To determine which species the unknown species is most closely related to, we can compare its DNA sequence with the sequences of the known species.
The DNA sequence for the unknown species is:
**ACT GCA CCC**
Now, let's review the sequences of the known species:
- **Species I**: ACA GCA CCG
- **Species II**: ACT GGT GGA
- **Species III**: ACA GCA GGG
- **Species IV**: ACT GCA CCG
Now, let's compare the unknown species' sequence with each of the known species, focusing on the matching bases (nucleotides).
### Comparison:
1. **Species I**: ACA GCA CCG
- Differences:
- 1st position: A vs. A (match)
- 2nd position: C vs. C (match)
- 3rd position: A vs. T (difference)
- 4th position: G vs. G (match)
- 5th position: C vs. C (match)
- 6th position: A vs. C (difference)
- 7th position: C vs. G (difference)
- 8th position: C vs. C (match)
- Total matches: 5 match / 3 differences
2. **Species II**: ACT GGT GGA
- Differences:
- 1st position: A vs. A (match)
- 2nd position: C vs. C (match)
- 3rd position: T vs. T (match)
- 4th position: G vs. G (match)
- 5th position: C vs. G (difference)
- 6th position: A vs. T (difference)
- 7th position: C vs. G (difference)
- 8th position: C vs. A (difference)
- Total matches: 4 matches / 4 differences
3. **Species III**: ACA GCA GGG
- Differences:
- 1st position: A vs. A (match)
- 2nd position: C vs. C (match)
- 3rd position: A vs. T (difference)
- 4th position: G vs. G (match)
- 5th position: C vs. C (match)
- 6th position: A vs. G (difference)
- 7th position: G vs. G (match)
- 8th position: G vs. C (difference)
- Total matches: 5 matches / 3 differences
4. **Species IV**: ACT GCA CCG
- Differences:
- 1st position: A vs. A (match)
- 2nd position: C vs. C (match)
- 3rd position: T vs. T (match)
- 4th position: G vs. G (match)
- 5th position: C vs. C (match)
- 6th position: A vs. C (difference)
- 7th position: C vs. G (difference)
- 8th position: C vs. C (match)
- Total matches: 6 matches / 2 differences
### Conclusion:
- For **Species I**, there are **5 matches / 3 differences**.
- For **Species II**, there are **4 matches / 4 differences**.
- For **Species III**, there are **5 matches / 3 differences**.
- For **Species IV**, there are **6 matches / 2 differences**.
The unknown bacterial species is most closely related to **Species IV**, as it has the highest number of matches and the lowest number of differences.
