The regulation of protein synthesis in cells involves the coordination of several different mechanisms. Discuss TWO of the specific mechanisms of gene regulation in eukaryotic cells from the list below and describe how the timing and coordination of these two mechanisms is important to gene regulation. (5 points) DNA packaging RNA processing/editing Alternative splicing mRNA degradation

Which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements.which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements.the framework of a membrane is a bilayer of phospholipids with their hydrophilic heads facing the aqueous environment inside and outside of the cell and their hydrophobic tails clustered in the center.because membranes are fluid, membrane proteins and phospholipids can drift about in the membrane.the diverse proteins found in and attached to membranes perform many important functions.the kinky tails of some proteins keep the membrane fluid by preventing the component molecules from packing solidly together.membranes include a mosaic, or mix, of carbohydrates embedded in a phospholipid bilayer.
