Scientists identified 3.055 billion base pairs (“letters”) of our DNA code as they made the data public. However, the wait has been over two decades since the first draft was released in 2001. Scientists have known for decades that genes were spread across 23 pairs of chromosomes.

As long stretches of the genome remained unknown , scientists struggled to understand where millions of bases fit. While they released the first draft in 2001, the reference genome draft was released in 2013 where they had read these fragments more accurately.

The Human Genome Project that first realised its goal in 1988 aimed to decipher the human genome in three major ways:

• Determining the order, or "sequence", of all the bases in our genome's DNA
• Making maps that show the locations of genes for major sections of all our chromosome...
