Which was the last step in sequencing the human genome?

A. locating overlapping sequences

B. identifying genes by finding promoters

C. cutting the DNA into manageable pieces

D. sorting between introns and exons

Solution

The different steps for sequencing human genome includes:

1. Mapping

2. Building libraries

3. Subclones ( using bacterial artificial chromosomes)

4. E.coli to store and copy DNA

5. preparing DNA for sequencing reactions

6. Sequencing reactions

7. Products of sequencing reactions

8. Separating the sequencing products

9. Reading the sequencing products

10. Assembling the results. A computer program can integrate the data to spot where DNA fragments overlap and order them as they were originally on the chromosome.

Here the answer is A. Locating overlapping sequences.
