For a bacterium containing a single chromosome, a genome project will aim to map the sequence of that chromosome. For the human species, whose genome includes 22 pairs of autosomes and 2 sex chromosomes, a complete genome sequence will involve 46 separate chromosome sequences. The Human Genome Project is a well known example of a genome project ...
The human genome is the total collection of genes in a human being contained in the human chromosome, composed of over three billion nucleotides. [2] In April 2003, the Human Genome Project was able to sequence all the DNA in the human genome, and to discover that the human genome was composed of around 20,000 protein coding genes.
The Human Genome Project was a 13-year-long publicly funded project initiated in 1990 with the objective of determining the DNA sequence of the entire euchromatic human genome within 13 years. [ 8 ] [ 9 ] The idea of such a project originated in the work of Ronald A. Fisher , whose work is also credited with later initiating the project. [ 10 ]
Low-resolution physical mapping is typically capable of resolving DNA ranging from one base pair to several mega bases. In this category, most mapping methods involve generating a somatic cell hybrid panel, which is able to map any human DNA sequences, the gene of interest [clarification needed], to specific chromosomes of animal cells, such as those of mice and hamsters.

Although the 'completion' of the human genome project was announced in 2001, [2] there remained hundreds of gaps, with about 5–10% of the total sequence remaining undetermined. The missing genetic information was mostly in repetitive heterochromatic regions and near the centromeres and telomeres , but also some gene-encoding euchromatic ...
This is the process that was initially used for the Human Genome Project, however due to stability issues, YACs were abandoned for the use of bacterial artificial chromosome. The bakers' yeast S. cerevisiae is one of the most important experimental organisms for studying eukaryotic molecular genetics. [1]
The Talking Glossary of Genetics is a science learning tool developed by the National Human Genome Research Institute (NHGRI) at the National Institutes of Health (NIH). NHGRI oversaw the NIH's role in the Human Genome Project, the international research effort aimed at mapping the genes in the human body and developing tools for gene discovery.
