Furthermore, I think the only time something is 3’-5’ is when DNA/RNA polymerase is reading the template strand, however, even then it forms the new strand in the 5’-3’ direction since it is complementary to the template strand. You are correct in that DNA/RNA polymerase read the 3’-5 ...

WebbRibosomes are the structures where polypeptides (proteins) are built. They are made up of protein and RNA (ribosomal RNA, or rRNA). Each ribosome has two subunits, a large one and a small one, which come together around an mRNA—kind of like the two halves of a hamburger bun coming together around the patty.

Webb10 mars 2024 · These ribosome-protected mRNA fragments are commonly called RPFs or ribosome footprints. Mapping these sequenced RPFs to the transcriptome provides a ‘snapshot’ of translation that reveals the positions and densities of ribosomes on individual mRNAs transcriptome-wide. WebbThe ribosome gets started in a process called initiation. Several initiation factor proteins deliver the mRNA to the small subunit, line up the first tRNA, and guide the association with the large subunit.
