Question

The sequencing of the human genome was an important step in understanding human genetic disorders like colorblindness. Through sescientists have been able to pinpoint the specific genes involved and which chromosomes they are located on. Order the steps of humansequencing below, with the first step at the top and the last step at the bottom.

Answer 1

1. Extract DNA from cells

2. Cut DNA using restriction enzymes to create smaller fragments.

3. Sequence each fragment.

4. Separate DNA fragments by size so fragments can be isolated.

5. Analyze fragment sequence for overlaps to create a complete genome.
