Sunburns and aging skin are obvious effects of exposure to harmful UV rays, tobacco smoke and other carcinogens. But the ...

The sides of the DNA ladder consist of a long string of sugar and phosphate molecules, to which the bases are attached. Each sugar-phosphate-base combination is called a nucleotide. A nucleotide ...

The Summit supercomputer revealed how damaged strands of DNA are surgically repaired by a molecular pathway called nucleotide ...

A single DNA nucleotide, the base unit of the human genome, is a tiny, tiny thing. Each one is made up of only 30 atoms (plus or minus a few, depending on the base), making it much too small to be ...

DNA is always synthesized in the 5'-to-3' direction ... As shown in Figure 2, the 5'-phosphate group of the new nucleotide binds to the 3'-OH group of the last nucleotide of the growing strand.

Base substitutions are the simplest type of gene-level mutation, and they involve the swapping of one nucleotide for another during DNA replication. For example, during replication, a thymine ...

When that happens, investigators may look at all the variations, or single nucleotide polymorphisms, that are in the DNA sample. Those SNPs, or "snips," are then uploaded to a genealogy database ...

Researchers begin with a long strand of DNA, the scaffold, in solution. Because the nucleotide bases that make up DNA bind in a known way (adenine binds to thymine, and guanine binds to cytosine), the ...

DNA mutations are changes in the nucleotide sequence of the DNA molecule. Mutations can occur spontaneously due to errors during DNA replication or as a result of exposure to mutagens (e.g., UV ...

Kokoris came up with the idea of solving some of the noise issue of nanopore sequencing by converting DNA into larger ...

Natera (NTRA) announced that the U.S. Patent and Trademark Office has issued Natera a new patent related to testing of single nucleotide ...

Researchers have uncovered mechanisms by which mobile genetic elements integrate into the chromosomes of bacteria with linear genomes.
