insertional inactivation is basically about the inactive of second marker where the protein cannot be longer produced. the suitable example is pUC19 where the lacZ gene that encoded for beta-galactosidase cannot be longer produced when the foreign gene is inserted in it..

What is the principle of competitive exclusion principle?

The principle of competitive exclusion states that two species cannot occupy the same niche. If they do occupy the same niche, competition for food, space and limited resources will occur. Too much competition will occur until the best-adapted species cause the disappearance of the other.


Do you still use Charles Darwins theory today?

Yes, Darwin's theory of evolution by natural selection continues to be a fundamental principle in the field of biology and is widely accepted by the scientific community. It is used to explain the diversity of species and their adaptations to different environments.


Which of Mendel's principles is most important in explaining the production of males and females?

Mendel's principle of independent assortment is most important in explaining the production of males and females, as it describes how different traits, such as those determining sex, are inherited independently of one another. This principle helps explain the random assortment of chromosomes during meiosis, which ultimately determines the sex of offspring.


Describe mendel's second set of experiments?

he drew a table and decided to count the number of plants with each trait that turned up he thought it might help him to explain his results


Explain relationship between the diameter of vessels and the velocity of blood?

As vessel diameter decreases, blood velocity increases due to the principle of conservation of flow rate. This relationship is described by Poiseuille's law, which states that blood flow is directly proportional to the fourth power of vessel radius. Therefore, smaller vessels result in faster blood flow velocities.
