mRNA, tRNA, rRNA
13
Q
What is the process called to replicate DNA?
A
Semi conservative replication
14
Q
What is the process called to turn DNA into mRNA?
A
Transcription
15
Q
Describe the process of transcription
A
- One strand of DNA acts as a template strand to construct mRNA molecule
- RNA polymerase links to the template strand and inserts mRNA nucleotides one at a time according to the rules of complementary base pairing
- Stop sequence- ends mRNA, RNA polymerase leaves
