主题：【求助】这句中的min是什么意思？是个单位吗，是啥单位？

原文由 poorlittle(poorlittle) 发表:From http://www.ncbi.nlm.nih.gov/books/NBK7908/figure/A470/?report=objectonly Positions of representative genes are indicated on inner circle. Distances between genes are calibrated in minutes, based on times required for transfer during conjugation. Position of threonine (thr) locus is arbitrarily designated as 0 minutes, and other assignments are relative to thr. On next circle, symbols and arrowheads identify specific Hfr donor strains of E. coli and their characteristics. For each Hfr strain the point of arrowhead is the origin for chromosomal transfer; oriented transfer of chromosome during conjugation proceeds from point of arrowhead, followed immediately by base of the arrowhead, and so on. F' plasmids are identified by numbers, and the fragment of the E. coli chromosome present in each F' plasmid is represented by an arc corresponding to a specific segment of the circular genetic map. See text for definitions of Hfr and F' donor strains and for description of the conjugal mating system in E. coli. From Bachman, B.M., Low, K.B. Microbiol Rev, 1980;44:31.

原文由 poorlittle(poorlittle) 发表:I searched with the key words “"circular genetic map" , E. Coli, min” and got: The origin of replication, oriC, of the E. coli K12 chromosome is located between the markers uncB and asn at 82.5 minutes on the circular genetic map.It seems that min stands for minute.
