Restriction enzymes and or restriction endonucleases are involved at recognizing specific sequence of nucleotides and cutting or splicing them at appropriate regions to produce fragments that can either be sticky ends or blunt ends depending on where they cut and the nature of nucleotides involved within the fragments. They play an important role in genetic engineering, as geneticists can use them for placing into extra chromosomal information and or content of plasmids in certain bacteria, from other sources, for instance antibiotics, grow and or produce many individual colonies of bacteria, isolate them and one would have many sequences for instance that can code for an antibiotic that can be extracted and used further. Assuming the bacteria's plasmid can take in that sequence.
Well fossil fuels are a finite resource and at the rate we are using them, yes they will run out. but not anytime soon. but yes. we use them faster than they can be created. they WILL run out eventually.
Answer:
B
Explanation:
Oxygen is the final acceptor of electrons in the process of oxidative phosphorylation. Without oxygen, the process becomes jammed with electrons.
I would say A. Because it seems like a logical explanation.
Every species has different timespans. Some butterflies live 6 months, other live 7 years. However, most of their time they are caterpillars or are in a coccoon. Up to 6 years
