Transcription Flashcards
1
Q
What is the process of transcription
A
Process that make pre-mRNA using a strand of DNA as a template
2
Q
Is the template strand coding or non-coding
A
Non-coding
3
Q
Step 1
A
DNA helicase, unzips DNA and hydrogen bonds are broken this exposes free nucleotides
4
Q
Step 2
A
RNA nucleotides align by complementary base pairing (uracil bind to adenine instead of thymine)
5
Q
Step 3
A
RNA polymerase joins adjacent nucleotides and phosphodiester bonds form
6
Q
What does transcription produce
A
Pre - mRNA
7
Q
What occurs to turn pre-mRNA into mRNA
A
Splicing
8
Q
What is the process of splicing
A
Removes introns and functional exons are joined
9
Q
Where does mRNA leave the nucleus
A
Nuclear pore
