    Study Notes

    Protein Synthesis

    • Contains a gene which contains exons and introns
    • Exons called Exon 1, Exon 2, Exon 3, Exon 4
    • The gene undergoes transcription to produce a primary transcript, which is mRNA
    • The primary transcript undergoes splicing to become a mature transcript, mRNA
    • The mRNA undergoes protein synthesis

    SnapShot: Directed Differentiation of Pluripotent Stem Cells

    • This study is written by Luis A.Williams, Brand N. Davis-Dusenbery, and Kevin C. Eggan, from Harvard University
    • The study focuses on proteins acting on stem cells
    • This action leads to the formation, differentiation, and function of other cells
    • The paper discusses the derivatives which stem cells can become including endoderm, mesoderm, and ectoderm derivatives.
