Definition of transposon in English:

transposon

noun -nz-trɑːns-transˈpəʊzɒntran(t)sˈpōˌzän

Genetics

A chromosomal segment that can undergo transposition, especially a segment of bacterial DNA that can be translocated as a whole between chromosomal, phage, and plasmid DNA in the absence of a complementary sequence in the host DNA.
〔遗传〕转座子，转位子。亦称JUMPING GENE
Also called jumping gene
Example sentencesExamples
- To me however, the most interesting components of junk DNA are the mobile genetic elements, also called jumping genes or transposons.
- Several DNA sequences that show sequence similarity to transposons were isolated from these sex chromosomes.
- Thus we were able to clone the DNA sequence that flanked the transposon insertion using plasmid rescue.
- The DNA transposons resemble typical bacterial transposons, they have terminal inverted repeats which enclose the transposase gene.
- In fact, in evolutionary terms, it is likely that such sequences have been more successful as transposons than as host genes.

Origin

1970s: from transposition + -on.
