RNA is isolated from the rough endoplasmic reticulum of several tissues, subjected to electrophoresis, blotted, and probed with a 32P-cDNA. The results from the autoradiogram are shown below (bands present only in liver, pancreas, testes, and adipose tissue at 2.4 kb). The 32P-cDNA probe used on the blot most likely is specific for which of the following genes?

1. A)Lipoprotein lipase
2. B)Scavenger receptor SR-B1GABARITO
3. C)Apoprotein B100
4. D)Apoprotein B48
5. E)Apoprotein CII
