Genetic code may be defined as the sequence of the triplet nucleotides that are heritable in nature. The codons code for the particular amino acids in the organism.
Genetic code is universal in nature. This means that the codon codes for the same amino acids in almost all the organism. The same genetic code is coded by the same amino acids in the bacteria as well as humans. Hence, the bacteria has the ability to produce the human protein as well.
Recombinant DNA is a technology scientists developed that made itpossible to insert a human gene into the genetic material of a commonbacterium. This “recombinant” micro-organism could now produce the proteinencoded by the human gene. Scientists build the human insulin gene in the laboratory.
