Answer:
spindle fibers act as guides for the alignment of the chromosomes as they separate later during the process of cell division.
Explanation:
They play a role in mitosis of animal cells and plant cells are able to reproduce without them.
Research however has shown that mitosis can take place in animal cells after centrioles have been destroyed. ... In higher plants mitosis takes place perfectly satisfactorily with microtubules forming spindle fibres but without the help of centrioles.

Answer:
Mitosis
Explanation:
Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus.
1) Mutations are caused by changes in nucleotide bases. these altered base formed different amino acid depending upon nucleotide base sequence that code specific amino acid. ... even though some mutations, can have a more effect on amino acid coding, which can affect what kind of proteins are produced.

Answer:
Western blot should be performed
Explanation:
Generally ELISA test is sensitive to elevated antibodies levels in the blood. Because HIV infection is characterise with increases in antibodies levels(HIV-antibodies levels)of the body, it is usually the first screening test for HIV,however it is also sensitive to elevated antibody from any other infection apart from HIV. Therefore for confirmation, the procedure is to run a second ELISA test, to determine if the antibody rise was due to HIV or not. If the second test turns positive, then Western blot can be applied.
The Western blot through secondary and primary antibodies binding , separates the investigating antibodies, and identity the specif HIV antibodies present to give a positive HIV-antibody, confirming ELISA positive test.
Thus for confirmation of HIV specific antibodies of the blood; ELISA test followed by Western blot is ideal
