Which regions of the chromosomes will typically be in the form of hereochromatin?

There are certain regions that are tightly coiled. When the DNA is stained with a dye these regions appear in a dark band and are called hetrochromatin. They are the part of the chromosome that are not actively expressed in the cells. A heterochromatin in one cell may be functional in other cells.

Chromosomes form during what?

Which sequence is correct for mitosis?
Chromosomes form (prophase),Chromosomes line up (metaphase),Chromosomes separate (anaphase) ,Nuclei form (telophase)
What must DNA do Before chromosomes can form?
DNA wraps around protein before chromosomes can form.
What forms chromosomes?
chromatin along with chromosomal matrix form the chromosomes.

What is the phase where chromation condenses form to chromosomes?
The cell's chromatin condenses into chromosomes during prophase. In contrast, telophase is where the chromosomes loosen to form chromatins.
Which organisms have circular chromosomes?
Prokaryotic organisms such as Bacteria have circular form of chromosomes
How is eukaryotic chromosomes similar to a prokaryotic chromosome?
Simplified version that an intro biology course would look for: Eukaryotes have multiple pairs of linear chromosomes. The gene-coding sequences are interspersed with non-coding regions that may control gene regulation. Within a gene sequence, there are exons (coding regions) and introns (non-coding regions that will be removed from the mRNA). Prokaryotic chromosomes are tightly wrapped around proteins called histones. Eukaryotic chromosomes are contained in a nucleus. Prokaryotes have 1 circular chromosome, and may have smaller extrachromasomal DNA in the form of plasmids. Prokaryotic DNA does not have the non-coding regions or introns. Bacteria do not have histones, but archaea have histone-like structures associated with their chromosomes. Prokaryotic chromosomes exist in the cytoplasm. Reality about Bacterial Chromosomes: Although many have only the 1 circular chromosome, there are many exceptions to this rule Borrelia burgdoferi (corkscrew-shaped bacteria that causes Lyme Disease) has 17 linear chromosomes and many plasmids.
When do homologus chromosomes form?
Prophase I
