Chapter 9, Problem 6FTB
Summary Introduction
To review:
The given blank space in the statement, “chromosomes attach to spindle microtubule at a structure are called _____. Some spindle microtubules called _____ microtubule, do not bind to the chromosome but have free ends that overlap along the equator of the cell. These microtubules push the poles of the cell apart.”
Introduction:
The chromosome consists of deoxyribonucleic acid (DNA) which carries the genetic material. The center constricted point of the chromosome is known as the centromere. The chromosome majorly has two arms: shorter p arm and a longer q arm. They hold the two sister chromatid together.
