According to ‘Finch and Klug’, state the solenoid model of nucleosome.

Accroding to 'Finch and klug'. State the solenoid model of nucleosome.

Who is proposed the Solenoid model ?

According to the Lock and Key model, the mechanism of an enzyme catalysed reaction (where E= enzyme , S = substrate , ES = enzyme -substrate activated complex and P = product) is -

According to Bohr's atomic model the electrons move around the nucleus in a circular orbit the electrons can move only in that orbit in which a angular momentum of electrons I sintegral multiple of h/2pi i.e. mvr=nh/2 pi where n=principle quantum number r=radius of orbit v=velocity of electron h=plank's constant the energy of orbit in which electron is moving is given by E_n=-13.6(z^2/n^2)eV//"atom" The radius of which of the following orbits is the same as that of the first Bohr's orbit of hydrogen atom?

According to Bohr's model , the ratio of the energies of the electron in the first orbit of hydrogen atom and He^(+) atom is

The electron in a hydrogen atom makes a transition n_1 to n_2 , where n_1 and n_2 are the principal quantum numbers of the two states. According to the Bohr model , the time period of revolution of electron in initial state is 8 times that in the final state. Which are possible values of n_1 and n_2 ? A 4,2 , B 8,2 , C 8,1 ,D 6,3 .
