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.

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 for a new moon to occur?
For a new moon to occur the moon must be between earth and the sun
What must happen for specification to occur?
A population must be isolated in some way
What two processes must occur to get from a gene to a protein?
The process by which a gene is read is through transcription and occurs through the activity of an enzyme called RNA polymerase II in the nucleus. This results in the formation of molecule called messenger RNA (mRNA). mRNA is then translated into a string of amino acids or protein by transfer RNA (tRNA) on ribosomes outside the nucleus in the cytoplasm.
What thing have to happen for photosynthesis to occur?
For photosynthesis to occur, three main things have to happen: 1) sunlight must be available to provide energy, 2) carbon dioxide must be present as a source of carbon, and 3) water must be available as an electron donor. These three factors are essential for the process of photosynthesis to take place in plants.
What must happen to the DNA before transcription can take place?
Before transcription can take place, the DNA in the cell nucleus must be unwound and separated into two strands by enzymes. This process exposes the genetic information that will be transcribed into mRNA.
What must occur before replication can?
the double helix must unwind
Which process must occur before DNA information is moved out of the nucleus by mRNA?
Transcription must occur .
What must occur for hardy weinberg equilibrium to occur?

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.
