What is DNA's alphabet?
We use unique codes everyday; alphabets are also unique codes. Let's take the word "koala". In English, the letters 'k', 'o', 'a', 'l' and 'a' as particular order mean an dog that lives in Australia and also eats eucalyptus leaves. If an individual didn't know any English, you wouldn't have the ability to guess what the word means in the letters that are in the item. The letters 'k', 'o', 'a', and 'l' appear in parcels of other words where they don't mean anything regarding koalas. Different languages use different alphabets to convey meaning.
DNA's code is written in only four 'letters', called A, C, T and G. The meaning of the code lies in the sequence in the letters A, T, C and G just as that the meaning of a word lies in the sequence of alphabet characters. Your cells read the DNA sequence to produce chemicals that your body needs to survive.
