Ch. 10 – Translation

Answer the following questions in your own words.

1. In biology, what is the purpose of translation?

2. Where in the cell does translation take place?

3. How does the cell know where to begin translating the mRNA?

4. How does the cell know where to stop translating the mRNA?

5. Define codon. Include its function in the definition.

6. Fill in the blanks:

Proteins are made up of subunits called _____________ ___________ and there are __________ of these subunits found in nature.

7. The genetic code is described as degenerate. What does this mean and why is it beneficial?

8. The virus that causes Covid-19 is an RNA virus. This means that its genome is composed solely of RNA. Many of the vaccines being developed to prevent Covid-19 infections are actually segments of RNA that code for specific viral proteins. Vaccine recipients will be injected with these RNA segments and their cells will make the viral proteins that this RNA codes for.

a. What process will the cell use to do this?

b. Where in our bodies must the RNA segments get delivered to in order for this process to happen?

DNA RNA Protein

Below are four problems where you will practice transcription and translation. Remember that when you transcribe DNA to RNA, you follow the base pair rules but you replace T with U. This worksheet will review the processes of transcription and translation and introduce the concept of how mutations (changes in DNA sequence) can affect the proteins that the DNA codes for.

1. Below is a section of the gene that codes for normal hemoglobin. Transcribe this section of DNA into mRNA (ch. 9) and then translate the mRNA into the correct sequence of amino acids. (ch. 10) *Note this is just a section so there is no stop codon

There is a copy of the genetic code on the last page of this worksheet. You can use the 3 letter abbreviations for the amino acids.

DNA: TAC CCT GAC TGA GGA CTC CTC TTC AGA

mRNA:

amino acid sequence:

1. Sickle Cell disease can result from a single mutation in the above DNA sequence. The underlined thymine above is changed to a C below. Transcribe this section of DNA into mRNA and then translate the mRNA into the correct sequence of amino acids. Answer the question below.

Mutated DNA: TAC CCT GAC TGA GGA CCC CTC TTC AGA

mRNA:

amino acid sequence:

What happens to the amino acid sequence because of this change from a T to a C?

1. Mutations can occur at any position in the DNA sequence. Below is the normal DNA sequence and then a mutated sequence (the highlighted C is changed to a T). Transcribe and translate the mutated sequence and compare it to the normal sequence that you transcribed and translated in problem #1 above. Answer the questions below.

Normal DNA: TAC CCT GAC TGA GGA CTC CTC TTC AGA

Mutated DNA: TAC CCT GAC TGA GGA CTT CTC TTC AGA

mRNA:

amino acid sequence:

What happens to the amino acid sequence because of this change from a T to a C?

Is it likely that this mutation will lead to sickle cell disease? Why or why not?

Bonus question (up to 5 pts)

Sometimes mutations occur so that a nucleotide is removed from a DNA sequence. In the mutated sequence below, a nucleotide has been deleted due to a mistake during DNA replication. Transcribe this section of DNA into mRNA and then translate the mRNA into the correct sequence of amino acids. Answer the questions below.

Mutated DNA: TAC CCT GAC TGA GGA CCC TCT TCA GA

mRNA:

amino acid sequence:

How did the mRNA sequence change because of this deletion?

How did the amino acid sequence change because of this deletion?

Is it likely that this mutation will lead to sickle cell disease? Why or why not?

Ch. 11 Gene expression – Lactose tolerance activity

Watch the following HHMI documentary, “Got Lactase? The Co-evolution of genes and culture” about evolution of lactose tolerance. As you are watching the video, answer the following questions.

https://www.hhmi.org/biointeractive/making-fittest-got-lactase-co-evolution-genes-and-culture

1. All infant mammals can digest milk. T/F

2. What does the enzyme, lactase do?

3. Why are so many human adults lactose intolerant?

4. Why is lactose tolerance also called lactase persistence?

5. Worldwide, what percentage of human adults can digest milk?

6. Lactase persistence is prevalent in many areas of the world. T/F

7. Did researchers find a difference in the lactase gene between lactose tolerant and lactose intolerant people?

8. Think about it… What would be a possible effect of a mutation in the coding region of the lactase gene?

9. Where in the genome does the mutation occur that leads to lactase persistence?

10. What is a pastoralist?

11. Briefly explain how scientists determined that people in Africa and European settlements were using diary as a food source.

12. Provide two reasons why a mutation that led to lactase persistence would be a selective advantage in populations that used milk as a food source.

13. You are talking to your friend and they say, “I can’t eat ice cream because I don’t have the gene for the enzyme, lactase.” Explain why this statement is not correct. Provide a statement that would be correct and explain why a person might not be able to eat ice cream.

14. In your own words, explain how lactose intolerance is the result of a difference in gene expression.
