Pigmentation of skin is due to.
Molecular probes are used for many genetic disorders like?
Mark the correct statement.
- Here, option (C) is correct as Galactosemia is metabolic genetic metabolic disorder due to deficiency of the enzyme uridyl transferase.
- While, carboxypeptidase is a protease enzyme that acts on 'C' terminal end of a protien or peptide.
- And, in pancreatic juice trypsin, amylase and lipase are present.
Isopycnic or equal density centrifugation is achieved in
Which of the following statement can be related to colorimeter?
A colorimeter is a light-sensitive device user to measure the transmittance and absorbance of light passing through a liquid sample. It measures the intensity or concentration of the color that develops after adding a specific reagent to a solution. The working of colorimeter is based on Beer-Lambert law which states that absorption of light transmitted through the medium is directly proportional to the medium concentration.
On which of the following laws the working of the colorimeter is based upon?
A colorimeter is a device that measures the absorbance and transmittance of different wavelengths of light in a solution. This is called Beer-Lambert law.
In which of the following types of centrifugation, the components of separation are based on size, shape and density?
In differential centrifugation particles of different density, size and shape in a suspension sediment at different rates, with the larger and denser particles sedimenting faster. These sedimentation rates can be increased by using centrifugal force. Thus the correct answer is 'Differential centrifugation'.
