Mapping and Sequencing the Human Genome
A primary goal of the Human Genome Project is to make a series of descriptive diagrams maps of each human chromosome at increasingly finer resolutions.
Mapping
Mapping is the process of making a representative diagram cataloging the genes and other features of a chromosome and showing their relative locations.
gene mapping
the strategies that locate the position of gene loci on chromosomes

Association mapping is based on the idea that traits that have entered a population only recently will still be linked to the surrounding genetic sequence of the original evolutionary ancestor, or in other words, ...
Using restriction enzymes in mapping
When DNA from the same source is digested with a particular restriction enzyme it will always give a set of the same sized fragments.
A technique in which DNA restriction fragment length polymorphisms (RFLPs) are used as reference markers for mapping in relation to known genes or other RFLP loci.

Gene mapping
Determination of the relative positions of different genes on a DNA molecule.
Gene transfer agent
A phage-like agent from Rhodobacter capsulates species which can transfer DNA from the donor host to recipient cells.
The [mapping] of the genome may help immensely in terms of our studies. Certainly for the identification of new genes I think it will be great.
S1 end mapping: A technique to determine where the end of an RNA transcript lies with respect to its template DNA (the gene). Can't be described in a short paragraph. See "RNAse Protection assay" for a closely related technique.

Finally, the Human Genome Project was launched in 1990 with the goal of mapping the general human genome. This project was essentially completed in 2003, with further analysis still being published.
Through mapping studies, the authors were able to show that the copper tolerance gene and the gene responsible for hybrid inviability were either the same gene or were very tightly linked.
