    Transcript

    00:02 So less, let's take a look at how we break down or digest are nucleic acids.

    00:09 The nuclei of all ingested cells in our food are going to contain both DNA and RNA within the pancreas, we have pancreatic nucleases which are able to hydrolyze nucleic acid into their nucleotide monomers.

    00:27 Also in the small intestines, we have brush border enzymes known as nucleotidases as well as phosphatases which are able to break the nucleotides down into free nitrogenous bases, pentose, sugars and phosphate ions.

    00:45 These are the three things that make a nucleic acid a nucleic acid.

    00:51 The breakdown products of this are now going to be actively transported by special carriers in the epithelium of the Villi of the small intestine.

    01:04 So to summarize the digestion of nucleic acids.

    01:07 Nucleic acid digestion is going to occur in the small intestines by both pancreatic and brush border enzymes.

    01:15 The subunits of a nucleic acid its pentose sugar.

    01:19 It's nitrogenous base and its phosphate are then going to be absorbed into the blood and transported to the liver.
