I'm replying in Admin mode because I'm not sure the discussion about the relationship of mrna to DNA replication is on-topic. If it is on-topic, then this portion of your reply seems a good beginning to addressing Trixie's challenge that mrna isn't involved in DNA replication:

As to whether there is transcription of the bases after the division of DNA into two strands, sense and antisense, by a protein (RNA polymerase) which uncoils the helix. The RNA polymerase is also acting on the sense strand and spining out a strand of mrna, note mrna. It is transferring information from the DNA to the ribosome so that a particular protein called helicase can be made it being absolutely vital to the replication of DNA. Helicase of course is that enzyme which separates the DNA strands for replication and along with DNA polymerase asists in the formation of a new DNA strand from free floating bases. Topoisomerase another enzyme/protein is holding tension on the yet to be unwound DNA a mechanical chore if you will.
If I understand you, you're saying that helicase is produced as a byproduct of the replication process. The question this raises is that since helicase is essential to splitting the DNA helix, at least some helicase must have been present before the splitting process began. Is your point that some of the helicase produced during replication is fed back to the process to help it continue?
If your main reason for being in this thread is to discuss the scientific nature of ID, then after your short suspension please continue, by all means. But you may want to peruse the
Forum Guidelines and take them to heart if you'd like your participation here to continue uninterrupted. Requests to clarify what you're saying should not be interpreted as opportunities to cast insults. I know it takes two to tango, and it appears possible that others may have began casting snide questions first (unraveling cross-accusations of "He did it first" takes too much time and is pointless anyway), but what often happens in such cases is that several parties find themselves temporarily suspended.
