WebWhat are cryptic splice acceptor and donor sites and how does this influence altemative splicing? What does it mean when scientists say that the Open reading frame must be maintained if altemative splicing can produce functional proteins? aslation of mRNA g: Chapter 15: Translation of. WebPrecise pre-mRNA splicing, essential for appropriate protein translation, depends on the presence of consensus "cis" sequences that define exon-intron boundaries and regulatory sequences recognized by splicing machinery. Point mutations at these consensus sequences can cause improper exon and intron … Webeliminates splicing from the wild-type donor site, but activates a cryptic splice site in the middle of exon 1 in vitro (Felber et al, 1982).
