Definition of revertant in English:

revertant

adjective rɪˈvəːt(ə)ntrəˈvərt(ə)nt

Biology

(of a cell, organism, or strain) having reverted to the normal type from a mutant or abnormal form.
this reverses the defect and creates revertant bacteria that do not require histidine
Example sentencesExamples
- This gives the appearance of directed mutagenesis because only revertant cells survive mutagenesis.
- If the same maximum copy number is used, there will also be a distinct effect on the fitness relative to revertant cells.
- This process culminates when haploid lac +revertant cells overgrow the original clone of cells with an amplification.
- The bodywall muscle in these revertant animals is also indistinguishable from wild-type muscle when viewed under polarized light (data not shown).
- As a complementary approach, chromosomal revertant mutants of cdc7 - PD1 were isolated in the hope that mutations that promote septation and counteract the septation defect of cdc7 - PD1 would be identified.

noun rɪˈvəːt(ə)ntrəˈvərt(ə)nt

Biology

A revertant cell, organism, or strain.
vaccine virus revertants
Example sentencesExamples
- As this point approaches, the plated population is mostly dead and the majority of surviving cells are Lac+ revertants.
- The numbers of revertants and viable cells were counted after incubation for 2 days at 37°C.
- A lower intensity of mutagenesis can explain all observed revertants if each mutagenized cell has multiple copies of the lac operon.
- We again found that most cosQ revertants were true revertants.
- Our urine mutagenicity testing did not provide evidence of increased numbers of bacterial strain revertants.
