| Abstract: | The complete sequence of the flax 5S DNA repeat is presented. Length heterogeneity is the consequence of the presence or absence of a single direct repeat and the majority of single base changes are transition mutations. No sequence variation has been found in the coding sequence. The extent of methylation of cytosines has been measured at one location in the gene and one in the spacer. The relationship between the observed sequence heterogeneity and the level of methylation is discussed in the context of the operation of a correction mechanism. |
