I put interphase and telophase and some other people did too! I don't see why they wouldn't accept it - interphase is when all of the DNA replicates, so the amount of DNA doubles. Then telophase is when it all gets separated into two different cells - so theoretically halving the chromosomes. Don't see the problem!

Aren't interphase and telophase 'phases' not 'processes'...? The 'processes' taking place were DNA replication and cytokinesis no? ._.

Is the MS out?

I wrote semi-conservative replication and cytokinesis. I Think they will be accepted on the MS.

You right about the processes vs phases thing mate. Mark scheme will be like 'don't accept stages such as *****'

Yeah I agree, it won't be high. It caught everyone by surprise, too much application and synoptic links which will pull it down
