What occurs during G1 and G2 in the cell cycle?

- G1 is an intermediate phase occupying the time between the end of cell division in mitosis and the beginning of DNA replication during S phase. During this time, the cell grows in preparation for DNA replication, and certain intracellular components, such as the centrosomes undergo replication.

- The last part of interphase is called the G2 phase. The cell has grown, DNA has been replicated, and now the cell is almost ready to divide. This last stage is all about prepping the cell for mitosis or meiosis. During G2, the cell has to grow some more and produce any molecules it still needs to divide.

The Freedom riders were a group of white and black American citizens who rode buses across the Deep South in protest of segregated bus policies. They intentionally broke segregation laws as a means of peaceful protest. Their goal was to ultimately get rid of segregated facilities across the southern states.

They were true American heroes because they remained nonviolent even though they were physically attacked. At one point during their rides in 1961, their bus was set on fire by an angry mob. Despite all of this torment, these individuals continued on their journey and refused to retaliate with violence.
