In 2000, when then-president clinton along with francis collins of the human genome project and craig venter of celera announced the completion of a "draft" of the human genome, the event did not, in fact, represent true completion because most of what types of sequences were not included?

The millions of sequences were not put up together from their end and had no repeating non-coding sequences.

Explanation:

Celera Venter of Gene Myers started working in collaboration with the Human Genome project which was designed as a revolutionary concept of sequencing of human genome at a large scale. Myers break through the traditional method of sequencing and proposed of an idea of sequencing in a unique way.  

He suggested the method of breaking genome copies and then sequencing them together using LINEs. However, the declaration of this proposal by the Human project had certain failures at first as it lacked the non-coding repeating sequence.
