Answer:
A. play a role establishing and maintaining membrane lipid asymmetry
Explanation:
Proteins that move move certain phospholipids between leaflets are transmembrane proteins via "flip-flop" transition have also the possibility to maintain membrane lipid asymmetry. There are few types of such proteins:
- flipases-move lipids from the exterior to the interior side of the membrane, energy required
- flopases-move lipids in reverse comparing to flipases, energy required
- scramblases-no energy required, bidirectional
Because of the action of those proteins, cytosolic side of plasma membrane differs from exoplasmic side (asymmetry).
Answer: knowing that the number of adenine will be always equal to the number of thymine.
Explanation:On the basis of base pairing rule, the purine bases bonds with the pyrimidine bases. This takes place as the configurations of pyrimidine and purine bases permit formation of hydrogen bonding between the two.
The base pairing rule suggests that the pairing of adenine takes place only with thymine and pairing of guanine takes place only with cytosine. Two hydrogen bonds are produced between an adenine and thymine base pair, while three hydrogen bonds are produced between a guanine and cytosine base pair.
