In this session some variations to the standard mechanisms of DNA replication, transcription and translation are discussed. The minor differences in DNA replication, transcription and translation in eukaryotes, prokaryotes, and viruses are discussed as a way to more fully understand the important processes involved in the copying and expression of genomes.

Shown below is the genomic structure of the human β-globin gene. The numbers within the boxes indicate the length (in nucleotides) of each region. The DNA sequences corresponding to the start codon and the stop codon are indicated. Which regions are present in the initial transcript?
Both introns and exons are present in the initial transcript.
What is the length (in nucleotides) of the mature, processed β-globin mRNA?
