MatrixMode, glLoadIdentity, glTranslate, glRotate remvoved from OpenGL new versions?

One said that the functions like MatrixMode glLoadIdentity glTranslate glRotate will be removed from newer versions of OpenGL. I would like to know if this is true? As I am just begining to use OpenGL and I can't imagine how could anything be made without the calls of this functions?

What functions could then be used instead of this and why are or will they be removed? I would like to know where is the progress (logic) of this?

Thanks for the reply.
