Question

Cassify these sequences based on their potential to modify protein products. The plain letters in the sequences represent protein coding regions, and the bold letters represent noncoding regions.
Chance of Alteration in Protein NO Alteration in Protein




TACCTTAATT → TACCTTAATT
ATTGAGACCGT → GAGACCAGT
TATAATATTA → TATATATTA
ATTCATCTGG → ATTCATCGTGG
TACCTACT → TACCTACT
GATCTTACTT → GATCTTACTT

Answer 1

1) TACCTTAATT → TACCTTAATT 

For this item, we can notice that the first sequence is exactly identical to the second sequence. With this information, we can therefore assume that no alteration has been made to the protein.

ANSWER: NO Alteration in Protein

2) ATTGAGACCGT → GAGACCAGT 

Since I do not know the bolded letters, I am not sure whether the region that was lost in the second sequence (ATT) is a noncoding region. Nevertheless, we can see that the second sequence is missing another A aside from the three initial letters.

ANSWER: Chance of Alteration in Protein

3) TATAATATTA → TATATATTA 

Like the previous item, an A is also missing in the second sequence for this item. The missing A comes in between the second and third T. Without the bolded letters, I cannot be sure whether this missing A is a noncoding region or not, but anyway this still indicates a chance of alteration in protein.

ANSWER: Chance of Alteration in Protein

4) ATTCATCTGG → ATTCATCGTGG 

There is also one missing letter in this item like the previous two items. This time, it is the letter G that's supposed to be in between the rightmost C and T. Not knowing the bolded letters, we can still say that this missing G is a chance of alteration in protein.

ANSWER: Chance of Alteration in Protein

5) TACCTACT → TACCTACT

In this item, we can notice that the first sequence is exactly identical to the second sequence, just like the one in the first item. With this, we can therefore assume that no alteration has been made to the protein.

ANSWER: NO Alteration in Protein

6) GATCTTACTT → GATCTTACTT

We can also notice in this item that the second sequence is still the same as the first sequence. Thus, this information will tell us exactly what we have concluded for items #1 and #5. Having no change in the sequence would definitely mean that the protein is not altered.

ANSWER: NO Alteraton in Protein
