When DNA replication occurs, the DNA strand is being unwound, causing the DNA to be overwound tightly past the replication fork.
For example, If you have ever wrapped two strings around each other and then tried to pull part the middle of the string while holding the ends tight, the rest of the string past the place you're pulling the string apart becomes very tight and strained.
Topoisomerase is an enzyme that binds to the DNA and helps release some of that strain by unwinding the DNA past the replication fork.

Close suction drains play very crucial in surgical wound healing. It is important that the wound suction drain works properly because the proper healing of the wound depend on it. If the wound suction drain do not work properly, it will be difficult to obtain accurate recording of the volume and the contents of the drainage that is coming out from the wound. Thus, it will be difficult to monitor for excessive bleeding, infections and things like that which may prevent proper healing.
