What are the sites on eukaryotic cell)Prokaryotes called that regulate gene expression during transcription?
Why is gene regulation important in Eukaryotes?
Regulatory eukaryotic cell)
Gene regulation in Eukaryotes allows for cell specialization
Transcription #1 200
What is the function of the promoter? eukaryotic cell)
Transcription #1 300
How does the lac repressor turn regulate transcription in off the lac genes in the lac operon?
When an mRNA is being transcribed, what is Polymerase edited out and what is kept in?
What is this object leaving the nucleus after transcription?
What is the part of a Eukaryote’s DNA that signals where the RNA polymerase is to begin transcribing?
The TATA Box is the promoter the RNA polymerase is to begin transcribing?
region in eukaryotes
Begins at the “ wraps around the mRNA?Start” codon AUG
(Remember: It’s the month we start school)
AUG codes for Methionine (Met)
Amino ribosome by the tRNA’s during translation?
Translation #1 400
When do tRNA’s ribosome by the tRNA’s during translation? stop bringing amino acids to the ribosome during translation?
Polypeptide chain released into cytoplasm
and the ribosome falls off of the mRNA which
is disposed of by the cell.
Translation #1 500
Translate ribosome by the tRNA’s during translation? this mRNA
A U G U G C G U C U A A
This is TRANSLATION!!!
Translation #2 100
What process is taking place when you use this wheel?
Shows the GENETIC CODEThe process is TRANSLATION
6 is the maximum number or codons possible for an amino acid!
tRNA during translation?
Translation #2 400
Different codons during translation?
Different amino acids
Translation #2 500
Not a real picture during translation?
Gene mutation in mice.
Substitution = Point Mutation (gene) during translation?Deletion = Frame Shift Mutation (gene)Insertion = Frame Shift Mutation (gene)
Inversion = Chromosomal Mutation
I bet he can catch 3x more flies!
Mutations for 200
The amino acid sequence is no longer the same because the codons have shifted
Mutations for 300
Mutations for 400 chromosomal mutations
What genes control the basic plan for where organs and tissues are to go in an embryo?
Hox Genes tissues are to go in an embryo?
NOT a real picture!!!
Mutations for 500
