The study of the cell cycle focuses on mechanisms that regulate the timing and frequency of DNA duplication and cell division. As a biological concept, the cell cycle is defined as the period ...

Embryonic stem cells are pluripotent. This means that all of the genes in an embryonic stem cell can be expressed so they can give rise to all types of cell. They are important for growth.

Though the genetic code of a human being is contained within 46 ... Meiosis, a type of cell division specific to reproduction, avoids this by halving the number of chromosomes in a cell.

A human cell contains 46 chromosomes ... a fertilized egg would contain 92 chromosomes and be untenable. Meiosis, a type of cell division specific to reproduction, avoids this by halving the ...

Without cell division, long-term tissue survival would ... For instance, the cells that make up human epithelial tissue attach to one another through several types of adhesive junctions.

Cell division is key for life. Every organism—from the smallest yeast to complex human beings—depends upon the constant reproduction of individual cells. In this process, various mechanisms ...

In a development that could challenge the boundaries of technology and biology, an Australian startup has unveiled the ...

The improved resolution will promote advanced cell analysis in the human body, especially in cases of incorrect cell division such as in the context of cancer. The research is published in Nucleic ...
