Answer:
B. The ddNTPs lack a 3′ hydroxyl group.
Explanation:
Dideoxynucleotides is a family of inhibitors of the DNA polymerase, its official name is 2',3' dideoxynucleotides but they are commonly called ddNTPs. One of the main characteristics of this compound is the absence of the 3'-hydroxyl group in the deoxyribose, due to the absence of this group, it is impossible to form a phosphodiester bond between nucleotides and the DNA synthesis is stopped.
Answer:
1. The population will increase as they're better adapted to their environment and have a higher survival rate due to this helpful phenotype.
2. This happens to the population because this helpful phenotype might lead to less exposure to predation in which leads to a better survival fitness for the organism.
3. This mutation continues to exist as the organisms continue to successfully reproduce into the population due to being able to survive for longer.
Answer:
4
Explanation:
Because the mean time taken to turn from blue/black to orange/brown (in minutes) was the shortest, showing that the rate of reaction was the highest.
