The genetic code is a nearly universal language that encodes directions for cells. The language uses DNA nucleotides, arranged in codons of three, to store the blueprints for amino acid chains.
DNA is the genetic code that codes for traits. There is a process called protein synthesis in which DNA is used as a template to code for mRNA. The mRNA leaves the cell nucleus after complementary base pairing is done. Then, tRNA binds to the mRNA (anticodon to codon).Attached to each tRNA molecule is an amino acid.NA is the genetic code that codes for traits. There is a process called protein synthesis in which DNA is used as a template to code for mRNA. The mRNA leaves the cell nucleus after complementary base pairing is done.
