Answer: Codon
Explanation: A codon is a triplet of nucleotides in an mRNA that codes for specific amino acids. There are 64 possible codons. They are called the genetic codes. Three of these codons (UAA, UAG, UGA) do not code any known amino acid and are thus called termination codons. One of the codons (AUG) signals the beginning of translation and is thus called initiation codon.
Answer:

A stroke is primarily caused due to reduced or interrupted supply of blood to the brain.
The blood supply is usually reduced as a result of blockage or bursting of an artery carrying blood to the brain.
