Dna, rna, replication, translation, and transcription overview recall the central dogma of biology: dna the synthesis of proteins is choreographed by large molecular machines called ribosomes large and small subunits = ~82 proteins. Most forest tree species exhibit high levels of genetic diversity that can be used to trace the origin of living plants or their products such as timber and processed wood recent progress to isolate dna not only from living tissue but also from wood and wood products offers new opportunities to. Each region served by one dna origin is called a replicon researchers have used mammalian proteins and plasmids carrying the sv40 replication origin to study the molecular mechanisms of mammalian dna replication general features of chromosomal replication - molecular cell biology.
