Because we need paper and maple coasters and furniture.
Answer:
A. The RNA polymerase subunits of the P.syringae strain probably have extra flexibility so that they can move more freely in colder temperatures.
Explanation:
Because there is no difference in the amount of the RNA polymerases but rather their activity, the difference lies in their structure and not their sequence. Hence the answer can't be (B) or (D). Adaptations are made to broaden the conditions of survival. Hence E. coli would not limit it's survival by limiting its growth to warmer temperatures. Hence the answer is (A) the RNA polymerase subunits of the P. syringae strain probably have extra flexibility so that they can move more freely in colder temperatures.
Answer: Option 2) .the information on the strand changes
Explanation:
The rearrangement of nucleiotides in a DNA strand could be reversing the position of a chromosomal segment (Chromosomal inversions) OR interchanging the genetic parts of chromosomes (Chromosomal translocation)
In either case mutations occur because the information on the strand changes.
