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.
