Answer:
Explanation:
Blue-white screening is a method for distinguishing proof of (recombinant bacteria). It depends on the capacity of ( B-galactosidase) to separate lactose. Blue-white tests exploit the molecule called (x-gel)_ which is like lactose in that it is severed by B-galactosidase. When separated, the (5-bromo-4-chloro-indoxyl) (same as past) turns _(_blue). In the event that uncleaved, which implies a non-function B-gal gene, the X-gal remains (white)_. Subsequently, a __(white) bacterial province implies the B-galactosidase gene isn't practical, and in this way there ___lacz__ a recombinant gene embedded into the vector.
Answer:
1. During the__ Attachment ____stage, enzymes digest cell wall and membrane material so that the viral nucleic acids can enter into the host cell.
2. During the ___ Penetration __ stage, the capsid of virus combines with receptors on the host cell's plasma membrane.
3. During the__ Biosynthesis ____stage, viral nucleic acids and capsid components are produced.
4. During the ___ Release __ stage, lysozyme enzyme is produced, is rupturing the cell membrane and releasing viral particles.
5. During the___ Maturation ___stage, viral nucleic acids and capsid components are assembled to produce viral particles.
Explanation:
I have attached picture explanation whole lytic cycle.
Independent assortment.
It describes how different genes separate from each other randomly into different gametes.
Answer:
True
Explanation:
Lewis structures are diagrams that represent the valence electrons of atoms within a molecule. These lewis structures help visualize the valence electrons of atoms and molecules, whether they exist as lone pairs or within bonds.
Answer
D. nitrogen, oxygen, and trace amounts of other gases.
Explanation:
Earth is composed of an atmosphere that sustains life. It protects its inhabitant against direct radiation from the sun that could be of adverse effect. The earth consist of Nitrogen-78%, oxygen-21%, carbindioxize- 0.04%, Argon - 0.93% and trace element such us helium, hydrogen, krypton and water vapour. The earth consist of 5 different layers this include the stratosphere, thermosphere,
Atmosphere, troposphere, Mesosphere.
Earth is the only planets that sustains life and its has the ability to accommodate different living organism because of its diverse climatic condition.
Option D is the answer because Nitrogen and oxygen are contain in large amount and otherwise trace quantity.
