Does replication occur before transcription
WebApr 10, 2024 · DNA replication is the process by which the genome’s DNA is copied in cells. Before a cell divides, it must first copy (or replicate) its entire genome so that each resulting daughter cell ends up with its own … WebIn a prokaryotic cell, by the time transcription ends, the transcript would already have been used to begin making copies of the encoded protein because the processes of transcription and translation can occur at the same time since both occur in the cytoplasm ( Figure 3 ).

WebThere's one more difference I want to talk about in how translation happens in prokaryotes and eukaryotes and that is what the first amino acid in the polypeptide chain will be. So …
WebJul 30, 2024 · A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time. Mutations can also occur as the result of exposure to … 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.
WebWhich process MUST occur before mitosis and meiosis can occur? A) DNA translation B) DNA replication C) DNA conjugation D) DNA transcription ... 16. in which part of the cell does transcription occur how about translation. Answer: ... 27. ACTIVITY 2: arrange the following events for replication, translation,and transcription Answer: REPLICATION ... 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.
