Answer:

Here are the events of X-chromosome inactivation in the correct sequence:

1) The XIST gene on one of the X chromosomes is activated and produces XIST RNA.

2) The XIST RNA coats the X chromosome on which it was produced and recruits other proteins.

3) The proteins recruited by XIST RNA modify the chromatin structure of the X chromosome, making it more compact and inaccessible to transcription factors.

4) Transcription of most genes on the coated X chromosome is turned off.

5) The inactivated X chromosome (also known as a Barr body) is physically separated from the active X chromosome and remains condensed throughout the cell cycle.
