Genomics And Genome Projects

Question 1

How is an organisms genomic sequence obtained?

Answer 1

1) Obtain the organisms genomic DNA

2) Break the DNA into small fragments

3) Obtain the DNA sequence from all the fragments

4) Search for overlaps of identity between the DNA sequences of the different fragments to “reconstruct” the genome sequence

5) Fill in any missing “gaps” in the genome sequence

Question 2

How many genes are in the human genome?

Answer 2

30,000 - 40,000 genes
