Study now. RNA polymerase attaches to the DNA at a specific area called the promoter region. This signals the DNA to unwind so the enzyme can ''read'' the bases in one of the DNA strands. 1 See answer Add answer + 5 pts Suntron3000 is waiting for your help. Reference: 1. Thus, DNA replication requires an RNA primer to initiate strand formation. To initiate transcription, an RNA polymerase enzyme binds to a promoter region on DNA, and the DNA double helix unwinds into a template strand and non-coding strand. This signals the DNA to unwind so the enzyme can ''read'' the bases in one of the DNA strands. prokaryotes, eurkaryotes, both or neither: translation of the mRNA begins before transcription is finished. RNA polymerase is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, duyring the process of transcription. 8. introns are portions of RNA that are cut out and discarded. 13.2 Ribosomes and Protein Synthesis Lesson Objectives Identify the genetic code and explain how it is read. This signals the DNA to unwind so the enzyme can ''read'' the bases in one of the DNA strands. 28. RNA polymerase binds to the beginning of a gene on a region of DNA called a promoter. A 7-methyl guanosine nucleic acid is added to the 5-end (known as a 5 cap) of the pre-mRNA as it emerges from RNA polymerase II (Pol II). RNA polymerase binds to regions of DNA called promoters , which are "start" signals for transcription. That mRNA is then translated into proteins. The sigma ( factor) subunit of RNA polymerase binds specifically to sequences in both the - 35 and - 10 promoter regions, indicating the importance of these regions in promoter function. What does RNA polymerase do? Elongation is the addition of nucleotides to the mRNA strand . When a repressor protein binds to the silencer region of DNA, RNA polymerase is prevented from transcribing the DNA sequence into RNA. ; RNA polymerase binds to DNA at a sequence called a promoter during the initiation of transcription.

Using the enzyme helicase, RNAP locally opens the double-stranded DNA so that one strand of the exposed nucleotides can be used as a template for the synthesis of RNA, a process called transcription. During transcription, RNA polymerase makes a copy of a gene from the DNA to mRNA. C)In eukaryotes, transcription takes place in the cytoplasm and requires many enzymes. Figure 2.3. . RNA polymerase is a multi-unit enzyme that synthesis RNA molecules from the DNA molecule during the process of transcription. The transcription starts with binding of the enzyme RNA polymerase to a promoter sequence on the DNA, a regulatory region that dictates where the transcription should start. The promoter region has no role in translation. . The first step in transcription is initiation, when the RNA pol binds to the DNA upstream (5) of the gene at a specialized sequence called a promoter (Figure 2a). A RNA polymerase (RNAP), or ribonucleic acid polymerase, is a multi subunit enzyme that catalyzes the process of transcription where an RNA polymer is synthesized from a DNA template. 1. Elongation Certain enzymes called transcription factors unwind the DNA strand and allow RNA polymerase to transcribe only a single strand of DNA into a single . ; RNA polymerase synthesizes RNA, using the antisense strand of the DNA as template by adding complementary RNA nucleotides to the 3 end of the growing strand. It is a 7 bp long region located 20 bp upstream to the start point. Binding of RNA polymerase to DNA duplex: On a signal from the cytoplasm, the histone coat protecting the DNA double helix at the region of the gene to be transcribed is removed, thereby exposing the polynucleotide sequences of the specific region of DNA. RNA polymerase. To begin transcribing a gene, RNA polymerase binds to the DNA of the gene at a region called the promoter.Basically, the promoter tells the polymerase where to "sit down" on the DNA and begin transcribing.It contains recognition sites for RNA polymerase or its helper proteins to bind to. 2013-05-03 22:10:11. Extrons .binds tightly to a region of DNA located thousands of base pairs away from the DNA to be transcribed. It occurs when the enzyme RNA polymerase binds to a region of a gene called the promoter. These sequences alone are sufficient for transcription initiation to occur, but promoters with additional sequences in the region from -180 to -105 upstream of the initiation site will further enhance initiation. .
