The following shows the DNA recognition sequences for three restriction enzymes:
BglII: Sau3AI: BamHI:
5’...A^GATCT...3’ 5’...^GATC...3’ 5’...G^GATCC...3’
3’...TCTAG^A...5’ 3’...CTAG^...5’ 3’...CCTAG^G...5’
(A) You are working with a short linear double-stranded DNA fragment that has the sequence shown below. Make boxes that encompass the binding sites for each enzyme, and label them:
5 '3'
3 '5'
(B) How many fragments do you expect if you cut with BgII alone?
(C) Write out the sequences of each double-stranded fragment you will get after cutting with BamHI, Make sure to label the 5' and 3' ends of each strand of your fragments.
(D) How many fragments do you expect if you cut with BglII alone? How many fragments do you expect if you cut with Sau3AI alone? How many fragments do you expect if you cut with BamHI and BglII?

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.
