What are leukocytes?</h2>
Leukocytes are colorless cells that circulate in the blood and belongs to the body's immune system and helps the body fight infections and other diseases.
<h2>
What is their function?</h2>
Leukocytes are responsible for fighting other diseases and protecting your body from infections. Since they are part of the immune system, leukocytes circulate your blood and help cure injuries or illness.
Answer: 23 chromosomes
In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells. The number of chromosomes in a single set is represented as n, which is also called the haploid number. In humans, n = 23.

Smaller DNA fragments migrate <u>more quickly</u> and further over a given period of time than larger fragments.
<h3>Gel electrophoresis and DNA fragments</h3>
Gel electrophoresis is a method to separate DNA fragments (or RNA and other macromolecules) based on their size and charge, involving a gel called agarose. The molecules will travel through the gel at different speeds or in different directions, which allows them to be separated from each other.
Because all DNA molecules have the same amount of charge per mass, gel electrophoresis of DNA fragments separates DNA molecules based on size only. Shorter pieces of DNA travel through the pores of the gel more quickly than longer ones do.

The point at which the toxin would interrupt normal cell signalling in the pathway is the signal amplification.
This is because of the G-protein uncoupling and inhibition of signal amplification by pertusis toxin. Pertusis toxin released by the bacteria Bordetella pertusis and prevents signal that is amplifying from the protein. The G-protein coordinates the interaction between membrane bound receptor proteins and the effector proteins involved in the intracellular signalling. The toxin promotes the uncoupling of this heterotrimetric protein and also inhibits the amplification thus preventing the interaction of the receptor proteins and the second messengers.
True, because atoms bonds together and form molecules in different sizes and shapes.
