Summary
Genomically minimal cells like JCVI-syn3A use many genes for cell division. Studying their physical mechanics, like surface-area-to-volume ratio and membrane curvature, helps understand gene function in synthetic biology.
Area of Science:
- Synthetic biology
- Microbiology
- Genomics
Background:
- Genomically minimal cells, such as JCVI-syn3.0 and JCVI-syn3A, provide a simplified model for studying genotype-phenotype relationships.
- Cell division in JCVI-syn3A is a complex process influenced by numerous genes, some with unknown functions.
Purpose of the Study:
- To review current knowledge on genes in JCVI-syn3A that influence physical parameters of cell division.
- To explore how physical descriptions of cellular mechanics can elucidate gene function in minimal cells.
Main Methods:
- Literature review of genes in JCVI-syn3A.
- Analysis of genes affecting surface-area-to-volume ratio and membrane curvature.
- Focus on physical parameters relevant to cell division.
Main Results:
- Identified genes in JCVI-syn3A contributing to surface-area-to-volume ratio and membrane curvature.
- Highlighted the importance of physical cellular mechanics in understanding gene function.
Conclusions:
- A physical perspective on JCVI-syn3A aids in attributing gene functions and understanding conserved bacterial processes.
- This approach can inform whole-cell models and the engineering of synthetic cells.

6.6K
In eukaryotes, the cell division cycle is divided into distinct, coordinated cellular processes that include cell growth, DNA replication/chromosome duplication, chromosome distribution to daughter cells, and finally, cell division. The cell cycle is tightly regulated by its regulatory systems as well as extracellular signals that affect cell proliferation.
The processes of the cell cycle occur over approximately 24 hours (in typical human cells) and in two major distinguishable stages. The...

02:13Determining the Plane of Cell Division
3.4K
Positioning the cell division plane is a critical step during development and cell differentiation, particularly during mitosis when the plane is essential for determining the size of the two daughter cells. The cell division plane is perpendicular to the plane of chromosome segregation, but different types of organisms have different cell division mechanisms to suit their morphology and function.

01:20Binary Fission
56.6K
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 Archaea and Bacteria domains reproduce using binary fission, in which a parent cell splits into two parts that can each grow to the size of the original parent cell. This asexual method of reproduction produces cells that are all genetically identical.

02:33Distribution of Cytoplasmic Content
4.2K
Cytokinesis segregates a cell’s chromosomes and organelles into its daughter cells. Organelles divide and grow prior to cell division but cannot be synthesized de novo; therefore, cells must receive at least one copy of each organelle to survive. Currently, many of the details of how the organelles are distributed are not yet fully elucidated.

02:15Condensins
3.6K
Condensins are large protein complexes that use ATP to fuel the assembly of chromosomes during mitosis. They transform the tangled, shapeless mass of post-interphase DNA into individualized chromosomes by compacting, organizing, and segregating chromosomal DNA.
The plant and animal cells contain two types of condensin complexes—condensin I and condensin II. Both complexes have five subunits: two SMC (Structural Maintenance of Chromosomes) subunits, a kleisin subunit, and two HEAT-repeat...

02:36Cells Coordinate Growth and Proliferation
4.6K
Cell size is a significant factor impacting cellular design, function, and fitness. There exists some internal coordination by which cells double their masses before division, thus, achieving homeostasis. Coordination between cell growth and proliferation depends on the checkpoints in between cell cycle phases. Loss of coordination or failure in the checkpoint mechanism can drive the cell to uncontrolled growth and loss of cellular function. Like dividing cells that coordinate cellular growth,...
