Question
In Avery's Bombshell experiment, treatment of _____ with DNase blocked transformation. smooth cell Streptococcus pneumonia cells rough cell Streptococcus pneumonia cells smooth cell Streptococcus pneumoniae cell-free extract rough cell Streptococcus pneumoniae cell-free extract None of the above In the endogenous pathway for plasma lipoprotein transport, what lipoprotein is produced in the liver for delivery of cholesterol and cholesterol esters to extrahepatic tissues (i.e., muscle, adipose)? LDL Chylomicrons HDL VLDL Bile saltsExplanation / Answer
12. smooth cell Streptococcus pneumoniae cell-free extract.
Averys bombshell experimented with bacterial transformation by adding genetic material to change the properties of organisms. They transformed a rough (non disease causing) stain to a smooth stain (did cause disease, capsule). He took smooth colonies and killed them, collected molecules and formed a cell free extract and mixed with rough cells, some rough took up the smooth and incorporated it into its genome making rough cells into smooth cells.
13. In the endogenous pathway for plasma protein transport, low density lipoprotein (LDL) is produced in the liver for delivery of cholesterol or cholesterol esters to extrahepatic tissues.
