ״א גנומי באאוקריוטים
Eukaryotes have large genomes compared to prokaryotes. To fit their genomes into a cell, eukaryotic DNA is packaged extraordinarily tightly inside the ...
אינטרפאזה
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 ...
מיטוזיס וציטוקנזיס
In eukaryotes, the cell division cycle is divided into distinct, coordinated cellular processes that include cell growth, DNA replication/chromosome ...
מוקלות בקרה חיובית
To consistently produce healthy cells, the cell cycle—the process that generates daughter cells—must be precisely regulated.
Internal ...
מולקולות בקרה שלילית
Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a ...
סרטן
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and ...
