Princeton's WordNet

  1. genetic code(noun)

    the ordering of nucleotides in DNA molecules that carries the genetic information in living cells


  1. genetic code(Noun)

    the set of rules by which the sequence of bases in DNA are translated into the amino acid sequence of proteins


  1. Genetic code

    The genetic code is the set of rules by which information encoded within genetic material is translated into proteins by living cells. Biological decoding is accomplished by the ribosome, which links amino acids in an order specified by mRNA, using transfer RNA molecules to carry amino acids and to read the mRNA three nucleotides at a time. The genetic code is highly similar among all organisms, and can be expressed in a simple table with 64 entries. The code defines how sequences of these nucleotide triplets, called codons, specify which amino acid will be added next during protein synthesis. With some exceptions, a three-nucleotide codon in a nucleic acid sequence specifies a single amino acid. Because the vast majority of genes are encoded with exactly the same code, this particular code is often referred to as the canonical or standard genetic code, or simply the genetic code, though in fact some variant codes have evolved. For example, protein synthesis in human mitochondria relies on a genetic code that differs from the standard genetic code. Not all genetic information is stored using the genetic code. All organisms' DNA contains regulatory sequences, intergenic segments, chromosomal structural areas, and other non-coding DNA that can contribute greatly to phenotype. Those elements operate under sets of rules that are distinct from the codon-to-amino acid paradigm underlying the genetic code.

  1. Genetic Code

    The meaning ascribed to the BASE SEQUENCE with respect to how it is translated into AMINO ACID SEQUENCE. The start, stop, and order of amino acids of a protein is specified by consecutive triplets of nucleotides called codons (CODON).

  1. genetic code

    Ever since the first genetic sequence was elucidated in the 70s, biotechnology has fast evolved into an information science. Scientists have already compiled the three gigabytes that spell out the human genetic code—a quantity of information that might fill more than 2,000 standard computer diskettes. But that’s just the initial trickle of a flood of knowledge to be tapped from the Human Genome Project. Considering that the project aims to identify all the estimated 80,000 genes in human DNA, the sequences of its three billion chemical bases will definitely be deciphered by the end of 2005. And once these genes are known, the data available will be mammoth, as scientists try to understand how these genes impact health and diseases.

Examples of genetic code in a Sentence

  1. Professor Deborah Fuller:

    In our paper, we replicated experimentally in monkeys a situation that [was] similar to the 2009 influenza pandemic, where a new strain of influenza unexpectedly emerged and current vaccines offered little or no protection, we vaccinated the monkeys with the same antigens included in the inactivated vaccine that year, but then also added, via our DNA vaccine, the genetic code for conserved influenza antigens. When we challenged the monkeys with the 2009 pandemic strain of influenza, we saw significant protection in the group that got the vaccine. They experienced only a transient low infection that was quickly cleared, when compared to the group that didn’t get the vaccine.

  2. Professor Deborah Fuller:

    The current flu vaccine is an inactivated virus, the whole virus is first grown in eggs, then it’s inactivated and injected. DNA vaccines are different. Instead of producing the vaccines in eggs, we instead inject a genetic code for proteins from the virus into our own cells. Our cells then read the code and produce the viral proteins, [aka] antigens. When our immune system sees the antigens, it makes immune responses that can protect against influenza infection.
