o Codon = ___________________________________________ (each codon codes for an amino acid… example: AUG codes for __________________/methionine
o Know how to use the codon wheel/chart!!
Know the processes of:
*Replication: original DNA strand to complimentary DNA strand
Example: original DNA: AAA TTG CCG
replicated DNA: TTT AAC GGC
(write the replicated strand below): TAC TTA CCG TCA ATC
____________________________________________________
*Transcription: process of transcribing DNA to mRNA
original DNA: AAA TTG CCG
mRNA: UUU AAC GGC (phenylalanine asparganine glycine)
Practice (transcribe this original DNA strand): TAC TTA CCG TCA ATC
____________________________________________________
Corresponding AA sequence? ____________ ____________ ____________ ____________ ____________
*Translation: mRNA translates a message to tRNA
original DNA: AAA TTG CCG
mRNA: UUU AAC GGC,
tRNA: AAA UUG CCG
Practice (translate this original DNA strand): TAC TTA CCG TCA ATC
____________________________________________________
