Why is it necessary to unzip the DNA for transcription to occur?

because the new DNA needs an original strand as well a new strand, thanks to helicase. that's why it is considered "semi-conservative". Unzipping the DNA allows an official copy to be made.

During transcription what molecule opens the DNA?
Helicase is what will "unzip" the DNA.
Does transcription occur in DNA or RNA?
Transcription occurs in DNA to produce mRNA.
What DNA begins to uncoil DNA?
DNA helix uncoils the DNA for transcription to occur.
DNA replication and transcription occur in the what?
Nucleus.
Which process does a DNA unzip?
to make a new copy before the cell splits

DNA helix uncoils the DNA for transcription to occur.
DNA replication and transcription occur in the what?
Nucleus.
Does transcription occur in the nucleus or at the nucleoid?
Yes transcription occurs inside the nucleus of the cell.
What must happen to the DNA before transcription can take place?
It must unwind and separate for transcription to occur
Which process does a DNA unzip?
to make a new copy before the cell splits
Transcription and translation are the two processes necessary to change?
DNA to protein.
Where does the transcription occur in protein?
Transcription occurs when DNA creates mRNA. In a Eukaryotic cell, this occurs inside the nucleus.
What determines where on the DNA molecule transcription begins and ends?
An RNA primer will attach to the unzipped DNA molecule signaling the beginning of transcription and transcription will occur until the DNA molecule is completely copied (the end is when there is no more DNA molecule to replicate).
Where in the cell do replication translation and transcription occur?
Most of the DNA in a eukaryotic cell is in the nucleus, and that is where DNA replication and transcription occur.In eukaryotic cells, mitochondria and chloroplastsalso contain DNA, which performs replication and transcription inside these organelles.In prokaryotic cells there is no nucleus. The DNA is in a region of the cytoplasm called the nucleoid, and that is where DNA replication and transcription occur in these cells.
Which process must occur before DNA information is moved out of the nucleus by mRNA?
Transcription must occur .
