taurus [48]3 years ago
5 0

Solution:

In amino acid composition analysis, amino acids are visualized after separation using the chemical reagent isfluorescamine.

Non- fluorescent reagent that reacts readily under mild conditions with primary amines in amino acids and peptides to form stable, highly fluorescent compounds. Low background due to hydrolysis. Useful for the fluorometric assay of amino acids, protein, and proteolytic enzymes. Effectively blocks newly generated amino termini in protein sequence analyses.

The right answer is fluorescamine.

Olin [163]

Answer:

Because each duplicated chromosome consists of two identical sister chromatids joined at a point called the centromere, these structures now appear as X-shaped bodies when viewed under a microscope. Several DNA binding proteins catalyze the condensation process, including cohesin and condensin.

What five criteria must be met for a substance to be a mineral.
mafiozo [28]

Minerals may be defined as the combination of two or more elements of a substance.

<u>Five criteria that exhibits a particle to be minerals; </u>

  • They are natural and not man-made.
  • Inorganic i.e. not made by any organism.
  • Minerals are solids, not liquid or gas.
  • They have a definite chemical structure.
  • The atoms in minerals are arranged systematically and are arranged in a repeated pattern.

Within a phase, a change in heat causes the temperature of the substance to _____ as the _____ energy of the molecules changes.
Nana76 [90]

Within a phase, a change in heat causes the temperature of the substance to change as the kinetic energy of the molecules changes. During a phase change, however, a change in heat causes a change in the potential energy of the molecules and the temperature will stay the same.

<h3>What is Potential energy?</h3>

Potential energy may be defined as a form of accumulated energy that relies upon the comparative situation of diverse parts of a system.

The above passage determines the differentiation between the kinetic and potential energies with respect to temperature and phase change.

Therefore, it is well described above.
