Words similar to planaria
Example sentences for: planaria
How can you use “planaria” in a sentence? Here are some example sentences to help you improve your vocabulary:
Several DNA sequences similar to the mariner element have been reported in G. tigrina [ 10 16 ] . There are about 7000 copies of this element in the genome, which appear to code for an active transposase [ 10 ] . None of these mariner elements are present in the genomes of other turbellarians, including the species closest to G. tigrina [ 10 ] . With the aid of PCR using specific primers for the planarian mariner element, we isolated and sequenced several clones from sexual and asexual planaria.
In particular, the identities of five Antennapedia -like homeobox genes have been disclosed from both our and the Spanish asexual strains [ 11 26 ] . These findings imply that PEVE may affect other asexual strains of planaria, thus paving the way for the development of transgenic planaria using the planarian viral sequences as vectors for introduction of exogenous DNA into planarian cells.
Genomic DNA was isolated from planaria using a rapid extraction method [ 27 ] . DNA was further treated with RNase A for RNA degradation.
We performed PEVE analyses in asexual planaria from an independent Spanish population.
PCR with PEVE-specific primers of genomic DNA and cDNA, and Southern blot hybridization on genomic DNA did not reveal PEVE in planaria nucleic acid samples (data not shown).
