noun ˈɡwɑːnəsiːnˈɡwänəˌsēn

    Example sentencesExamples
    • Standards (adenosine, cytidine, guanosine, pseudouridine, and uridine) were used to determine the optimal gradient conditions for separation.
    • This clearly indicates that the stems are primarily stabilized by the quartet-cation interactions, which are very similar for inosine and guanosine due to close similarity in their electronic structures.
    • Inosine is read as guanosine during translation and may alter the amino acid sequence of the encoded protein.
    • Since guanosine is not converted to adenine nucleotides in flies, guanosine must somehow act indirectly, perhaps through a mechanism for balancing nucleotide pools.
    • It is a methyl guanine which fools the virus into ‘thinking’ it is a cyclic sugar guanosine it needs for growth.
