When DNA coils into a chromosome, it keeps its shape with the help of associated proteins. Where the DNA is very tightly coiled, and the proteins very condensed, that region appears as a dark band (G-band). G-bands are not very rich in genes, which means that it's ok that the DNA is tightly coiled, because it does not have to be very accessible anyway. Note that these bands are only visible when certain types of dye are used. Other types of dye will case gene-rich regions to stain darker and gene-poor regions to stain more brightly.

What else can I help you with?
Does chromosome number indicate whether an organism is a plant or animal?
no
If a rock has bands of light and dark layers its what?
It could be a sedimentary rock or a foliated metamorphic rock exhibiting alternating bands of light and dark minerals.
What do elevated bands mean on a white blood cell count?
Elevated bands indicate an increase in immature white blood cells, which are released by the bone marrow in response to an infection or inflammation. This can be a sign of an active immune response in the body.
What is the segregation of light and dark colored minerals into thin layers or bands?
The segregation of light and dark colored minerals into thin layers or bands is known as foliation. This occurs during the process of metamorphism, where the minerals align in parallel layers due to the deformation and recrystallization of the rock under intense pressure and temperature conditions. Foliation gives the rock a banded appearance and can indicate the direction of pressure during its formation.
Planet covered with dark and light bands?
Saturn is the planet that will answer your question
How do you cytogenetically determine band levels using chromosome 10?
To determine band levels on chromosome 10 cytogenetically, you would use staining techniques like Giemsa staining to create a banding pattern. This banding pattern consists of light and dark bands that are specific to different regions of chromosome 10. By comparing the banding pattern to a standardized map, you can determine the band levels on chromosome 10.
A bands are dark bands?
Yes, in striated muscle you can think of the "A" bands as the dArk bands and the "I" bands as the lIght bands.
If a rock has bands of light an dark layersit is?
likely a sedimentary rock, which forms in layers over time. The light and dark bands may indicate different compositions or sediment types deposited during different periods. These rocks often provide clues about past environmental conditions.
Do smooth muscle have alternating dark and and light bands on them?
Yes, smooth muscle has alternating dark and light bands known as the A and I bands, respectively.
Does chromosome number indicate whether an organism is a plant or animal?
no
Large dark structure that contains the chromosome?
Nucleus
Which proteins form light and dark bands?
In striated muscle fibers, light bands (I bands) are formed by the protein actin, while dark bands (A bands) are formed by the protein myosin. These proteins play a crucial role in the sliding filament theory of muscle contraction.
If a rock has bands of light and dark layers its what?
It could be a sedimentary rock or a foliated metamorphic rock exhibiting alternating bands of light and dark minerals.
What do the first 3 bands on a resistor indicate?
The first 3 band on a resistor indicate the value of that resistor.
Skeletal muscle cells are striated that is they have alternating dark and light bands called repectively?
A and I bands
Two muscular tissues that show light and dark bands?
Skeletal and cardiac muscle tissues are both considered as striated, which means that they have light and dark bands.
Combination of alternating dark A bands and light?
The alternation dark and light bands are found in muscles of humans and animals. They give the muscle fibers their striated appearance.
