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.
Colored bands of light form in the sky during a sunset due to the scattering of sunlight by particles in the Earth's atmosphere. The shorter wavelengths of light, such as blue and green, are scattered more easily, leaving the longer wavelengths, like red and orange, to dominate the sky's colors during sunset.
Glow-in-the-dark objects produce phosphorescent light. This type of light is created when certain materials absorb and store energy from ambient light, then release it slowly over time in the form of visible light.
If you shone monochromatic light on a diffraction grating it would alternate bright and dark bands. Only white light white light shone through a diffraction grating would produce a band of colors.
Glow-in-the-dark silicone bracelets are made with phosphorescent materials that absorb and store light energy when exposed to light. When in the dark, they slowly release this stored light energy in the form of a dim glow. The process is called phosphorescence.
In dark field microscopy, the light that reaches the objective only comes from light rays that are scattered by the object being observed. These scattered rays are then captured by the objective lens, illuminating the object against a dark background. The dark field condenser blocks the direct light rays that would otherwise create a bright background, allowing only the scattered light to form the image.
Both types of muscles have striations in their cells for greater contraction. These striations are in the form of crossing and alternating light and dark bands.
interference is the phenomenon of redistribution of energy , when two light waves of same frequency and nearly same amplitude superimpose upon each other they form light and dark bands ,this process is known as interference of light.
The bands of light and dark are classic signs of Gneiss (Gneissose banding), but Gneiss is not necessarily shiny. It may be sparkly, but not shiny. However, a Slate IS shiny, but does not have the pretty banding. Another consideration is Schist, which has similar characteristics to Gneiss. My advise is that if you are classifying a rock that you are looking at, consider the grade of metamorphism, as it certainly is metamorphic. Also consider the mineralogy: what are the light and dark bands? Quartz, Feldspar (light)? Mica (biotite) (dark)? There are many possibilities. The mineralogy will help determine the original sedimentary rock, which you can then use to determine the metamorphic sample you have.
Saturn's bands are more subtle, with less contrast and variation in color compared to Jupiter's. Saturn's bands are also wider and less pronounced than Jupiter's distinct, dark belts and light zones. Additionally, Saturn's rings overshadow its bands in visibility and recognition.
To develop the position of the proteins or nucleic acids bands. The most common stains for proteins are Coomassie brilliant blue and Amido black (among others), and for nucleic acids is ethidium bromide (this compound form a complex with the DNA double helix and is fluorescent under short-range UV light).

Shadows can only form when there is light present. A shadow is the result of a solid object blocking visible light. As a mirror is a solid object it can indeed produce a shadow, but nothing can form a shadow in the dark, there must first exist a light source.
No, DNA does not contain dark matter that codes for specific structural proteins. DNA is made up of specific sequences of nucleotides that code for proteins through the process of transcription and translation. Dark matter is a hypothetical form of matter that has not been directly observed or detected in DNA.
No. Gneiss has foliation in the form of alternating light and dark bands.
The two main groups of metamorphic rocks are foliated and non-foliated. Foliated metamorphic rocks show layering and parallel alignment of flat mineral crystals (ex. micas). The "banded texture in metamorphic rocks" is one of the specific kinds of foliated textures. It is referred to as gneissic banding. Essentially, this texture displays alternating layers of light and dark minerals. These rocks are called gneiss- the light bands form from quartz and feldspars, while the dark ones form from ferromagnesian minerals.
The possessive form of the plural noun bands is bands'.Examples:The bands' lengths can be adjusted for the size of the bales.The bands' uniforms are the colors of their respective schools.
