P3 Quiz 😸

What is the primary objective of the assignment?

• To practice using 2D arrays while simulating basic DNA sequencing algorithms.

• To use while loops to simulate a patient prioritizer system.

• To dance dance the night away using arrays.

• To create a basic social network visualizer system through String manipulation.

What does the method indexOfNucleotide(char) do?

• Takes a char nucleotide to find as a parameter and returns the index that the nucleotide is located at in the NUCLEOTIDE class constant

• Calculates the probability of each nucleotide’s occurrence

• Computes the count of each nucleotide at each position

• Returns the most likely DNA sequence

What is the return type of the counts method?

• 2D array (int[][])

• String[]

• double[][]

• char[]

What does the 2D array returned by counts represent?

• • Each row corresponds to a position in the DNA sequences.

  • Each column corresponds to one of the nucleotides.

• • Each column corresponds to a position in the DNA sequences.

  • Each row corresponds to one of the nucleotides.

• • Each row corresponds to a position -- either 0, 1, or 2

  • Each column corresponds to one of the nucleotides.

• • Each column corresponds to a position -- either 0, 1, or 2
