During meiosis, a defect occurs in a cell that results in the failure of microtubules, spindle fibers, to bind at the kinetochor
mario62 [17]

Answer:

The resulting cells will not receive the correct number of chromosomes in the gametes, a condition known as aneuploidy.

Explanation:

Formation of functional microtubule spindle fibers and their attachment to kinetochores of chromosomes is required to ensure their alignment st the cell's equator during metaphase. During anaphase, shortening of these microtubules pulls the chromosomes to the opposite poles. These events ensure the distribution of the correct number of chromosomes among the daughter cells. The presence of defective microtubules would not allow proper distribution of chromosomes to the daughter cells and would result in the presence of an abnormal number of chromosomes (aneuploidy).

A hypothetical three-step metabolic pathway consists of the intermediates W, X, Y, and Z, and the enzymes that catalyze the reac
GenaCL600 [577]

Answer:

ZBWCYAX

Explanation:

Equation for the intermediates: Z↔W↔Y↔X

1) B catalyzes the breakdown of Z, therefore inhibiting B leads to the build up of Z.

2) If enzyme C is inactive then the organism will not  receive Y to grow, thus Y is a by-product of C.

3) If A is inhibited then W, Y and Z build except for X, thus it make sense that A catalyzes a reaction that leads to X as a by-product.

4) Inhibiting C leads to the reaction toward making Z and W, thus it catalyzes the breakdown of C directly and Z indirectly.
