Many genetic technologies involve the transferring of genes from one organism to another. For example, a gene in human DNA codes for the production of insulin, an important protein. This gene has been transferred to bacterial DNA, where it remains functional. The bacteria produce human insulin that can be harvested and given to people who lack sufficient insulin supplies. Which property of molecular genetics is most useful for explaining the success of the technology used to manufacture insulin?

Dale Hernandez · Answer 1

The universality of genetic code.

Explanation:

The DNA is a molecule made up from 4 different nucleotides (A, T, C or G). The sequence in which these nucleotides are ordered constitute a code that gives a cell instructions to produce a specific protein. This is called the genetic code.

Every three nucleotides code for a specific amino acid. For example, ACG codes for Arginine, CUC codes for Proline, and so on.

The genetic code is universal. This means that in all living organisms, a particular sequence of three nucleotides will code for the same amino acid. This property guarantees that the human gene that codes for human insulin will also code for human insulin in bacteria.

The genetic code is identical in nearly all organisms.
