Transcription Flashcards
1
Q
What happens in transcription?
A
A molecule of mRNA is made in the nucleus
2
Q
Describe how mRNA is formed by transcription in eukaryotes (5)
A
Hydrogen bonds between DNA bases break and one DNA strand acts as a template
Free RNA nucleotides align by complementary base pairing
In RNA, Uracil base pairs with adenine on DNA
RNA polymerase joins adjacent RNA nucleotides by phosphodiester bonds
Pre-mRNA is spliced to form mRNA
