Question

Implement a class, Gene, that represents a gene. The string representation of the gene will only contain the letters, 'G', ' T ' and ' A '.

The class should contain the following
Constructor
a) _init__(self, dna)
Instance Variables
1) dna string representation of a sequence of nucleotides, e.g., 'GGGTTAAA'
Methods
i) getDNA () -returns the value of the instance variable dna
ii) getNucleotideAt(idx) -returns the mucleotide at position idx in dna; In other words, it returns the letter at position idx in the dna string
iii) mul (other) - returns a new Gene object whose dna is a crossover of itself and other. For the crossover operation, take the first half of the gene from one object and the second half of the gene from the other object. For example, the genes 'GGGTTAAA' and 'TTAAGAGA' after crossover would be 'GGGTGAGA'

Answer 1

To implement a class Gene that represents a gene, you can define a class with a dna attribute and methods to retrieve the DNA, get nucleotides at specific indices, and perform a crossover operation.

Step-by-step explanation:

To implement a class Gene that represents a gene, you can define a class with the following attributes and methods:

• Attributes: DNA (string representation of the gene)
• Methods: get DNA (returns the value of the DNA attribute), getNucleotideAt(IDX) (returns the nucleotide at the specified index), and mul(other) (returns a new Gene object with a crossover of the DNA)

class Gene:

To use the Gene class, you can create an instance of the class by passing the DNA sequence as a parameter to the constructor. Then you can call the various methods on the instance to retrieve the DNA, get nucleotides at specific indices, and perform a crossover operation.
