WebSep 4, 2024 · In the process of transcription, there are many enzymes involved: Helicase "unzips" the DNA double-strand Topoisomerase unwinds DNA RNA polymerase reads … WebThe correct answer is d. transcription, RNA processing, nuclear export, translation. In eukaryotic cells, protein synthesis begins with the process of transcription. During transcription, an enzyme called RNA polymerase binds to the DNA strand at a specific sequence called the promoter. The RNA polymerase then unzips the DNA and uses one …
During transcription what enzyme unzips dna
Did you know?
WebInitiation is the beginning of transcription. It occurs when the enzyme RNA polymerase binds to a region of a gene called the promoter. This signals the DNA to unwind so the enzyme can ''read'' the bases in one of the DNA strands. The enzyme is now ready to make a strand of mRNA with a complementary sequence of bases. WebJan 15, 2024 · Transcription is divided into 3 stages: initiation, elongation and termination. Types of RNA: mRNA - messenger RNA is a copy of a gene. It acts as a photocopy of a gene by having a sequence …
WebAug 23, 2024 · Generally, the transcription process transcribes DNA into mRNA, the type of RNA that carries the information that is needed in the synthesis of proteins. In … WebJul 29, 2024 · Helicase can unwind DNA by breaking the bonds between base pairs, unzipping the two strands (Image via Shutterstock) The DNA unzips like this for a couple of different reasons. For example, this happens when a cell wants to transcribe a gene into RNA. Helicase unwinds the DNA, and then an enzyme called polymerase copies it into …
WebDNA polymerase is the primary enzyme needed for replication. In transcription, a segment of DNA serves as a template for the synthesis of an RNA sequence. RNA polymerase is the primary enzyme needed for transcription. Three types of RNA are formed during transcription: mRNA, rRNA, and tRNA. Concept Review Exercises WebWhat enzyme unwinds DNA during transcription? It occurs when the enzyme RNA polymerase binds to a region of a gene called the promoter. This signals the DNA to unwind so the enzyme can ''read'' the bases in one of the DNA strands. The enzyme is now ready to make a strand of mRNA with a complementary sequence of bases.
