Answer:
Membrane Lipid Rafts.
Explanation:
They are present in all cells and have been implicated in a variety of sorting and signaling processes. They are rich in cholesterol, sphingomyelin, and glycosylphosphatidylinositol (GPI)-anchored proteins; have more ordered acyl side chains; and are thicker than nonraft bilayer domains.
 
        
             
        
        
        
Answer:
The map distance between sn and ct is = 25 m.u or map unit.
Explanation:
Given, sn ct+  ×  sn+ ct 
In F1 generation the progenies were interbred.
In F2 generation,
sn ct = 13  (recombinant)
sn ct+ = 36  (parental)
sn+ ct = 39  (parental)
sn+ ct+ = 12 (recombinant)
<em>Linkage Map distance = (no. of Recombinant progeny/total progeny)   </em>
<em>                                                                                                                      × 100                              </em>
<em>Recombination frequency = (no. of Recombinant progeny/total progeny)                               </em>
<em>                                                                                                                     × 100</em>
                                             = ( 13+ 12) /100 × 100 m.u
                                              = 25/100  × 100
                                               = 25 %                                      
∴ The distance between sn and ct   = 25 m.u or map unit 
∴  Linkage happened  between sn and ct  as the map distance is much less than 50
