Final answer:
False , Genes are located on chromosomes, not spindles. During cell division, spindle fibers attach to chromosomes at the kinetochores to pull sister chromatids apart, ensuring an equal division into daughter cells. Linked genes are found on the same chromosome but do not interact directly with spindles.
Step-by-step explanation:
The statement that genes are located at specific positions on spindles is false. Genes are actually located on chromosomes, not spindles.
During metaphase of mitosis, chromosomes, which consist of sister chromatids, line up at the cell's equator. Spindle fibers, which are formed by microtubules that extend from the centrosomes, attach to the kinetochores of the chromosomes, not the genes themselves.
These spindle microtubules are essential for pulling sister chromatids apart during anaphase and ensuring that they are evenly divided into the daughter cells.
During prometaphase, microtubules from the mitotic spindle attach to the kinetochores of chromosomes. Here, it is important to note that each chromosome contains hundreds or thousands of genes, and these are referred to as linked genes when they are located on the same chromosome.
Spindle fibers do not attach to genes directly; instead, they interact with the chromosomes that carry genes at the centromeres.
Overall, spindles are part of the cellular machinery involved in the segregation of chromosomes during cell division, while genes are the units of heredity organized linearly along the DNA of the chromosomes.
