+
+## DNA Pattern Recognition
+
+Site: LeetCode\
+Difficulty per Site: Easy
+
+## Problem
+
+Biologists are studying basic patterns in DNA sequences. Write a solution to identify `sample_id` with the following patterns:
+
+* Sequences that start with ATG (a common start codon)
+* Sequences that end with either TAA, TAG, or TGA (stop codons)
+* Sequences containing the motif ATAT (a simple repeated pattern)
+* Sequences that have at least 3 consecutive G (like GGG or GGGG)
+
+Return the result table ordered by sample_id in ascending order. [[Full Description](https://leetcode.com/problems/dna-pattern-recognition/description/)]
