In the early twentieth century, biologists thought that proteins carried genetic information. This was based on the belief that proteins were more complex than DNA. Phoebus Levene's influential "tetranucleotide hypothesis", which incorrectly proposed that DNA was a repeating set of identical nucleotides, supported this conclusion. The results of the Avery–MacLeod–McCarty experiment, published in 1944, suggested that DNA was the genetic material, but there was still some hesita… Webhypothesis for extracting dna from strawberries - Example.

WebDNA can be divided functionally into three categories: (1) genes — which code for proteins or specify non-messenger RNAs; (2) semons — short specific sequences involved in the replication, segregation, recombination or specific attachments of chromosomes, or chromosome regions (e.g. loops or domains) or selfish genetic elements; (3) secondary … The immortal DNA strand hypothesis was proposed in 1975 by John Cairns as a mechanism for adult stem cells to minimize mutations in their genomes. This hypothesis proposes that instead of segregating their DNA during mitosis in a random manner, adult stem cells divide their DNA asymmetrically, and retain a distinct template set of DNA strands (parental strands) in each division. By retaining the same set of template DNA strands, adult stem cells would pass mutati…
