The five phases of mitosis and cell division tightly ... Prometaphase is an extremely dynamic part of the cell cycle. Microtubules rapidly assemble and disassemble as they grow out of the ...

This sequential expression followed the phases of the traditional cell cycle: G0/G1 (the cell grows larger), S (the cell replicates its DNA), and G2/M (the cell prepares for division and then splits).

I talked to two ob-gyns and two mental health experts to find out what happens to menstruating people’s bodies and minds ...

When looking at cells with a microscope, the length of different stages of the cell cycle can be estimated using the formula: \(\text{Length of time in phase}=\) \(\frac{\text{observed number of ...

About 100 cells divide every second in our body. A key protein in cell division is a protein kinase termed Plk1, because it ...

A life cycle is the series of stages something passes through during its lifetime. We also use the term for things that are not living, like cell phones. The life cycle for anything you buy includes ...

Germinal centers are high-speed evolution machines. Tiny clusters in the lymph nodes, germinal centers refine antibodies through mutation and expansion until they produce high-affinity B cells adapted ...

It is these events that determine whether the cell cycle will go forward or remain stalled between stages. Here we focus on the transformation assay, which scientists first used to identify ...

The menstrual cycle has four phases: menstrual, follicular, ovulation, and luteal. The main purpose of the menstrual cycle is to produce an egg for potential fertilization by sperm. Stress ...

Before a cell can divide, it must grow and make copies of all the organelles such as mitochondria and ribosomes. The cell must also replicate the chromosomes in the nucleus, then it can divide by ...
