Answer:
true
Explanation:
Similarly, expression of a human gene in yeast and bacteria allows pharmaceutical companies to produce insulin to treat diabetic patients. In 2020, scientists had their first successful human trial with CRISPR (a genetic engineering technique), to correct a mutant gene that causes sickle cell anemia, a painful and sometimes deadly blood disease.
Answer:
250
Explanation:
According to the question the number of bacteria population becomes double in 9 hours to that of 1 hr that means bacteria is dividing in 9 hours. Each time the bacteria divides, the numbers become double.
As we have found that bacteria is dividing in 9 hours so for the first 9 hours the number will be same as initial population i.e. 250. But just after nine hours the population will be double i.e. 500.
So, after 3 hours the population will be same as initial population, 250.
