The statement which correctly describes natural selection is (1) it favors the survival of certain members of the species and results in a change in the proportion of individuals with highly <span>adaptive traits.
Natural selection, by definition talks about the successful passing down of genes from older generations to younger generations. These then are better adapted to their environment. This is exactly what the first answer is about. </span>
Answer:
They can use a technique called Polymerase Chain Reaction. This can be done in a test tube or even in a organism. It usually relies on something called Thermostable DNA Polymerase and Taq polymerase. It requires DNA primers that is designed specifically for that DNA region (interest).
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:
Explanation:
The Electrically initiated Improvised Explosive Device (IED) generally consist of four component with the acronym PIES, the P stands for power sources which supplies electrical charge to the I; initiator contains a small amount of explosives such TNT or PETN which triggers the remaining amount of explosive, E is the explosive itself which is triggered into explosion by the initiator and finally the S, Swtich, example clock or a cell phone which determine the device explodes
Answer:
(Cystoplasm) and (Ribosomes) are common in most living cells
Explanation:
