Semi Conservative Theory Of Dna Replication. After the incorporation of radioactive thymidine 3 h the root tips were transferred to unlabelled medium containing colchicine. 1958 also demonstrated the semi conservative mode of replication in dna and chromosomes in root tip cells of vicia faba.
This is called semiconservative replication. Dispersive replication proposed molecules composed of randomized fragments of double old and double new dna. 1958 also demonstrated the semi conservative mode of replication in dna and chromosomes in root tip cells of vicia faba.
During dna replication the double stranded dna helix unwinds with the help of the enzyme helicase and the strands are separated.
Semi conservative replication posits the creation of hybrid old new double helices. Semi conservative replication posits the creation of hybrid old new double helices. After the incorporation of radioactive thymidine 3 h the root tips were transferred to unlabelled medium containing colchicine. Semiconservative replication describes the mechanism of dna replication in all known cells.
