Here's a slightly more detailed explanation:
Transcription is the process where a DNA sequence is used as a template to create a complementary RNA sequence. This RNA sequence is called messenger RNA (mRNA).
The process involves:
* Unwinding of the DNA double helix.
* Pairing of RNA nucleotides (A, U, G, C) with their complementary DNA bases (T, A, C, G) on one strand of the DNA.
* Formation of a new RNA molecule that is a copy of the DNA sequence, but with uracil (U) instead of thymine (T).
* Release of the mRNA molecule from the DNA template.
This mRNA molecule then travels out of the nucleus and is used as a blueprint to create proteins in the process called translation.
