Noun
morpholino (plural morpholinos)
(genetics) A structural analog of natural nucleic acid used to modify gene expression, in which the ribose or deoxyribose rings of nucleic acids are replaced with morpholine rings and the phosphodiester intersubunit linkages of nucleic acids are replaced with phosphorodiamidate linkages.
A common reverse genetics technique is to reduce gene expression or modify splicing using Morpholino antisense technology. Source: Internet
Morpholino oligonucleotides (MO) are stable, synthetic macromolecules that contain the same bases as DNA or RNA; by binding to complementary RNA sequences, they can reduce the expression of specific genes or block other processes from occurring on RNA. Source: Internet
