Part 2

Where does transcription take place? (name part of eukaryotic cell)What are copied from DNA during transcription?


In the nucleus produces rna mrna trna rrna transcription 1 100

In the nucleus!Produces RNA (mRNA, tRNA, rRNA)Transcription #1 100


Part 2

What are the sites on Prokaryotes called that regulate gene expression during transcription?

Why is gene regulation important in Eukaryotes?


Part 2

Regulatory

Sites

Regulatory Sites Without these gene expression could not be controlled (turn on or off) in Prokaryotes

Gene regulation in Eukaryotes allows for cell specialization

Transcription #1 200


Part 2

What is the function of the promoter?


Binding site of the rna polymerase to begin making mrna

Binding site of the RNA Polymerase to begin making mRNA

Transcription #1 300


An is a group of genes that work together to regulate transcription in prokaryotes

An ______________is a group of genes that work together to regulate transcription in prokaryotes


Operon transcription 1 400

OperonTranscription #1 400


Part 2

How does the lac repressor turn off the lac genes in the lac operon?


By binding to the operator and blocking transcription by rna polymerase transcription 1 500

By binding to the operator and blocking transcription by RNA Polymerase Transcription #1 500

Part 2

When an mRNA is being transcribed, what is edited out and what is kept in?


Transcription 2 300

Introns

Out!

“junk”

Transcription #2 300

Exons In!


Part 2

What is this object leaving the nucleus after transcription?


Transcription 2 400

Transcription #2 400

mRNA


Part 2

What is the part of a Eukaryote’s DNA that signals where the RNA polymerase is to begin transcribing?

Hint:


Transcription 2 500

The TATA Box is the promoter

region in eukaryotes

for transcription.

Transcription #2 500


Where does the mrna go for translation to occur

Where does the mRNA go for translation to occur?


Out of the nucleus and into the cytoplasm to the ribosome translation 1 100

Out of the nucleus and into the cytoplasm to the ribosomeTranslation #1 100

Cytoplasm


Once the mrna is in the cytoplasm what rna recognizes and wraps around the mrna

Once the mRNA is in the cytoplasm, what RNA recognizes and wraps around the mRNA?


Rrna ribosomal rna translation 1 200

rRNA (ribosomal RNA)Translation #1 200


Where does the ribosome rrna begin reading the mrna what amino acid does this code for

Where does the ribosome (rRNA) begin reading the mRNA? What amino acid does this code for?


Translation 1 300

Begins at the “Start” codon AUG

(Remember: It’s the month we start school)

AUG codes for Methionine (Met)

Translation #1 300


What happens to the amino acids that are brought to the ribosome by the trna s during translation

What happens to the amino acids that are brought to the ribosome by the tRNA’s during translation?

Amino

Acid


Part 2

Amino

Acid

The amino acid joins the growing polypeptide chain (protein). The tRNA then leaves to find another amino acid.

Translation #1 400


Part 2

When do tRNA’s stop bringing amino acids to the ribosome during translation?


When a stop codon is reached on the mrna strand translation 1 500

When a STOP codon is reached on the mRNA strand.Translation #1 500

Stop

codon

Polypeptide chain released into cytoplasm

and the ribosome falls off of the mRNA which

is disposed of by the cell.

Translation #1 500

How many codons specify for the amino acid threonine what are they

What is the max possible number of codons for a single amino acid?

How many codons specify for the amino acid Threonine? What are they?


Translation 2 300

Threonine

What is a gene mutation

Not a real picture

What is a gene mutation?


Change in nucleotide sequence mutations for 100

Change in nucleotide sequenceMutations for 100


Part 2

Of the following mutations, which one of these is not a gene mutation?SubstitutionDeletion InsertionInversion

Gene mutation in mice.


Part 2

Substitution = Point Mutation (gene)Deletion = Frame Shift Mutation (gene)Insertion = Frame Shift Mutation (gene)

Inversion = Chromosomal Mutation

I bet he can catch 3x more flies!

Mutations for 200


What type of gene mutation is it when a nucleotide is inserted or deleted

What type of gene mutation is it when a nucleotide is inserted or deleted?


Frame shift gene mutation

The amino acid sequence is no longer the same because the codons have shifted

Frame Shift Gene Mutation
