It makes sense that cell membranes are made of phospholipids because water cant mix in with lipids, so the phospholipids will be able to effectively block out any unwanted water or chemicals suspended in water outside of the cell.
-binds to DNA during transcription and separates the DNA strands
-then uses one strand of DNA as a template from which to assemble nucleotides into a complementary strand of RNA. Hope this helped. ;)
Because we can’t tunnel down, so in order to study the interior layers, we must use indirect methods.
