Genome-wide analysis of transcriptome data in Chlamydomonas reinhardtii shows periodic patterns in gene expression levels when cultures are grown under alternating light and dark cycles so that G1 of the cell cycle occurs in the light phase and S/M/G0 occurs during the dark phase. However, alternative splicing, a process that … WebThe relationship between cilia and cell cycle is enigmatic, but it may involve regulation by the NIMA-family of kinases (Neks).
