However the former cloning methods such as map-base cloning or transposon tagging which based on forward genetics can only cloned one or several genes at the same time.

以往的基因克隆方法如图位克隆法、转座子标签法等大都是建立在正向遗传学的基础上，这些方法只适用于一个或少数基因，应该说是零敲碎打的策略。

Curiosity mission planner Dawn Sumner said photographs like the ones beamed back by the rover, as well as others taken by probes in orbit, will be used to map a path to the mountain's base -- "doing the best science we can along the way, but also keeping our eyes on that beautiful layered rock, " she said.

The genome project, which the government began in 1987, aimed to speed the gene-hunting effort by providing the first full map of all 3 billion base pairs that make up human DNA. (It was not necessary, in this effort, to run through all the pairs on each set of chromosomes, or 6 billion pairs.) And because the base pairs come in only four varieties, they are digital and ideal for computer decoding.
