Spindle fibers form a protein structure that divides the genetic material in a cell. [...] At the beginning of nuclear division, two wheel-shaped protein structures called centrioles position themselves at opposite ends of the cell forming cell poles. Long protein fibers called microtubules extend from the centrioles in all possible directions, forming what is called a spindle. Some of the microtubules attach the poles to the chromosomes by connecting to protein complexes called kinetochores. Kinetochores are protein formations that develop on each chromosome around the centromere, which is a region located near the middle of a chromosome. Other microtubules bind to the chromosome arms or extend to the opposite end of the cell. During the cell division phase called metaphase, the microtubules pull the chromosomes back and forth until they align in a plane along the equator of the cell, which is called the equatorial plane.

DNA contains the information to make proteins, which carry out all the functions and characteristics of living organisms.
<span>Superworms must be isolated and placed in complete darkness to pupate, all cooling does is kill them</span>
It is d
Explanation: 40/30=0.75 because there are 40 flowers in total and only 30 are red so the % of there being red flowers is 75% or 0.75 (same thing)
Here is the correct answer: <span>Most homologous pairs look alike. They carry genes for the same characteristics and line up on the chromosome in the same order
i hope this helps you out</span>
