Central Dogma of Molecular Biology from DNA to RNA to Protein, discussing the principles underlying the transfer of information in a biologic system and its regulation.
However, recent research seems to challenge certain aspects of Crick’s Central Dogma.
Does the Central Dogma still stand today? If not, can you find an example for a type of information transfer that is not explicitly covered by the Central Dogma (or even violates it)?
True or False?
Eukaryotic genomes are organized into operons; each operon consists of a series of genes which code for enzymes involved in a metabolic pathway, under the transcriptional control of a single promoter sequence .
Remember remove the introns! All introns start with GT and end with AG.
