Prior to CO2 fixation, Activation of RUBISCO/Carbamylation of RUBISCO takes place

1. Two protons are released. 

2. Binding of CO2 molecule on NH2 group

3. Binding of Mg2+ concentration upon illumination

One is unequal crossing over, in which recombination happens between different positions on chromosomes that are misaligned during meiosis. 

Another is replication slippage, in which the DNA polymerase loses its place and copies a segment of chromosome twice.

Shortly after transcription initiation, Pol II is paused 30 nucleotides downstream from the initiation site, waiting for the recruitment of the capping enzymes to add the cap to the 5’ end of nascent RNA. Without this protection, nascent RNA may be vulnerable to attack by 5’–3’ exonucleases, and such trimming may induce the Pol II complex to fall off of the DNA template.
