transcription

• what is the function of dna helicase

  unwinds the DNA double helix to separate the 2 strands
• what is the function of the enzyme rna polymerase

  this binds the template strand at the beginning of the sequence to be copied
• how many stands are used as a template strand for the transcription mrna

  one
• where are free rna nucleotides used in transcription

  they align with the opposite complementary bases after dna polymerase has bound the template strand
• what enzymes are used in transcription , in order of use

  dna helicase and rna polymerase
• list the order in which transcription takes place

  a template strand is formed as mrna , then dna helicase is used to unzip the dna double helix and break the hydrogen bonds between them , then rna polymerases binds the template strand at the beginning so the sequence can be copied and then free rna nucleotides align with the complementary bases on the template strand
• where does the mrna leave the nucleus

  trough the nuclear pore
