RNA synthesis
Transcription: Similar to DNA Replication
1. DNA DOUBLE HELIX Unwinds 2. DNA DOUBLE HELIX Unzips 3. RNA Polymerase uses 1 STRAND to create
mRNA
Use Promoters – tell the RNA polymerase where to stop and where to end
KEY DIFFERENCE: Only uses one strand from parental DNA NOT BOTH!
2 types of RNA
mRNA = messenger RNA
tRNA = transfer RNA
Same rules of pairing for both mRNA and tRNA
How are the base pairing rules different from DNA?
DNA or RNA?
CCC – GGG DNA, RNA, or Both?
CAT – GUA DNA, RNA, or Both?
UUU – AAA DNA, RNA, or Both?
TGC – ACG DNA, RNA, or Both?
