guanine guanine  /ɡ ˈwɑ ˌnin/

Definition(s):

  • (n) a purine base found in DNA and RNA; pairs with cytosine

Usage(s):

  1. Since adenine sticks only to thymine and cytosine only to guanine, all the team had to do was end each strand with a nucleotide that would adhere to the one that began the next.
  2. It has since been learned that a substance was missing from their blood: an enzyme forbiddingly named hypo-xanthine-guanine phosphoribosyltrans-ferase, or PRT in the trade.

  1. Researchers extend human epigenomic map

    New research describes the dynamics of DNA methylation across a wide range of human cell types. Chemically, these marks are the addition of a methyl group -- one carbon atom surrounded by three hydrogen atoms -- anywhere a cytosine nucleotide sits next to a guanine nucleotide in the DNA sequence.

  2. HSCI researchers extend human epigenomic map

    ( Harvard University ) New research by the Harvard Stem Cell Institute's Alex Meissner, published online as a letter in the journal Nature, describes the dynamics of DNA methylation across a wide range of human cell types. Chemically, these marks are the addition of a methyl group -- one carbon atom surrounded by three hydrogen atoms -- anywhere a cytosine nucleotide sits next to a guanine ...
