Some restriction enzymes cut at specific and unambiguous sequences (e. g., noti at gcggccgc). as such, the distance between two such sites in a large random dna sequence is 48, assuming a 50% g+c dna content. however, the sequence recognized by xhoii is said to be ambiguous (pu-gatc-py, where pu = any purine and py any pyrimidine). what, therefore, is the expected distance between two xhoii sites in a large random sequence?

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.

explanation:

the endomembrane system i think

condenser is used to focus in the light microscope.

well, since there is no answer choices, i will give an answer on how it works : )

the two objects are placed together. energy will always be transferred from the hotter object to the cooler object until they are equal. hope this is close to one of the answer choices : )
