Day 32 has 41 protein-coding genes including APOB (apolipoprotein B). The APOB protein is the protein part of LDL (low density lipoprotein, or so-called “bad cholesterol”) particles, which shuttle cholesterol in your bloodstream.
APOB is a good example of a gene that is subject to RNA editing to make two versions of a protein. (This is different than alternative splicing – an actual letter of the RNA is changed rather than splicing different pieces together to make a different RNA.) In the small intestine, only the half of APOB protein is made, and this version makes chylomicrons which carry lipids from food to the blood.
