Feature #4: Identifying Proteins
Explore how to identify potential proteins by checking if genome sequences are palindromic using recursion. This lesson guides you through implementing a recursive function that compares sequence characters, handles base cases, and analyzes the algorithm's time and space complexity.
We'll cover the following...
Description
We have an unknown sequence of genomes that is thought to be a new protein. To accept or reject this sequence as a new protein, one method we can use is to identify it as a palindromic sequence. A palindrome is a string that reads the same from the start as the end.
We’ll be provided with a sequence of genomes in the form of a string. Our task is to identify whether these genomes constitute a palindrome to be considered as a potential protein.
Solution
A recursive approach can be used to solve this problem. We can keep comparing the first and last elements of the string. If these values are equal, then the updated string, with the matched entries removed, can be sent to the recursive function.
Let’s see how we might implement this functionality:
-
Define the following base case:
- If the given sequence has a length equal to zero or one, it will
