Question

During prophase, DNA condenses into X-shaped structures called what

Answer 1

During prophase, DNA condenses into X-shaped structures called chromosomes, consisting of sister chromatids joined at the centromere.

Step-by-step explanation:

During prophase, DNA condenses into X-shaped structures called chromosomes. These chromosomes are visible under a microscope due to the tightly wound chromatin. Each chromosome at this stage consists of two identical copies known as sister chromatids, which are joined together at a specific region named the centromere. The centromere contains proteins, such as kinetochores, where spindles attach during mitosis to assist in the movement of the chromosomes.

Answer 2

Chromosomes

Step-by-step explanation:

During interphase, the DNA is relatively "loose". However, during prophase, the DNA (in the DNA-protein complex called chromatin) becomes condensed. These condensed structures are called chromosomes, and are visible under a microscope. This is how the DNA is properly organised prior to cell division
