SNPs are small variations in the genetic code which may be linked to particular traits, abilities or disease risks. (sciencedaily.com)
If you are reading a news story where it says, for example, scientists find the genetic contributors to diabetes or some other condition or trait, you're probably reading about SNPS. (genome.gov)
With enough people in our study, we can use the SNPs as markers to see that certain areas of the genome appear to be the same in people who have diabetes, and that tells us where we should look in more detail for a genetic cause. (genome.gov)

The key prerequisites to expand the genetic code are: the non-standard amino acid to encode, an unused codon to adopt, a tRNA that recognises this codon, and a tRNA synthetase that recognises only that tRNA and only the non-standard amino acid. (wikipedia.org)
The tRNA recognizes a specific three nucleotide codon in the mRNA with a complementary sequence called the anticodon on one of its loops. (wikipedia.org)
Each three-nucleotide codon is translated into one of twenty naturally occurring amino acids. (wikipedia.org)
There is at least one tRNA for any codon, and sometimes multiple codons code for the same amino acid. (wikipedia.org)
A feature exploited in the expansion of the genetic code is the fact that the aminoacyl tRNA synthetase often does not recognize the anticodon, but another part of the tRNA, meaning that if the anticodon were to be mutated the encoding of that amino acid would change to a new codon. (wikipedia.org)
First, for successful translation of a novel amino acid, the codon to which the novel amino acid is assigned cannot already code for one of the 20 natural amino acids. (wikipedia.org)
In 1961, Nirenberg, a biochemist from the National Institute of Arthritic and Metabolic Diseases, described the first base 'triplet,' a set of three nucleotides that make up a codon. (news-medical.net)
This meant that more than one codon could code for one amino acid, thus making the code redundant. (news-medical.net)
Seven years after the first codon of the genetic code was described, Nirenberg, Khorana, and Holley received the Nobel Prize in Physiology or Medicine in 1968. (news-medical.net)
Each amino acid is encoded for by 3 nucleotides termed a codon. (addgene.org)
This set of three nucleotides is called a " codon ," and different codons may code for the same amino acid. (sciencebuddies.org)
If we consider all codes mapping the 64 codes into 20 amino acids and one stop codon, there are more than 1.51×10 84 possible genetic codes. (biomedcentral.com)

adenine (A), thymine (T), guanine (G), and cytosine (C). This DNA code is turned into RNA (ribonucleic acid) in our bodies in a process called transcription . (sciencebuddies.org)
In a gene, if a single DNA nucleotide is mutated, for example from an adenine (A) to a guanine (G), this may cause the wrong amino acid to be made. (sciencebuddies.org)
Adenine (A) is one of the four nucleotide bases in DNA, with the other three being cytosine (C), guanine (G) and thymine (T). Within a double-stranded DNA molecule, adenine bases on one strand pair with thymine bases on the opposite strand. (genome.gov)
Each nucleotide contains one of four bases: adenine (A), cytosine (C), guanine (G), and thymine(T). A and T are complements while G and C are complements. (uaf.edu)
These instructions are carried in the form of DNA, a molecule composed of four nucleotides: adenine (A), cytosine (C), guanine (G), and thymine (T). (technia.com)
With the development of sequencing techniques, it is now possible to study the structure of the genome in detail, defined by the order of the nitrogenous bases (nucleotides) adenine, guanine, cytosine and thymine in the DNA. (lu.se)

For example, if three cytosine nucleotides are added sequentially to the same fragment of DNA, the light emitted will be three times more intense than fragments of DNA with only one cytosine nucleotide added. (news-medical.net)
If no light is emitted upon the addition of cytosine, then the next complimentary base in the single-strand DNA template must be one of the other three nucleotides. (news-medical.net)
DNA is composed of alternating sugar and phosphate groups, with the sugar attached to 1 of 4 possible nucleotide bases (adenosine, cytosine, guanine, thymidine). (cdc.gov)

In order to test our hypothesis that the multiobjective approach is useful for the analysis of the genetic code adaptability, we implemented a multiobjective optimization algorithm where two objectives are simultaneously optimized. (biomedcentral.com)

Abnormalities in these substances can indicate that there are changes in the DNA that underlie a genetic disorder. (medlineplus.gov)
Huntington's disease is an example of an autosomal dominant genetic disorder. (genome.gov)
Sickle cell anemia is an example of an autosomal recessive genetic disorder. (genome.gov)

Many claims have been made that nucleotides of DNA have been produced in such 'spark and soup' experiments. (bibliotecapleyades.net)
In fact, most experiments involve editing only two to three nucleotides close to the CRISPR cut site. (jhu.edu)

The dramatic population expansions that occurred over the past couple thousand years had a profound consequence on our genetic variability. (curezone.com)

Nucleobases dictate the genetic code (A, C, G, U), straying away from these nucleobases can cause transcription to stop. (uwo.ca)

Prof. Schunkert explains the finding: "This protective effect against cardiovascular disease cannot be attributed to educational attainment alone -- it is clear that genetic make-up also has a strong influencing role. (sciencedaily.com)
Sequencing of DNA gives a direct picture of our genetic make-up, while sequencing of the RNA that is naturally present in cells gives a picture of which parts of our non-coding DNA are used and in what way. (lu.se)

To be precise, 81 nucleotides in the viral genetic code were gone. (medicalnewstoday.com)

And the tower is only made of these four metal nucleotides, in the same double helix way as it is in reality (with some artistic exceptions). (irtc.org)
the buildings (made of polygons), the CSG cars, the people at the base, the four nucleotides at the base. (irtc.org)
However, nucleotides are much more complex than the simple amino acids made by Miller and Urey, and would require much more chemical expertise to produce. (bibliotecapleyades.net)
DNA is made of a sequence of nucleotides bound to another sequence of complementing nucleotides in a double helix. (uaf.edu)
Every species on Earth - bacteria, animals, humans - has the same genetic structure, made up of four units. (scrippsnews.com)

The instructions necessary to produce all the living structures on earth are 'written' by the rules of the genetic code and carried by these chains of chemical letters. (bibliotecapleyades.net)

A mutation is a change in a genetic sequence," he said. (medicalnewstoday.com)
Using as objectives the robustness against mutation with the amino acids properties polar requirement (objective 1) and robustness with respect to hydropathy index or molecular volume (objective 2), we found solutions closer to the canonical genetic code in terms of robustness, when compared with the results using only one objective reported by other authors. (biomedcentral.com)
Genetic mutation promotes biological evolution and results in biodiversity ( 2 , 3 ). (spandidos-publications.com)
