Bioinformatics Map of the Beta-Globin Gene
Questions to Consider
- What is represented by the red letters? Black letters? Blue letters?
(Click to make image larger) - Which strand of DNA is considered the template strand? How do you know?

- Why are there three rows (reading frames) of amino acid data?
- Consider the region that is highlighted below. Is this an intron or exon?

- How many exons and introns does the beta-globin gene contain?
- When you completed this activity, you noticed that the exons were located in different reading frames. What caused this?
- What is the alternative splicing hypothesis?
