Protein Synthesis

Lesson 4 of 4

Learning Targets

• If given a DNA segment (gene), I can Transcribe, mRNA process, and Translate the gene into an amino acid chain.

Multiple Choice

Which 'summarizes' the key stages / steps of Protein Synthesis?

• DNA to RNA to Amino Acids
• Amino Acids to RNA to DNA
• RNA to DNA to Amino Acids
• DNA to Amino Acids to RNA

Multiple Choice

Once built, amino acid chains will ____ 'automatically' in order to form a functional molecule.

• Fold
• Activate
• Terminate
• Simulate

Multiple Choice

Three mRNA bases in sequence are referred to as...

• A Gene
• A Triplet
• A codon
• An Anti-codon

Multiple Choice

Three DNA bases in sequence are referred to as...

• A Gene
• A Triplet
• A codon
• An Anti-codon

Multiple Select

The purpose of mRNA processing is to...

• Remove Exons from the RNA

• Remove Introns from the RNA

• Check the mRNA for mutations

• Make the mRNA from DNA code

• Add 5' Cap and Poly A tail to mRNA

Multiple Choice

Brings the amino acids to the ribosome.

• mRNA
• tRNA
• rRNA
• DNA

Multiple Choice

The process of 'reading' an mRNA to make a protein is called... (RNA to Amino Acid Chain)

• Replication

• Transcription

• Translation

• Cell Division

Multiple Choice

The process of making an mRNA strand from a DNA template is called

• Replication
• Transcription
• Translation
• Protein Synthesis

Find the 'start' of this gene below. Then transcribe the DNA code into a mRNA sequence. Please do this on a piece of paper. DO NOT REMOVE ANY INTRONS, yet:-)

TAT AAA TAT AAA TAC GGC CAT TTC ACC AAT ACA TCA ATT CAA TTT

Fill in the Blanks

Write your mRNA sequence for the DNA gene from the previous slide. Place one space between your RNA codons, but no space between the letters of the codon.

TAT AAA TAT AAA TAC GGC CAT TTC ACC AAT ACA TCA ATT CAA TTT

The proper mRNA sequence would be...

AUG CCG GUA AAG UUA UGU AGU UAA GUU AAA

Identify the 'intron' that is in this mRNA, cut it out and rewrite the combined pieces of mRNA that remain (Exons).

Fill in the Blanks

Using the same procedure to input your sequence. Input the sequence of the processed mRNA after you have removed the intron.

Unprocessed mRNA:

AUG CCG GUA AAG UGG UUA UGU AGU UAA GUU AAA

TRANSLATION: Write down the amino acid sequence as you will input this on the next slide.

mRNA to translate: AUG CCG UGG UUA AGA AGU UAA GUU AAA

Fill in the Blanks

AUG CCG UGG UUA AGA AGU UAA GUU AAA

Please transcribe the RNA, remove introns and then translate the DNA sequence below into an amino acid chain. Please use paper to do your work.

TAT AAA TAC GCC AAG GCC CAG GGA ATC CCA AAG ACT TAT CCA TTC

Fill in the Blanks

Input your amino acid sequence. Place one space between your amino acids. Use abbreviations.
