Exploring the Journey from DNA to Protein

The video explains the central dogma of biology, detailing how DNA is transcribed into RNA and then translated into proteins. It begins with the assembly of factors at a gene's start, leading to the transcription process where DNA is copied into RNA. This RNA then moves to the cell's outer part, where ribosomes translate it into proteins, such as hemoglobin, by reading the genetic code and assembling amino acids.
