Reassociation kinetics of three satellite components of calf thymus DNA.
Using absorption measurements the reassociation kinetics of three satellite DNA components isolated from calf thymus was studied under various conditions. A different method using CsC1 density gradient determinations particularly suited for kinetic analysis of mixtures was also used and shown to give similar results. Reassociation rate constants were corrected for mismatching during strand reassociation using data obtained by kinetic analysis of fractions of the 1.714 g/cm-3 satellite component. The values of corrected as well as uncorrected complexities were calculated and compared with results of other methods. They were shown to be compatible with the concept of sequence repetition at various levels.
