Change of the physical state of matter from gas phase into liquid phase; reverse of evaporation

concept

HeLa cell in prometaphase. The chromatin is stained red and the microtubules forming the spindle stained green. The chromatin has condensed but there is not yet complete attachment of the chromosomes to the spindle.

Human cell in metaphase

Nucleus in prometaphase. The chromosomes are stained green. The chromatin has condensed but there is not yet complete attachment of the chromosomes to the spindle (not visible in the image).

Human chromosomes in early anaphase. At this stage the chromosomes have started to separate from each other and move towards opposite poles of the cell. The chromatin appears grey and the kinetochores are pink.

Human cells showing the stages of cell division starting with interphase at the top. Progressing down, the stages shown are: prophase, metaphase (chromosomes all attached and aligned), anaphase (chromosome separation)and telophase (formation of midbody and cells begin to flatten).

Human cells showing the stages of cell division

Human cell in telophase

Human chromosomes in late anaphase. At this stage the chromosomes have started to separate from each other and move towards opposite poles of the cell.

Human cell in anaphase

Nucleus in early prophase

Human chromosomes in early anaphase. At this stage the chromosomes have started to separate from each other and move towardds opposite poles of the cell.

Human chromosomes in metaphase. The chromatin is stained red and the "glue" that holds the two chromatids together is highlighted in yellow. This glue is a proteinaceous complex called cohesin. Once all the chromosomes are attached to the spindle, the cohesin complex breaks down, allowing the two chromatids to separate and move to opposite poles of the cell.

We're experiencing some technical problems in the library today. 

If you’re visiting us, you won’t be able to print or use our PCs or laptops. If you want to sign-up for a free library membership, we’ll give you a temporary card for today and complete your membership next time you visit.

You can access items from the collection as usual and our team is on hand to help. Thank you for your patience while we resolve these issues. 

We're running paid user research studies to improve Wellcome Collection online
