#Unit 13. Methods in Biology

Sometimes the S1 nuclease will not digest the single stranded regions completely, so the transcript appears to be a little longer than it really is, But another method, called primer extension, can tell the 5’-end (but not the 3’-end) to the exact nucleotide

Rough ER, which is associated with ribosomes, functions in the synthesis and processing of secreted and membrane proteins

Smooth ER, which lacks ribosomes, functions in lipid synthesis.
