Top: Both X-chromosome territories are detected by FISH. Shown is a single optical section made with a confocal microscope. Bottom: Same nucleus stained with DAPI and recorded with a CCD camera. The Barr body is indicated by the arrow, it identifies the inactive X (Xi). Left: DAPI stained female human fibroblast with Barr body (arrow). Right: histone macroH2A1 staining. Arrow points to sex chromatin in DAPI-stained cell nucleus, and to the corresponding sex chromatin site in the histone macroH2A1-staining.
Usage Guidelines. Up to 16 security levels can be configured using Cisco IOS software. If such levels are configured on a system, using this command with the privilege-level option allows you to exit to a lower security level. If a level is not specified, the user will exit to the user EXEC mode, which is the default.
We will be going with three Cisco 2960-S switches. The main components that you will need are: switches, stack modules and stack cables.

The steps to stack Ciscoâs 2960-S switches are generally the same so I wonât go into too much detail, but I wanted to shed some light on it just to provide some coverage for anyone that is looking to do this on their network.
