Question 2

What is the first stage of transcription? ⚙️⚙️⚙️

Answer 2

DNA double helix unwinds

Question 3

What is the second stage of transcription? 🔨🔨

Answer 3

Weak hydrogen bonds between base pairs break, separating the two DNA strands

Question 4

What is the throat stage of transcription? 🤝

Answer 4

Free nucleotides pair with their complementary partners on the DNA strand

Question 5

What is the fourth stage in transcription? 💔

Answer 5

Hydrogen bonds form between complementary bases

Question 6

What is the fifth stage of transcription? 💚💚

And what is this catalysed by?

Answer 6

Strong covalent bonds form between the phosphate and sugar of neighbouring nucleotides.
This is catalysed by RNA polymerase
