Question

Drag each sequence to the correct location in the table. Sort the sequences based on the type of mutation they display. TATTA → TATTAGA TATTCG TATTAAT → TATTAT TATTACG ACGTATTC → ACGTTTC ATTA GTAC → ATGT ACTA GATCCAT → GATCCATCA TACTTAGT → TACTTGT

Answer 1

TATTA → TATTAGA (Insertion)

TATTCG TATTAAT → TATTAT TATTACG (traslocation)

ACGTATTC → ACGTTTC (deletion)

ATTA GTAC → ATGT ACTA (translocation)

GATCCAT → GATCCATCA (insertion)

TACTTAGT → TACTTGT (deletion)

Step-by-step explanation:

Mutation is any change that occurs in the nucleotide sequence of a gene. It can be of different types depending on how it occurs. In this question, insertion, deletion and translocation mutations were portrayed.

Insertion mutation occurs when one or more nucleotide bases is added to the original sequence. Deletion mutation is when one or more nucleotide bases are removed from the sequence. Translocation mutation is said to occur when one segment of a gene cuts off and is reattached to another gene sequence.

TATTA → TATTAGA

GATCCAT → GATCCATCA

These two cases are insertion mutations because bases "GA" and "CA" are added respectively to the original sequences

ACGTATTC → ACGTTTC

TACTTAGT → TACTTGT

The above cases are deletion mutations because bases "T" and "A" has been removed from the first and second original sequence respectively.

TATTCG TATTAAT → TATTAT TATTACG

In the above case, nucleotide bases "CG" and "AT" has cut off from the first and second original sequences respectively and got reattached to one another. This is an example of translocation mutation.

ATTA GTAC → ATGT ACTA

Also, in this case, "TA" and "GT" has detached from their original sequences and rettached in the opposite direction. Another example of translocation mutation.
