When a gene is to be expressed, the base sequence of DNA is copied or transcribed into mRNA (messenger RNA). This process takes place in the nucleus and occurs in a series of stages.

1.RNA polymerase moves along the DNA unwinding the strand.

2.Hydrogen bonds between base pairs break which allows the unzipping of the double helix.

Hope that answer fits your question.

You should wait at least half an hour before trailing the deer. You should try to watch carefully and see which way it goes. Chasing a wounded animal yields meat that tastes gamey, so try not to chase. When you do trail, follow the blood trail. Listen carefully while you wait and try to hear where the deer is or if it goes down.

It is the process of bone development from fibrous membranes. It is involved in the formation of the flat bones of the skull, mandible and the clavicle.
