Answer:
The correct answer will be-
1. Law of inheritance
2. Law of Independent Assortment
3. Meiosis
Explanation:
Gregor Mendel is known for his work on the pea plants to study the pattern of inheritance of traits in a population.
On the basis of his work, Laws of inheritance were proposed in which the main three laws were the Law of dominance, Laws of segregation and law of independent assortment.
The Law of inheritance suggested that factor (genes) responsible for a trait come in pairs and is inherited one from each parent to the offspring.
The law of Independent Assortment stated that these genes segregate and passed on to the offspring independent of each other.
The cell division associated with the formation of a germ cell is known as meiosis which produced four daughter cells with different genetic material.
Answer:
The correct answer is B) binds to the complementary sequence of target mRNAs
Explanation:
Double stranded RNA can be used to block the expression of target mRNAs.
At first the introduced double stranded RNA is being separated into single stranded RNAs .One of the Single stranded RNA is degraded.
The remaining Single stranded RNA binds to the target mRNA by complementary base pairing and blocks the expression of that single stranded RNA.
The missing part of the question is as follows:
Phrase indicates a limit to the scientific accuracy of the experiment?
Answer:
The correct answer is - a sample size of 300 people.
Explanation:
In the given research Marcus developed a drug that is already 200,000 people taking the drug, and the scientist takes sample size of only 300 people for the experiment.
The sample is very small as compared to the total population who participated in the research. A sample size of 300 people is very small compared to 200,000 people. Such a small sample size will not give the proper idea and any effective result, there would be chances to miss some aspect or effect of the drug to be missed, so, this can be the limiting factor to the experiment.
