How is mrna transcribed without disrupting a dna molecule?
a. just like dna synthesis, mrna synthesis is done along small sections of dna that are uncoiled and the two strands separated.
b. once the mrna is created from one of the dna strands, that portion of the dna rejoins and recoils as more dna opens up further down.
c. in this way a continuous strand of mrna can be synthesized without uncoiling a long sequence of dna and separating the two strands.
d. only separating a small portion of the dna at a time reduces the probability of damage to the molecule.
e. view the animation below, then complete the quiz to test your knowledge of the concept.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg 

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
