DNA strands must unwind and the two strands must separate prior to transcription beginning. Once transcription is complete, the two strands join back together.

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.
How is bacterial translation different from eukaryotic translation?
Bacteria can begin translation before transcription has terminated.
What k must happen before meiosis can begin?
A duplication of the chromosomes is what must happen before meiosis can begin.
Are promoters signals in RNA that indicate RNA polymerase when to begin transcription?
I found this information in my Biology textbook.
The process of transcription is similar to the process of DNA?
Replication and transcription involves a parental DNA strand that is the foundation on which the products are built on.Replication and transcription both have initiation step which involve the breakage of the parental DNA strand.Replication and transcription both have specific proteins that keep the polymerase molecule attached to the parental DNA strand. There are elongation factors for transcription and sliding clamp for replication.Both processes use DNA topoisomerases to relieve supercoiling.Both processes only proceed in the 5' to 3' direction.Replication and transcription both involve the addition of specific 3' endings. In replication, it is the addition of the GGGTTA sequence by telomerase. In transcription, it is the addition of the poly-A tail.Both processes used nucleotides as the language on which the daughter strands come from.Replication and transcription involve the hydrolysis of a phosphodiester bonds to begin their process.Both processes take place in the nucleus.

What must happen before meiosis can begin?
DNA replicates and forms tetrad—APEX.
What 2 things happen to DNA strand before DNA can be replicated helicase cause?
Before replication can begin, the following two molecular processes occur:Helicase binds to DNAHelicase causes the complimentary strands to separate by breaking the hydrogen bonds between the nucleotide bases, causing the replication bubble to form.
What enzyme unzips the DNA molecule?
There are several enzymes that 'unzip' DNA. These enzymes are collectively known as DNA helicases. DNA helicases are helix-destabilizing enzymes that bind to DNA at the origin of replication and break hydrogen bonds, thereby separating the two strands. This allows RNA polymerase to begin transcription (copying) of the DNA sequence.
What happen before a blizzard?
The primary things that happen before a blizzard are a drop in temperature and an increase in cloud cover. The sky will begin to darken as the imminent storm approaches.
When and where did the war for independence from Great Britain begin did it begin before or after the Declaration of Independence?
Before Lexington and Concord happened before. But most major battles didn't happen til after.
Are promoters signals in RNA that indicate RNA polymerase when to begin transcription?
I found this information in my Biology textbook.
Does transcription begin at a promoter region and continue until RNA polymerase reaches a stop codon?
yes,
