Answer:
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as
The given balanced equilibrium reaction is,
At eqm. conc. 1.85 M 9.26M 0.254M
The expression for equilibrium constant for this reaction will be,
Now put all the given values in this expression, we get :
Thus the value of the equilibrium constant is
Answer: <u>Endonuclease enzymes used in molecular biology that cut DNA at specified points.</u>
Explanation:
Enzymes are specific protein types which bind to a substrate within a reaction, to increase the rate of reaction within the solution- they speed up the rate of reaction.
Restriction enzymes are bacteria-derived enzymes; these make cuts on deoxyribonucleic acid molecules or DNA. These are also called restriction endonucleases. They are utilized in molecular biology for DNA cloning and sequencing and cut DNA into smaller pieces called fragments.
Restriction enzymes make directed cuts on DNA molecules. They precisely target sites on DNA to produce mostly identical or homogenous, discrete fragments of equal sizes, producing blunt or sticky ends. In order to do this, they recognize sequences of nucleotides that correspond with a complementary sequence on the endonuclease called restriction sites.
There are several kinds that may require cofactors (chemical or metallic compounds that aid in enzyme activity) :
- Type I: cleave far away from the recognition site; require ATP and SAMe S-Adenosyl-L-Methionine
- Type II: cleave near to the site; require Magnesium
- Type III: cleave near to the site; require ATP which is not hydrolysed but SAMe S-Adenosyl-L-Methionine is optional
- Type IV: cleavage targeted to DNA that have undergone post transcriptional modification through certain types of methylation (addition of a methyl group)

Answer:
23 protons, 23 electrons, 33 neutrons
Explanation:
I don't know why my answer got deleted but no worries, I can answer again. The number of protons and electrons is equal to the atomic number which is 23 and the number of neutrons is 56 - 23 = 33 because atomic mass denotes the number of protons and neutrons.
Answer:
Explanation:
Using Rydberg's Equation for hydrogen atom:
Where,
= Wavelength of radiation
= Rydberg's Constant
= Higher energy level
= Lower energy level
We have:
The relation between energy and wavelength of light is given by Planck's equation, which is:
where,
E = energy of the light
h = Planck's constant
c = speed of light
= wavelength of light
Thus energy of a photon that is ejected from a hydrogen atom when an electron relaxes from the 6th to the 3rd energy level is
