The video tutorial covers the genetic code, its characteristics, and its role in protein synthesis. It explains the concept of codons, including start and stop codons, and the universal nature of the genetic code with some exceptions. The tutorial also discusses the non-overlapping and degenerate nature of the code, the codon-anticodon recognition process, and the wobble hypothesis. Additionally, it introduces the concept of cistrons in genetic expression and provides multiple-choice questions for exam preparation.
