Which of the following is the correct sequence in a cyclin-Cdk pathway?
A) Growth factor → cyclin → Cdk → receptor → DNA replication
B) Growth factor → receptor → Cdk → cyclin → DNA replication
C) Growth factor → receptor → cyclin → Cdk → DNA replication
D) Receptor → cyclin → Cdk → growth factor → DNA replication
