Cells will usually divide if they receive the proper signal at a checkpoint in the G1 phase of the cell cycle. In mammalian cells , this checkpoint is called the restriction point. The G1 phase is a phase of the cell cycle that takes place in eukaryotic cell division. In this phase the cell synthesizes mRNA and proteins in preparation for the subsequent steps leading to mitosis. It ends when the cell moves into the S phase of interphase.
Cancer cells multiply rapidly and normal cells don't.
The translation is initiated as the
small ribosomal subunit muddles to the mRNA. Then
the tRNA having the methionine binds to the start codon, and the large ribosomal subunit binds to the insignificant one.
Finally, t<span>he start codon indicates the start of
translation.</span>
Well, both subatomic particles of protons and neutrons contribute to the mass of the atom, and thus I believe that the correct response would be D. Protons and neutrons are located in the nucleus of the atom and both are responsible for the mass, atomic mass of the atom.
