[Q4] DNA Evolution Models

According to the assumptions made for both Jukes-Cantor and Kimura 2 Parameter (K2P) models about the substitution rates (either α or β), and taking into account the restrictions for Markov models, it is correct to say about the range of possible values for them that:

1. Any of the rates α and β in K2P have a larger range than α in Jukes-Cantor.
2. The range of α in Jukes-Cantor is larger that any of the ranges for α and β in K2P.
3. Only depending on the value of α in K2P it is possible to conclude anything about the size of the ranges of β in K2P with respect to α in Jukes-Cantor.
4. Only depending on the value of β in K2P it is possible to conclude anything about the size of the ranges of α in K2P with respect to α in Jukes-Cantor.
5. None of the above

[Q3] Sequence Comparison

The main reason why it is acceptable a saving of space while increasing the execution time with the improvement for the basic sequence comparison algorithm is:

1. It is imperative to save space at any cost since the processing of normal sequences for real problems demands more RAM than any average computer can have nowadays.
2. The increment in execution time is merely theoretical, considering the processing capacity of current computers.
3. The increment in execution time is constant with this improvement.
4. Time complexity remains the same with this improvement.
5. None of the above

[Q2] Informatics Concepts

Let Q_s be the set containing all the subsequences of string S and T_s be the set of all the substrings of string S. It is correct to say that:

1. Q_s ⊆ T_s
2. T_s ⊆ Q_s
3. Q_s ⊂ T_s
4. T_s ⊂ Q_s
5. None of the above
