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.
Given question is incomplete as it lacks the group of choices. However, the group of choices associated with the question is as follows:
1. Organisms must display variation.
2. A trait must increase reproduction.
3. A trait must directly affect metabolism.
4. A trait must increase survival.
5. A trait must be able to be passed on to future generations.
Answer:
The correct answer is : option 3. A trait must directly affect metabolism.
Explanation:
The process that leads to change or adaption in the species or a population of the organism known as natural selection. In this process population exhibits the variation in the population due to the change or adaption.
This variation refers to the better traits and increased reproductive ability, suited to the environment than others which is also known as survival of the fittest as they increase their survival in comparison to the other population or species. Natural selection carries traits that are passed on to one generation to another.
Thus, the correct answer is option Is : 3. A trait must directly affect metabolism.
Answer:
B. $5
Explanation:
$95/10 percent = 9.5
9.5/2 (because it is halfway through the billing period) = 4.75
4.75 rounded up to the nearest tenths place is 5.
Answer:
Describing a trait as dominant does not mean it is the most common; it means that it is expressed over the recessive trait. For example, tongue rolling is a dominant trait, controlled by the dominant version of a particular gene (R). Individuals with one or two copies of R will exhibit tongue rolling.
