Free and printable high-quality chromosome diagrams are available for you to help your study about DNA! The DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure. In the following diagrams, you’re provided the illustration of the chromosome. Click on the image of the diagram to enlarge and download by right-clicking and choosing the save as menu.
Explore the given chromosome diagram above. The chromosomes are found in the nucleus of the cell. Each chromosome has a constriction point called the centromere, which divides the chromosome into two sections. The location of the centromere on each chromosome gives the chromosome its characteristic shape and can be used to help describe the location of specific genes. These chromosomes carry all the information that help a cell grows, survive and reproduce.
Chromosomes are more condensed than the chromatin and they are essential for cell division. The chromosomes are replicated, divided and passed on to the daughter cells, to ensure genetic diversity and survival of the progeny. Duplicated chromosomes contain two identical copies known as chromatids or sister chromatids, they are joined by a centromere. You can see the illustration of the duplication on the diagram.
Chromosomes are the organized structure of DNA and proteins found in cells. Chromosomes play an important role that ensures DNA and we have 23 pairs of chromosomes. Hopefully, these diagrams will help you understand the system of DNA and chromosome. If you want to save the diagram, just click on the image and choose the Save menu!
