Question: Which are the components of the pre-replication complex (pre-RC) in eukaryotes?

Context:
 The first step of replication initiation is the assembly of pre-replication complex (pre-RC). Since 1973, four proteins, Cdc6/Cdc18, MCM, ORC and Cdt1, have been extensively studied and proved to be pre-RC components. Recently, a novel pre-RC component called Sap1/Girdin was identified. Sap1/Girdin is required for loading Cdc18/Cdc6 to origins for pre-RC assembly in the fission yeast and human cells, respectively. 
In eukaryotes, the pre-replication complex is composed of the Origin Recognition Complex (ORC), Cdc6 and the MCM replicative helicase in conjunction with Cdt1. Eukaryotic ORC is considered to be composed of six subunits, named Orc1-6, and monomeric Cdc6 is closely related in sequence to Orc1.
The sequencing of the Plasmodium genome has also revealed the apparent absence of many key components (e.g. Cdt1, DDK and Cdc45) of the eukaryotic cell cycle machinery that are responsible for the formation of the pre-replication complex (pre-RC). We have characterized the Plasmodium falciparum minichromosome maintenance complex (MCM) that plays a key role in the transition of pre-RC to the RC. Similar to other eukaryotes, the Plasmodium genome encodes six MCM subunits. 
During pre-replication complex (pre-RC) formation, origin recognition complex (ORC), Cdc6, and Cdt1 cooperatively load the 6-subunit mini chromosome maintenance (MCM2-7) complex onto DNA.
ORC1 is an essential component of the pre-replicative complex (pre-RC) that licenses eukaryote DNA replication origins.
In higher eukaryotes, the pre-replication complex (pre-RC) component Cdt1 is the major regulator in licensing control for DNA replication.

We examined the mRNA expression of the components of pre-replication complex (Pre-RC), CDC6, CDT1, and MCM2-7
Replication initiation is a multi-step process involving many factors including ORC, Cdt1p, Mcm2-7p and other proteins that bind to replication origins to form a pre-replicative complex (pre-RC)
The sequencing of the Plasmodium genome has also revealed the apparent absence of many key components (e.g. Cdt1, DDK and Cdc45) of the eukaryotic cell cycle machinery that are responsible for the formation of the pre-replication complex (pre-RC).
Different components of the ORC complex and Cdc6 stimulated prereplicative complex (pre-RC) formation and replication initiation when fused to the GAL4 DNA-binding domain and recruited to plasmid DNA containing a tandem array of GAL4-binding sites.
Cdt1, DDK and Cdc45) of the eukaryotic cell cycle machinery that are responsible for the formation of the pre-replication complex (pre-RC).
Recently, a novel pre-RC component called Sap1/Girdin was identified.
MCM2-7 is a key component of the prereplicative complex (pre-RC), which is loaded onto chromatin by the concerted action of origin recognition complex, Cdc6, and Cdt1.
The pre-replicative complex (pre-RC) is formed at all potential origins of replication through the action of the origin recognition complex (ORC), Cdc6, Cdt1, and the Mcm2-7 complex.

Answer: The components of the pre-replication complex (pre-RC) in eukaryotes are:
1) Cdc6/Cdc18, 
2) MCM, 
3) ORC1-6,
4) Cdt1 and
5) Sap1/Gi.
Exact answer: Cdc6/Cdc18, MCM, ORC1-6, Cdt1, Sap1/Gi
