Sentence examples for altered genetic code from inspiring English sources

To find out, the researchers transferred the altered genetic code into pig embryos, a number of which they implanted in surrogate sows.

Following the adaptation of individual proteins, a discrete but altered genetic code could be re-established.

This latter interpretation is most in keeping with the single example of an organism that has been evolved to have an altered genetic code.

We show here that RF1 knockout and the introduction of an orthogonal tRNA/synthetase pair completely reassigned UAG from a stop signal to an amino acid, setting an initial stage for a bacterium to adopt this altered genetic code.

Because of their altered genetic code, fragments of mitochondrial genomes inserted into nuclear genomes are expected to be nonfunctional and hence to evolve in a neutral fashion, but in mammals, only ∼10% of substitutions at silent sites of active mitochondrial genes (in the mitochondrion) are capable of going to fixation (Lynch 2007).

In addition, the ambiguity of the UAG codon may hinder the eventual fixation of an altered genetic code to an organism, because protein products truncated at the UAG sites can interfere with normal protein functions and have detrimental effects on the host cell, thus preventing advantageous coding from being inherited and selected in directed evolution.

Extant organisms harboring altered genetic codes are at the end-point of the code evolution.

Furthermore, extant altered genetic codes vary in the number of codons assigned to different amino acids.

There are no records of the initial causes of or responses to such altered genetic codes; further adaptations to and details of eventual fixation are completely unknown.

Whereas GMO seeds generally contain altered DNA or genetic code from other species, this new program is more like an accelerated, science-aided version of old fashioned breeding: scientists use gene mapping techniques to identify desired traits in plants, making it easier for breeders to select for these characteristics.

Mutations shown only at the amino acid level were converted to single-nucleotide changes when it was possible to predict the altered base using the genetic code.
