Describe and discuss different approaches for finding motif in genetic string.
Introduction:
DNA, RNA and Proteins, these are three types of very large molecules essential for every living organism, for their biological functioning. Each molecule, DNA, RNA and Protein, play a vital role in living organisms, without them no life could survive. Let’s understand functionality one by one:
• DNA consists of encoded instructions which are necessary to maintain, assemble and reproduce.
• Proteins play important role in movement, photosynthesis, vision etc.
• RNA is used to make proteins from encoded instructions in DNA.
From above, we can conclude that, DNA makes RNA and RNA makes proteins.
Let’s discuss each term one by one
Genetic string: “Genetic” string or sequence is used in a biological world to represent any string made up of biological sequence consisting of a chain of similar subparts. Usually genetic strings are considered for any of the following three strings.

1. DNA strings: Known as DeoxyriboNucleic Acid (DNA). DNA is the main reason behind functioning and development of all living organisms. Usually, DNA molecule looks like a double helix because it contains two biopolymer strands arranges such that they looks like they are coiling around each other. DNA is made up from one of the four nucleotide, guanine (G), adenine (A), thymine (T), or cytosine (C). DNA strings are made up of alphabets {A, C, G, T}.…
