Calnan reported improvements in speech using a procedure that employed VY retroposition
and lengthening of the velum.
The team also found that the Rps23r1 gene, whose human counterpart has not yet been identified, was created through a process called retroposition
, in which a gene is duplicated through the reverse transcription (or reading) of mRNA and the duplicate is placed in a different location in the cell's DNA.

of the AFC family of SINEs (short interspersed repetitive elements) before and during the adaptive radiation of cichlid fishes in Lake Malawi and related inferences about phylogeny.
ALU elements multiply within the genome in a retroposition
process through RNA polymerase III-derived transcripts from evolution (13, 14); therefore, qPCR of ALU repeats with a properly designed primer set can dramatically increase the sensitivity of size-dependent DNA measurement.
Possible role of retroposition
and conversion events in its concerted evolution.
Proceeding this way prevents posterior teeth extrusion, vertical dimension growth, backward retroposition
of the mandible due to its clockwise rotation, and interlabial gap increase.
