Does replication occur before transcription

WebMar 1, 2024 · The first step of transcription is called pre-initiation. RNA polymerase and cofactors (general transcription factors) bind to DNA and unwind it, creating an initiation bubble. It's similar in appearance to what you get when you unwind strands of multi-ply yarn. This space grants RNA polymerase access to a single strand of the DNA molecule. WebMar 1, 2024 · Also, if replication occurs just before mitosis, then you get unequal separation of genetic material. Thus it is important to keep replication and mitosis separated by the G phases to prepare the cells.

WebReplication occurs in the nucleus. Transcription: involves complementary base pairing to DNA, but transcription reads a portion of the DNA responsible for one protein or polypeptide. This results in pre mRNA consisting of portions, eons & introns. Enzymes cut out the introns and attach exons together to form mature mRNA. Viral replication is the formation of biological viruses during the infection process in the target host cells. Viruses must first get into the cell before viral replication can occur. Through the generation of abundant copies of its genome and packaging these copies, the virus continues infecting new hosts. Replication between viruses is greatly varied and depends on the type of genes involved i…
