Q
What is transcription
A
A strand is copied into a complementary strand of mRNA because DNA cannot leave the nucleus because it is too big

Q
How does transcription happen
A
- DNA is untwisted in the parts that need to be copied
- DNA is unzipped by enzymes breaking the hydrogen bonds
- RNA polymerase pairs floating nucleotides with one of the unzipped strands of DNA base pairing rule
- Only one strand acts as a template, the other waits until process is over
- Enzymes separate the mRNA from the DNA template and the mRNA enters the cytoplasm and goes to a ribosome
- The strands of DNA zips back up reforming the hydrogen bonds
