Gel Electrophoresis is a way to sort and measure the DNA strands. Scientists use the technique whenever they need to sort DNA strands according to lengths, this is because it helps them determine patterns, banding patterns create unique fingerprint for a certain individual. During the process the shorter strands move faster because they have less mass compared to the longer strand. Therefore, the short strands end up farther away from the starting point than the longer strands, which is how the different in lengths sort themselves out.
Answer:
The correct answer would be A) many coniferous trees.
Taiga and tundra represent the two coldest biomes of the land on the planet.
The average annual temperature of taiga lies between 41° Fahrenheit and 23° Fahrenheit whereas the temperature of the tundra lies below 23° Fahrenheit throughout the year.
It makes the major difference between the plant life of the two biomes. The taiga is characterized by the presence of coniferous forests which consist of spruces, pines, and larches.
In contrast, vegetation in the tundra is mainly composed of grasses, shrubs, mosses, sedges, and lichens.
