Identification of branch points and lariat RNAs during splicing in plants
Research, The Plant Cell, The Plant Cell: In a NutshellZhang et al. identified intronic branch points and lariat RNAs in four plant species.
By Binglian Zheng, Fudan University, China.
Background: Most genes contain exons and introns; when genes are transcribed into precursor mRNAs, the introns must be removed and exons ligated to form mature mRNAs…
