What must happen to DNA strands before transcription can begin?
The DNA strands must separate or unwind to expose the specific gene that is going to be transcribed. This process is facilitated by enzymes that help unzip the double-stranded DNA. Once the DNA is unwound, RNA polymerase can then bind to the DNA and initiate transcription.
What process is the first step in making a protein from DNA instructions?
The first step in creating a protein is transcription - the copying of the code from DNA to mRNA. (The section of DNA must unwind before this can happen).
Does eukaryotic transcription begin before the promoter clearance?
No, Eukayotic transcription begins after promoter clearance. Promoter clearance just prepares the transcription initiation complex to begin elongation. Promoter clearance does not produce any functional gene.
What must happen to a DNA molecule before RNA polymerase can make RNA?
The DNA molecule must first unwind and separate into two strands. This process is called transcription, during which RNA polymerase can then read and transcribe one of the DNA strands to synthesize RNA.
What k must happen before meiosis can begin?
A duplication of the chromosomes is what must happen before meiosis can begin.
What must happen to DNA strands before transcription can begin?
The DNA strands must separate or unwind to expose the specific gene that is going to be transcribed. This process is facilitated by enzymes that help unzip the double-stranded DNA. Once the DNA is unwound, RNA polymerase can then bind to the DNA and initiate transcription.
What must happen before ice melts?
water must be frozen to form the ice in the first place
Which process must occur before DNA information is moved out of the nucleus by mRNA?
Transcription must occur .
What process is the first step in making a protein from DNA instructions?
The first step in creating a protein is transcription - the copying of the code from DNA to mRNA. (The section of DNA must unwind before this can happen).
What must happen before meiosis can begin?
DNA replicates and forms tetrad—APEX.
Does eukaryotic transcription begin before the promoter clearance?
No, Eukayotic transcription begins after promoter clearance. Promoter clearance just prepares the transcription initiation complex to begin elongation. Promoter clearance does not produce any functional gene.
What must happen to a DNA molcule before RNA polymerase can make RNA?
Before RNA polymerase can make RNA, the DNA molecule must be unwound and the double helix separated to expose the sequence of nucleotides that will be used to transcribe the RNA. This process is facilitated by proteins that help open the DNA molecule for transcription.
What must happen to a DNA molecule before RNA polymerase can make RNA?
The DNA molecule must first unwind and separate into two strands. This process is called transcription, during which RNA polymerase can then read and transcribe one of the DNA strands to synthesize RNA.
Why does transcription take place in the cytoplasm?
Transcription typically occurs in the nucleus of eukaryotic cells, where DNA is located, while translation takes place in the cytoplasm. However, in prokaryotic cells, transcription and translation occur simultaneously in the cytoplasm because they lack a defined nucleus. This proximity allows for a rapid response to environmental changes, as mRNA can be translated into proteins immediately after being synthesized. In eukaryotes, mRNA must first be processed and transported from the nucleus to the cytoplasm before translation can occur.
What must happen before the fertilization process can happen in pea plants?
The flowers must be open and contain ripe pollen.
What must happen to the helix of DNA for transcription to occur?
For transcription to occur, the double helix structure of DNA must unwind and separate at the promoter region of the gene being transcribed. This unwinding exposes the template strand of the DNA, allowing RNA polymerase to synthesize a complementary RNA strand by adding ribonucleotides according to the sequence of the DNA template. The DNA helix reforms after the transcription process is complete.
