Question 6:

(1 mark)

An mRNA has the following codon:

5? GCA 3?.

What tRNA anticodon will bind to thiscodon?

The tRNA anticodon 5'  3' will bind to the mRNA codon5' GCA 3'.

**Please enter your sequence in the 5' to 3' direction.Deductions will be made if a sequence is inputted in the wrongdirection.**

QUESTION 7

Question 7:

(1 mark)

A tRNA anticodon has the following sequence:

3' CUA 5'.

What amino acid does it carry?

The amino acid carried on a tRNA with the anticodon 3' CUA 5' is.

**Hint: You will need to consult the genetic code to answer thisquestion. And watch your 5' to 3' direction.**

QUESTION 8

Questions 8 to 13 are based on the followinginformation.

Question 8:

The top strand of the following segment of DNA serves as thetemplate strand:

3’ TACACCTTGGCGACGACT 5’

5’ ATGTGGAACCGCTGCTGA 3’

We will refer to this segment of DNA as the original (orunmutated) sequence.

Please answer the following questions:

(a) What is the mRNA sequence?

The mRNA sequence is  5'  3'.

**Please enter your sequence in the 5' to 3' direction.Deductions will be made if a sequence is inputted in the wrongdirection.**

(b) Using the mRNA sequence you determined in part (a)of this question, give the sequence of the protein that would betranslated.

The amino acid sequence for this protein isN-terminus  C-terminus.

**Please note**

The N-terminus refers to the beginning of the primary sequencefor a protein, and the C-terminus refers to the end of the primarysequence for a protein.

i.e. input the amino acids in the order that they would betranslated.

If a codon encodes for a stop codon, type STOP.

When inputting your sequence, separate each amino acid with ahyphen (e.g. Ser-Tyr-STOP).

You will need to consult the genetic code to answer thisquestion.

QUESTION 9

Questions 9 to 13 are in reference to the DNAsequence shown in Question 8.

Question 9:

The original (unmutated) DNA sequence (shown above in Question8) has been mutated to the following (this represents the templatestrand):

3’ TACATCTTGGCGACGACT 5’.

We will refer to this sequence as mutation#1.

Please note that for simplicity only the template strand forthis mutated segment of DNA is shown.

Answer the following questions:

(a) What is the complete mRNA sequence for the mutatedsegment mutation #1?

The mutated mRNA sequence is  5'  3'.

**Please enter your sequence in the 5' to 3' direction.Deductions will be made if a sequence is inputted in the wrongdirection.**

(b) Using the mRNA sequence you determined in part (a)of this question, give the sequence of the protein that would betranslated.

The amino acid sequence for this protein isN-terminus  C-terminus.

**Please note**

The N-terminus refers to the beginning of the primary sequencefor a protein, and the C-terminus refers to the end of the primarysequence for a protein.

i.e. input the amino acids in the order that they would betranslated.

If a codon encodes for a stop codon, type STOP.

When inputting your sequence, separate each amino acid with ahyphen (e.g. Ser-Tyr-STOP).

You will need to consult the genetic code to answer thisquestion.
