Welcome to Biological Science Advanced Studies. This site is designed for biology students of A-level, AS and A2, covering the related topics in Biology and Human Biology.
- a section of DNA unzips. hydrogen bonds between DNA bases break
-2 DNA strands separate and one strand becomes the template. Nucleotides attach to the exposed bases of the template strand by complementary base pairing
-RNA polymerase joins the nucleotides together to form a single strand of mRNA
-once mRNA has formed, the DNA unzips again
-pieces of mRNA called introns are spliced out of the mRNA
