SYNOPSIS. Guanine‐8‐3H is not a specific label for nucleic acids in Euglena gracilis (strain SM‐L1, streptomycin‐bleached), but is incorporated into all biochemical fractions. Autoradiographic results show that guanine is metabolized in, both the nucleus and the cytoplasm of these Eugelna, but nuclear metabolism of guanine occurs only at a very low level in carbon‐limited cells. Further, carbon‐limited Euglena incorporate less total guanine than do control Euglena in a comparable time period. However, the majority of label incorporated into the nucleic acid fraction of the carbon‐limited cells is incorporated into RNA.
