Let's match the given changed nucleotide sequences to their respective mutations:
1. Deletion Mutation: In a deletion mutation, one or more nucleotides are removed from the DNA sequence.
- Original sequence: `CATTCACACG`
- Changed sequence: `CATTCACG`
Sequence `CATTCACG` results from removing the nucleotides `AC` from the original sequence `CATTCACACG`.
2. Insertion Mutation: In an insertion mutation, additional nucleotides are inserted into the DNA sequence.
- Original sequence: `CATTCACACG`
- Changed sequence: `CATTCACACCACG`
Sequence `CATTCACACCACG` is derived from inserting `CACAC` into the original sequence `CATTCACACG`.
3. Inversion Mutation: In an inversion mutation, a segment of the DNA sequence is reversed.
- Original sequence: `CATTCACACG`
- Changed sequence: `CATTECACAC`
Sequence `CATTECACAC` likely arises from reversing a segment `A` or changing `A` to `E` creating a similar pattern but with a change in the nucleotide order.
Based on the provided sequences, let's fill in the table appropriately:
[tex]\[
\begin{array}{|c|l|c|}
\hline
\text{Type of Mutation} & \begin{array}{l}
\text{Original Nucleotide}\\
\text{Sequence}
\end{array} & \begin{array}{c}
\text{Changed Nucleotide}\\
\text{Sequence}
\end{array} \\
\hline
\text{deletion} & \text{CATTCACACG} & \text{CATTCACG} \\
\hline
\text{insertion} & \text{CATTCACACG} & \text{CATTCACACCACG} \\
\hline
\text{inversion} & \text{CATTCACACG} & \text{CATTECACAC} \\
\hline
\end{array}
\][/tex]
Hence, the correctly matched sequences are:
- Deletion: `CATTCACG`
- Insertion: `CATTCACACCACG`
- Inversion: `CATTECACAC`
Some present sequences (`CATTCACACA` and `CATTTCACACG`) do not fit within the described mutation types based on the given solution.
