| Pronunciation (US): |  | (GB): | |
I. (noun)
Sense 1
Meaning:
The ordering of nucleotides in DNA molecules that carries the genetic information in living cells
Classified under:
Nouns denoting groupings of people or objects
Hypernyms ("genetic code" is a kind of...):
order; ordering; ordination (logical or comprehensible arrangement of separate elements)
Hyponyms (each of the following is a kind of "genetic code"):
triplet code (the normal version of the genetic code in which a sequence of three nucleotides codes for the synthesis of a specific amino acid)
Context examples:
Transposons, more commonly called jumping genes, are mobile snippets of DNA code that can copy themselves into new positions within the genome - the genetic code of an organism.

In the study, researchers tagged cells using a transposon, a piece of genetic code that can jump to a random point in DNA when exposed to an enzyme called transposase, to track blood progenitors and adult stem cells during the natural, unperturbed process of blood regeneration.

As a result, this agent interferes with the initiation complex between messenger RNA and the bacterial ribosome thereby causing the misreading of the genetic code resulting in the production of non-functional proteins, consequently leading to bacterial cell death.
