Polypeptide synthesis - transcription and splicing

Transcription:

Process of making pre-mRNA using part of the DNA as a template

• DNA helicase acts on a sepcific region of the DNA causing the two strands to separat and expose the nucleotide bases in that region
• The nucleotide bases on one of the two DNA strands (template strand) pair with their complementary nucleotides from the pool which is present in the nucleus
• The enzyme RNA polymerase then moves along the strand and joins the nucleotides together to…
