Automated sequencing machines order the DNA fragments from a PCR reaction into size order using a technique called capillary electrophoresis.
In capillary electrophoresis, the DNA fragments are loaded into a narrow, tube-like capillary filled with a gel-like matrix. An electric field is then applied, causing the DNA fragments to move through the gel based on their size and charge.
Automated sequencing machines use capillary electrophoresis to order the DNA fragments in a fast, efficient, and accurate manner, making it possible to sequence large amounts of DNA quickly.
The resulting data is then used to determine the sequence of the DNA, which is important in a wide range of applications, including genetic research and disease diagnosis.

As sound waves travel into the ear, they pass from the auditory canal to the: A: tympanic membrane, auditory ossicles, oval window, perilymph, scala vestibuli of the cochlea.
The human ear is responsible for converting sound waves into electrical signals that the brain can interpret as sound. The process begins when sound waves enter the ear and travel through the auditory canal. The sound waves then reach the tympanic membrane, also known as the eardrum, which vibrates in response to the sound.
The vibrations of the tympanic membrane are transmitted to the auditory ossicles, a set of three small bones in the middle ear, which amplify the sound and transmit the vibrations to the oval window, an opening in the inner ear. The vibrations then move from the perilymph, a fluid that surrounds the inner ear, into the scala vestibuli, one of the two fluid-filled canals in the cochlea, a spiral-shaped organ in the inner ear.
The cochlea is responsible for transforming the mechanical energy of the sound waves into electrical signals that can be transmitted to the brain via the auditory nerve. The electrical signals are then interpreted by the brain as sound. The process of converting sound waves into electrical signals in the cochlea is known as audition.

how is fiber different from starches? multiple choice question. fiber is a single substance, whereas starches are a group of substances. fiber is readily absorbed and transported to the liver for energy. the chemical bonds in fibers that hold the sugar units together cannot be digested, preventing the absorption of these sugars. fiber is easily metabolized by intestinal bacteria.
Starches are a collection of substances, whereas fiber is a single substance. Because the chemical connections in fibers that hold the sugar units together are indigestible, these sugars cannot be absorbed.
Fiber is a form of carbohydrate, just like sugars and starches. However, fiber differs from sugars and starches because it is not absorbed by the body in the same way. It is digested unaltered by the human body's small intestine before being fermented in the large intestine. Soluble and insoluble fiber are the two different forms of fiber. Plant pectin and gums are examples of soluble fiber that dissolve in water. Water doesn't cause insoluble fiber to dissolve. It contains cellulose from plants and hemicellulose.

Function of β-galactosidase is that it cleaves the disaccharide lactose to produce galactose and glucose which then ultimately enter glycolysis.
An enzyme called lactase, also referred to as β-galactosidase, is in charge of hydrolyzing lactose. The food processing industry uses this enzyme in a variety of ways. Because of the low acidity that results in diarrhea, gas, and cramps when there is too much lactose in the colon, tissues are frequently dehydrated and calcium absorption is lowered.
Basically, β -galactosidase is a tetramer made up of four identical polypeptide chains, each of which has 1023 amino acids, resulting in the formation of five distinct structural domains. β-galactosidase also causes transgalactosylation reaction of lactose to allolactose which then finally cleaved to monosaccharides. One of these domains is a jelly roll barrel, and the others are made up of fibronectin, a -sandwich, and a central domain with a TIM-type barrel that also functions as the active site.
