Document Summary

Transcapsidation when a plant becomes infected by two closely related viruses they could exchange their coat proteins. This new coat could change what organisms it infects. Unlikely in hawaii - only one type of potyvirus infects papaya. Usually the other virus would need to be closely related (sequence homology) for recombination. Rna interference is a biological process in which rna molecules inhibit gene expression, typically by causing the destruction of specific mrna molecules. Also known as co-suppression, post transcriptional gene silencing (ptgs: ptgs post transcriptional gene silencing. Rna interference: rna interference silencing gene expression by targeted degradation of mrna using short ds-rnas, synergy, recombination, risc, how to perform. Killer cells: casp a multiprotein complex that incorporates one strand of a small interfering rna (sirna) or microrna (mirna). Risc uses the sirna or mirna as a template for recognizing complementary mrna. It makes up of long chains polysaccharides of mainly galacturonic acid.
