Match the genetic mutations with their names.
dusya [7]

Answer:

1. CGAGGTT → CGTT (Deletion)

2. ATTCGG → ATTCGGATTCGG (Duplication)

3. CTTAAT → TAATTC (Inversion)

4. CTTAAT → CTTAACGCT (Insertion)

5. CGAT → CTAT (Substitution)

6. CCGGTT + TTAGGC = CCGTTA + GTTGGC (Translocation)

Explanation:

1. CGAGGTT → CGTT (Deletion) ---- This is called deletion because it involves the removal of 3 base pairs (AGG) from the DNA sequence.

2. ATTCGG → ATTCGGATTCGG (Duplication) ---- In this case, the particular sequence (ATTCGG) is copied again or duplicated.

3. CTTAAT → TAATTC (Inversion)----- This is called inversion mutation because the DNA sequence breaks off and is reattached but this time in a reverse order i.e. CTT becomes TTC, placing the last base first and the first base last.

4. CTTAAT → CTTAACGCT (Insertion) ------ This is called insertion mutation because it involves the addition of extra base pairs (CGC) into the sequence. The Insertion occurs between the last A and T nucleotide.

5. CGAT → CTAT (Substitution) ----- This is called substitution because Guanine base is replaced by Thymine in the DNA sequence. It is specifically called a transversion substitution because a purine (Guanine) is replaced by a pyrimidine (Thymine). It is called a point mutation because it involves a single base.

6. CCGGTT + TTAGGC = CCGTTA + GTTGGC (Translocation) ----- in this case, CCGGTT and TTAGGC are sequences on different chromosomes. Portions of sequence on the first chromosome (GTT) and second chromosome (TTA) breaks off and gets reattached/exchanged in each other i.e. the first chromosome gets TTA while the second gets GTT. This kind of mutation is called translocation.
