|
set of 3 nucleotides that specifies a particular amino acid
|
|
Reading Frame

dna>rna>protein
|
|
Transcription
|
flow of information to dna to rna
|
|

flow of information from rna to protein
|
|
stop codons
|
3 codons (UUA, UGA,UAG) genetic code used to terminate translation
|
|
start codon
|
(AUG) used to signify the start of translation
|
|
degenerate
|
remainder of the code, meaning that some amino acids are specified by more than one codon
|
|
template strand
|
strand of DNA, double helix used to make RNA
|
|
coding strand
|
strand of DNA that is complementary to the template strand
|
|
RNA Polymerase
|
the enzyme that synthesizes RNA from the DNA template
|
|
Messenger RNA

|
signal recognition particle
|
composed of protein and RNA and involved in directing mRNA to the SER

|
core polymerase
|
capable of RNA elongation but not the initition
|
|
holoenzyme
|
composed of the core enzyme the sigma factor whih is required for transcription initiation
